5 Configuration of Analog Inputs

Only authorized staffs can access the “IO” parameter group categorized under the menu and configure analog inputs. It is recommended to configure all the parameters and values in Stop Mode of the controller. When connecting the devices with the terminals(X1…X6) for analogue inputs, please configure all relevant parameters to make sure that sensors can work properly. The main steps are as follows: • Selection of analog input signals • Selection of sensor types • Configuration of DIP switches • Configuring analogue inputs as digital inputs (ON/OFF) • Setting validity of analogue inputs (Configured as Digital Inputs) For example: To configure terminal X1 to measure condenser pressure, do the following: • Go to _ _IO14, and set IO14 = 4 (condenser pressure). • Then, navigate to IO27 and indicate the type of pressure sensor by selecting a value

from the range 1 to 14

14.2 Defrost Control

In heating mode, press the <Minus> button for 2 seconds to start manual defrost if all related parameters are configured. Automatic defrost can only be started when all relevant parameters, such as defrost method and logic, are configured, and the system and the compressor has been running for certain period (DF17 and DF18). Defrost logic with their descriptions are as follows: • Defrost with timer (when DF04=0): the delay time between two defrost requests is

equal to or greater than the preset time (DF11). • Defrost with timer and temperature/pressure (when DF04=1): the referred

temperature (via DF05) remains less than or equal to the defrost start point (DF06) after the delay time (DF08).

• Defrost with the differential value between defrost temperature and outside temperature (when DF04=2): the measured outside temperature is less than the preset setpoint (DF16), and the actual differential value between defrost temperature (via DF05) and outside temperature (?) is equal to or greater than the setpoint (DF15) after the delay time (DF08).

When one of the defrost conditions above is reached, the system will start defrost based on the defrost method you configured: • Fan defrost (DF02=1) • Hot gas bypass (DF04=0) • Reversing valve (DF04=1) First apply the method of fan defrost if it is enabled and if the actual outside temperature is equal to or greater than the preset point (DF14). Otherwise, apply one the other two methods (DF04=0, 1).

Notes

41/56


The defrost process, either automatic or manual, will stop when either of the following conditions is reached: • The referred temperature (via DF05) is greater than the end point (DF07) and the

defrost process lasts for DF09. • Or, the defrost process lasts for DF10. Each of the defrost processes above will end after the preset minimum duration (DF09) if it is manually stopped. At the end of defrost, the fan will be activated at maximum speed to ventilate the condenser for the preset time (DF13). Except for manual defrost, the delay between two automatic defrost processes must meet the preset delay time (DF11).

14.3 Energy Savings and Comfort Conditions

In RWR470.10, two methods of energy savings are provided: • The controller temperature setpoints are automatically compensated according to

outside temperature (herein called Economic Cooling/Heating Function). • Fixed shifts of controller setpoints (herein called Economy Mode)

14.3.1 Economic Cooling/Heating Function

When the system works in Economic Cooling/Heating Function (enabled when SF05=1), the system will automatically adjust the controller setpoints according to the outside temperature. This adjustment can save energy and create comfort conditions as the outside conditions vary. The controller setpoint(s), ST01 for cooling mode and ST02 for heating mode, will be automatically adjusted according to the actual outside temperature. In cooling mode, necessary parameter settings are as follows: • Controller setpoint (ST01) – the setpoint that the system should arrive in normal

working mode • Controller setpoint shift value (ST10) – the range of controller temperature setpoint

shift • Outside temperature setpoint (ST08) – the outside temperature setpoint to start the

energy saving program (if configured ) • Outside temperature shift value (ST09) – the range of outside temperature setpoint

shift

In heating mode necessary parameter settings are as follows: • Controller setpoint (ST02) – the setpoint that the system should arrive in normal

working mode • Controller setpoint shift value (ST13) – the range of controller temperature setpoint

shift • Outside temperature setpoint (ST11) – the outside temperature setpoint to start the

energy saving program (if configured ) • Outside temperature shift value (ST12) – the range of outside temperature setpoint

shift

14.3.2 Economy Mode

When Economy Mode is configured (when SF06=1), the system will run in the newer setpoints (ST06 / ST07) instead of the previous ones (ST01/ST02) once this mode is activated via a digital input or menu-driven operation.

Once the Economy Mode is running, the symbol “ ” will be lighted. Economy Mode will be automatically set to OFF upon power failure. Applying power to the controller again needs to re-activate the Economy Mode.

Notes

43/56


14.4 Antifreeze

(Currently, the system refers to the air-to-water application) To activate the antifreeze function, the following prerequisites must be reached: • The controller remains in Stop Mode (power ON yet). • Antifreeze function (SF04) is enabled. • Sensor for outside temperature is configured (CN09=1) Under the conditions above, when the actual supply temperature or return temperature (determined via SF07) is equal to or less than the differential value between antifreeze setpoint and temperature band (SF11 – SF12), and the actual outside temperature (via CN09) is lower than the setpoint (SF13), the pump will be switched on, and a warning (code: WN02) will be displayed on the LCD, flashing continuously. In the meantime, if the feedback signal of flow switch (digital input) from pump ON (only when EV01=0 or 1) is okay within the preset time (AL08), the antifreeze process will be activated. Otherwise, an alarm (code: AL34) will display. Only after the supply temperature/return temperature is greater than the antifreeze setpoint (SF11), the E-heater (If configured) will be stopped, and the pump will be switched off after the delay (CM07).

14.5 Forced Adjustment Management

Forced Adjustment Management is only applicable for the cooling mode of the system. This function is to adjust the condensing pressure/temperature by reducing compressor stages. The Forced Adjustment Management, if configured (SF02) and activated, has priority over the control of compressor capacity stages. That is, if all conditions for Forced Adjustment Management are reached, the system will apply the control logic of Forced Adjustment Management only. Once the actual condensing pressure / temperature (determined via CN08) is equal to or greater than the pressure/ temperature setpoint (CN03/CN02), but less than the pressure / temperature setpoint for alarm (CN05/CN04), the system will start adjusting the condenser pressure/temperature by the following methods: • First reducing the compressor stage from Stage 3/ Stage 4 to Stage 2, if applicable; • Or, reducing the compressor stage to Stage 1 after the delay time (SF08), if the

current stage is Stage 2; • If the actual pressure/temperature falls down to the differential value between

setpoints for alarm and pressure/temperature band for alarm (CN05–CN07/CN04 –CN06), the Forced Adjustment Management will be stopped.

• Or, an auto reset alarm (alarm code: AL00) will be generated after the delay time (SF09) if all methods utilized failed to reduce the condensing pressure /temperature down to the differential value between setpoint for alarm and pressure/temperature band for alarm (CN05-CN07 / CN04-CN06).

• If the actual condensing pressure/temperature is equal to /greater than the pressure /temperature setpoint for alarm (CN05/CN04), the Forced Adjustment Management

Notes

44/56


will be skipped over, and an auto reset alarm (alarm code: AL00) will be displayed directly without any delay.

A warning (code: WN10) will be displayed when the actual condensing pressure is greater than the start point for Forced Adjustment Management, but less than the setpoint for alarm.

14.6 Pump Down

The Pump Down function can only take effect in the cooling only or heating only system. The Pump Down function is to drive almost all refrigerant into the condenser before turning off the compressor. It protects the compressor from sucking the liquid refrigerant. To make this function work, you need activate this function (via SF03) and configure all relevant parameters. If the system is stopped from normal working mode, the SV will be first closed, and the compressor will continue working until the preset delay time (SF10) expires. When the pump down process is performed during the system stopping process, the

icon will flash continuously until the pump down process is finished. Except for low pressure alarm, if any other alarm is detected and displayed on the LCD in the pump down process, the system will return to the normal working mode after the alarm is reset. Pump down will not be performed either in the defrost process or under the situation that any alarm except for low pressure is existent.
