Introduction

1. Introduction The FC14 controller is used for climate control in the agricultural sector. It regulates ventilation and heating for one section. Communication The computer can be included in a serial communication loop (using a communication print). The computer can then be remote controlled using a Personal Computer.

Caution

A computer is a piece of electronic apparatus. Any eventual technical malfunctioning can cause considerable damage. As a result of the increasingly strict demands laid down by insurance companies, it is necessary to connect the alarm contacts of the various computers to a central alarm unit. In addition, Fancom advises the installation of an extra, independent alarm system (e.g. a minimum/maximum thermostat).

Safety

2. Safety instructions and warnings Read the safety instructions carefully before operating the system. The installation of the computer and trouble shooting must be carried out by an authorized technician/installer, according to the prevailing standards.

Caution

1. Check your computer regularly for correct functioning. It is an

electronic apparatus and should therefore give an alert during any system failures. Fancom has done everything electronically possible to ensure that an alarm is given during any such failure. Unfortunately, this cannot be 100% guaranteed because not all circumstances are under Fancom’s control.

2. Fancom takes no responsibility for any possible damage as a result of incorrect settings and a non- or partially functioning installation.

3. Ask your installer if the alarm contacts of each computer have been connected to a separate alarm system circuitry.

4. Check the computer regularly for possible damage. Any damage should directly be reported to your installer.

A damaged computer is dangerous!

5. Do not use running water (high pressure cleaners) to clean your

computer.

The computer is water resistant, not waterproof!

6. Important

Do not switch off the computer when houses are unoccupied; this is to protect the computer against condensation.

Working

3. Working 3.1 General The Fancom FC14 climate controller is suitable for use in intensive animal husbandry. The FC14 has the following controls: 1. Ventilation control 2. Heating control 3. Thermal control The FC14 also has a curve (see chapter 5). 3.2 Ventilation control The FC14 can be used with various ventilation systems. Fancom will first describe these systems before explaining how the ventilation control works. 3.2.1 Ventilation systems 1. ProFlow

The Fancom ProFlow ventilation system regulates the fan with the triac and the vortex damper with a 10–0V output. The FC14 automatically calculates the vortex damper position to prevent any irregular ventilation. If there is no wind influence, the FC14 opens the vortex damper. The fan runs with the lowest possible energy consumption. If the natural thermals present are sufficient to provide the required level of ventilation, the fan will deactivate.

Working

2. NatuFlow The Fancom NatuFlow ventilation system is a combination of natural and mechanical ventilation. If the natural thermals present are sufficient to provide the required level of ventilation, the fan will deactivate. The vortex damper regulates the volume of air. If the natural thermals fail to provide the required level of ventilation, the fan will activate. The controller achieves the correct volume of air using the vortex damper and fan control (triac–control). It continually checks the level of ventilation using the airflow transmitter. NatuFlow ventilation control always ensures the correct levels of ventilation, even with wind influence.

3. EasyFlow With the Fancom EasyFlow ventilation system, a fan with direction sensitive RPM feedback regulates ventilation.

4. CentralFlow/CentralControl If the FC14 is used in a central air exhaust, the analog output is used for controllable inlet control.

5. Triac control with or without vortex damper The triac for fan control can also be used in combination with the vortex damper; or the vortex damper of the Fancom ATM–unit. To set the vortex damper, see 3.2.2.1.

6. Analog control with or without vortex damper Fancom allows other types of power units to be used. For example, control of a frequency controller. A vortex damper or air inlet can also be controlled. To set the vortex damper, see 3.2.2.1.

7. Air inlet control One of the analog outputs can be used to control an air inlet. See 3.2.2.1.

8. Activating fans (Combi-control) With the FC14 one or more fan groups can be activated on the controllable part. At the moment the fans are activated, the main group will run slower. Both fan groups will displace just as much air and control to 100%. This avoids a jump in the capacity.

Working

3.2.2 Ventilation control The ventilation control ensures there is always a settable minimum amount of fresh air. If the temperature in the house becomes too high, the controller will provide extra ventilation. Use Start temperature ventilation to set the temperature above which ventilation will increase. Set the extent of the increase using Bandwidth. The increase is limited by the set Maximum ventilation, usually 100%. Control is with or without feedback. Feedback can be the RPM of the fan, or better, an airflow measurement. An airflow transmitter measures the volume of air. With control using feedback the controller will give an alarm if ventilation fails or differs too much from the calculated ventilation. If the Direction Sensitive RPM feedback (DSR feedback) fails, the controller will automatically switch to control without DSR feedback, until the DSR feedback is operational again. With a control without feedback the readout is the calculated capacity between 0% and 100%. With a control with feedback the measured percentage of the total controllable capacity is shown on the display. If the controller does not activate a fan, the readout of the measured percentage will correspond to the fan RPM or the airflow measurement. 3.2.2.1 Combi-table The Combi–Table is a kind of guide where the installer sets the relationship between controllable ventilation, additional fan(s) and the air inlet for the entire course of temperature development. At a certain temperature the FC14 will calculate a ventilation position using Start temperature ventilation and Bandwidth. Using this calculated ventilation position the FC14 determines the corresponding value for the controllable part, additional fan(s) and the air inlet.

Working

Example CombiTable As an example we will take a house with one controllable fan, two extra fans and one air inlet. At a calculated ventilation percentage up to and including 90% the controllable fan is linear controlled between 1 and 100%. The air inlet is linear controlled between 1 and 90%. At 95% ventilation, the first extra fan will activate and the air inlet will open to 95%. At 100% ventilation the second extra fan will activate and the air inlet will open to 100%.

Working

3.2.3 Influences The outside temperature can automatically influence ventilation (bandwidth) for further optimization. If it is cold outside and the controller must ventilate more, less outside air is required than if it was warm outside. The FC14 automatically widens the bandwidth with low outside temperatures. After a hot summer day, excessive ventilation in the evening and at night is often undesirable; this causes big temperature fluctuations and draughts. The automatic bandwidth increase after a long period of high outside temperature ensures that cooling is gradual. The influences can be set to apply or not.

+ The installer makes this setting. 3.3 Heating control The heating control ensures it does not become too cold in the section. If the temperature drops below the set value, the computer will make a correction. 3.4 Thermal control Thermal control, based on a set temperature, can be used for extra control if it is too cold (heating) or too warm (cooling). The measured temperature can be the same temperature as for ventilation and heating. It may also be the temperature of a separate sensor, for example: floor heating, pre-heating central corridor or creep heating.

Curves

5. Curves 5.1 What is a curve? A growing animal requires a different optimal temperature from day to day. The ventilation, particularly the minimum ventilation, must “grow” with animals. The user each can decide this pattern of development for each day, week or month by setting a different temperature, minimum and/or maximum ventilation. Once you know the animal growth pattern on your own farm it can be handy to enter this data in the computer. The FC14 will then automatically ensure the correct settings from day to day or even from hour to hour. Fancom calls this process the curve. Example: Enter the required temperature and the minimum/maximum ventilation values for a number of days in the cycle. These days in the cycle have a number, the day number. For the day number use, for example, the age of the animals (piglets) or the number of days the animals have been in the section (fatteners). For example, enter the required values for days 1, 50 and 150. The controller calculates the correct values for the days in between. Fancom calls these 'in-between' days the bending points. A bending point consists of a day number and a number of settings for temperature, minimum and maximum ventilation. Fancom will explain how a curve works using the following values.

Table 1: Example of a curve

Curves

The controller calculates for day 100 in the cycle that Start temperature ventilation should be 20.0°C. Day 100 is precisely between day 50 and day 150; Start temperature ventilation is also precisely between 21.0°C and 19.0°C. When the bending points for your situation have been set, all you have to do is enter the day number. The day number indicates where the computer must look in the curve. Day number The day number is a counter increased by the controller each day at midnight by one up to a maximum of 999. If the day number is 0 it will not change. The FC14 then controls without the curve, even if the bending points have been set. If a curve is used, the day number is the basis used to calculate the setpoints from the relevant curve. If a negative day number is set, the FC14 will control without using the curve, until the day number is a positive number. A negative day number is also increased at midnight by one, except the jump from day –1 to day +1 (a jump of 2).

+ A correct day number setting is very important if curves are used.

Empty settings F curve control is used, the following is important. If a section is unoccupied set the day number to 0 (or a negative number). The FC14 will remember the climate settings entered, the empty settings. In the next cycle curves are used again. Next time the section is empty all you have to do is set the day number to 0. The FC14 will control based on the empty settings.

5.2 Setting the curve There are 10 bending points. At a bending point start by entering the day number; the settings at this bending point apply to this day number. Then make the settings for the following keys: Heating Start temp. ventilation

Bandwidth

Minimum ventilation Maximum ventilation Thermal control Set the day number to 0 for all unused bending points. If the curve is used, all settings above must be included in the curve. Entering bending points 1. Press Enter curve. CUR. will appear on the display 2. Press . The first bending point (left field display) with

corresponding value (right field display) of key Day number will automatically appear on the display; the bending point–number (left field display) will flash.

3. Enter the day number (1) for bending point 1. 4. Press Heating. The value 1 is still flashing in the left field of the

display. This indicates that the setpoint heating for the first bending point is being set. Enter the required heating value (in the example 23.0).

5. Enter the required values for the other options in the same way:

Curves

6. Press to select the next bending point. The flashing bending point number in the left field of the display will increase by one. Use to select the previous bending point.

7. Select bending point 2 and select Day number again. Repeat steps 3 thru 6 for each bending point (in the example bending points 2 and 3).

8. Press Enter curve to finish setting the bending points. You can now operate the FC14 normally again.

Actual day number If you press Day number immediately without first confirming Enter curve, the actual day number will appear on the display. If the actual day number is a value higher than 0, the controller is controlling according to the set curve(s). Each night at midnight (0:00 hour) the controller increases the day number by 1. If the day number is 0, the controller is not controlling according to the curve(s), but using the settings made by the user. These settings are saved, even if a curve is used. This allows your settings (if Day number = 0) to be used as empty settings. During a cycle the controller controls according to the curve settings. At the end of the cycle, set the day number to 0 and the controller will control using the "Day number = 0" setting (empty setting). The day number can also be set as a negative value. The controller will control without the curve as long as the day number is negative. The controller will increase a negative day number by 1 each midnight, except for the jump the day number makes from –1 to 1. After this jump, the controller will control again according to the set curve.

+ If the day number is set to 1, 0 or a negative value, all the curve–offsets will also be set to 0. This prevents any unwanted offsets being active when the house is empty or new animals are being set up.

Curves

5.3 Offset If curves are used, it is sometimes necessary to make small adjustments to the setting calculated by the controller. These are usually temporary adjustments. Do this by just changing the settings. The FC14 remembers by how much the settings were changed. If you want to know later what has been changed or you want to undo the changes, use option OFS (offset = difference). Method 1. Press Enter curve. 2. Use or to select Offset–mode (OFS). 3. Press . The correction value (offset) of key Heating

automatically appears on the display. 4. Press the key (for example Minimum ventilation) to be corrected. 5. Read out the correction value and set to e.g. 0.0. 6. Press Enter curve to quit Offset–mode . You can now operate the

FC14 normally again.

+ If the adjustment is not temporary, it is better to adjust the curve instead of the settings.

Enter the Setpoint heating. The controller controls the heating based on the average value of the sensor and extra sensor. If the extra sensor has not been connected, the controller will control based on the measured value of the sensor.

+ For extra security Setpoint heating cannot be set higher than the Absolute maximum alarm (key ). If the setting is made too high, the controller will make the setpoint equal to the absolute maximum alarm limit.

+ If there is a high outside temperature influence on start temperature ventilation, the same shift will also apply to Setpoint heating (see Start temperature ventilation).

Start temperature ventilation (Range = 0.0°C ... +99.0°C) (Factory setting= 20.0°C and no outside temperature influence)

Enter the temperature above which ventilation must increase. If the temperature is lower than this setting, the calculated ventilation equals the Minimum ventilation. If the temperature becomes higher than the set Start temperature ventilation, ventilation will increase. The ventilation can increase up to the set value maximum ventilation (100% or less). The temperature rise from minimum to maximum, is called the Bandwidth.

High outside temperature influence A high outside temperature can influence start temperature. If the outside temperature rises above the set start temperature ventilation and ventilation is maximum, Start temperature ventilation will be increased. If the outside temperature drops below the set Start temperature ventilation, the controller will decrease the influence within the set number of hours until it reaches the set start temperature ventilation.

If is pressed, any start temperature ventilation influenced by the outside temperature will appear on the display first.

+ The same shift that applies to start temperature ventilation also applies to setpoint heating. If the thermal control has been assigned to the room sensors, this control will also be influenced. The increase depends on the settings made by the installer. If the factor has been set to 2.0, the maximum influence equals the bandwidth.

A low or high outside temperature can influence the bandwidth. The influence depends on the settings made by the installer. High outside temperature influence If the outside temperature rises above Start temperature ventilation and ventilation is maximum, the bandwidth will increase. If the outside temperature drops below the Start temperature ventilation, the controller will decrease the bandwidth within the set number of hours until it reaches the set bandwidth.

Minimum ventilation (Range = 0 … 100%) (Factory setting = 50%)

Ventilation is minimum if the measured temperature is equal to or lower than Start temperature ventilation (key ). If several fans are used set the required minimum ventilation based on the total installed capacity. This means that with two identical fans the minimum RPM of the first fan will be double the capacity set here. Example: Minimum ventilation = 10%.

The minimum RPM of the fan will be 20%, as this is 10% of the total capacity.

+ Correct control of minimum ventilation is essential for good management. Too low minimum ventilation will cause the air quality in the house to deteriorate. A too high minimum ventilation position on the other hand will extract too much heat. This heat will have to be added again, either by heating, or by extra feed consumption by the animals (if the section temperature drops too low). Correct settings are very important!! The controller must also be able to achieve these settings. This is only possible if the controller can continually measure the actual fan RPM (via RPM feedback), or even better, the actual volume ventilated (via airflow transmitter). Precisely controlled ventilation (independent to chimney draughts or wind influence) can be achieved using the Fancom ProFlow system.

Ventilation (capacity%) (Range = 0 … 100%)

Readout of the current ventilation position. If the computer does not measure ventilation, this is the calculated ventilation. In other cases the measured ventilation appears immediately after the calculated ventilation. If several fans are used the percentage of the total capacity is shown. The controller assumes that all fans are controlled. Press or key to briefly show the calculated ventilation on the display again. Depending on your ventilation system, the measured ventilation may not be indicative of the total ventilation. The installer has set that measured ventilation only concerns controllable ventilation. The calculated controlled part, the measured control part and the calculated ventilation will appear successively on the display. Press or key to briefly show the calculated and measured control part on the display again. If the measured RPM (fan or airflow transmitter) is higher than the calculated ventilation position, the controller will decrease ventilation control to the calculated ventilation position. If ventilation control is minimum and the RPM (fan, airflow transmitter) remains too high for one minute, the controller will give a maximum RPM alarm (if set). If the FC14 measures the RPM or air volume, it will give a minimum ventilation alarm if ventilation control is maximum and the measured value is lower than the control value. If the FC14 notices that RPM feedback is not functioning, it will automatically switch to control without RPM feedback. The following will appear on the display:

Thermal control (Range temp. therm. ctrl. = –9.9 … +99.9°C) (Range therm. ctrl. setting = 0.0 … +99.9°C) (Factory setting = 18.0°C)

If thermal control uses the same sensor as the ventilation control and the installer has set a high outside temperature influence on start temperature ventilation, the thermal control setpoint will also be influenced. If is pressed, the influenced thermal control setpoint will appear on the display, followed by the set setpoint thermal control.

+ For extra security the setpoint thermal control cannot be set higher than the absolute maximum alarm (key ). If the setting is made too high, the controller will make the setpoint equal to the absolute maximum alarm limit. The security measure above does not apply if the installer has switched off the alarm on the thermal control sensor (sensor 3).

Outside temperature (Range = –30.0 … +150°C)

On hot summer days the temperature in a section can be very high. This can result in a maximum alarm or the difference alarm will have to be set high. This is not desirable with lower temperatures; the maximum alarm limit would then be unnecessarily high. In order to provide effective alarms (max. difference alarm as small as possible) the computer increases the alarm limit parallel to the outside temperature, as soon as this is higher than the point at which ventilation is maximum. Example 2

Calc.start temp.ventilation 20°C Calculated bandwidth 4°C + Ventilation is maximum at: 24°C Setpoint therm.ctrl. 24°C Outside temperature 25°C (Max.) difference alarm 3°C + Max.difference alarm 3°C + Calculated alarm limit 28°C Calc. alarm limit 27°C An alarm will occur if a temperature becomes higher than the maximum alarm limit: 25+3=28°C.

On hot summer days certain conditions (for example storms) can cause the outside temperature to suddenly drop. The alarm limit will drop accordingly. However, the temperature in the building will not usually drop as suddenly. Normally this would result in a max. difference alarm. In this case the alarm limit will drop with a delay and the computer will check if the section temperature also drops. The maximum difference alarm for thermal control can also be used without outside temperature influence. The installer makes this setting (SYS.2).

Minimum difference alarm (Range = 0.0 … +25.5°C) (Factory setting = 3.0°C)

A minimum difference alarm can be set for temperature and thermal control temperature (if a sensor is connected and assigned). If Min. difference alarm is pressed, the LED in this key will illuminate as well as the LED in Temperature or Thermal control. Press again to select the right temperature. After key has been selected, the calculated minimum alarm limit will briefly appear on the display followed by the minimum difference. This is the set number of degrees the temperature may drop below Setpoint heating or Setpoint thermal control. An alarm will be given as soon as the measured temperature becomes lower than the minimum alarm limit. Example: Setpoint heating/thermal control

Min. difference alarm 20.0°C 4.0°C

Calculated minimum alarm limit 16.0°C

An alarm will occur if the temperature becomes lower than 16.0°C.
