General
System description
GeneralEVC 13 has outdoor temperature controlled boiler temper-ature, which is why a shunt valve is not needed. Outdoortemperature sensor supplied. The power is connected anddisconnected using two contactors and two relays.
EVC 13 has an integrated circulation pump, expansionvessel, safety valve, drain valve, load monitoring input forcentralised load control.
Current regulations require the heating installation to beinspected before it is commissioned. The inspection mustbe carried out by a suitably qualified person and shouldbe documented.
The above applies to electric boilers with a closed expan-sion vessel. If the boiler or the expansion vessel is replaced,the installation must be inspected again.

Heating control systemThe indoor temperature depends on several differentfactors. During the warmer times of the year, solar radi-ation and heat given off by people and equipment aresufficient to keep the house warm. When it gets colderoutside, the heating system must be started. The colderits gets, the hotter the radiators need to be.

Heating curve offset
This adjustment is made automatically, however the correctbasic settings must first be made on the boiler (see below).
Default settingThe basic heating is set with the “Heating curve selection”knob and with the “Offset heating curve” knob. If you donot know the correct settings use the basic data from themap opposite. If the required room temperature is notobtained, post adjustment may be necessary
NOTEWait one day between settings so that the temperat-
ures have time to stabilise.
Post-balancing adjustment of the default setting.
Cold weather conditions
If the room temperature is too low, increase the “Heatingcurve selection” setting by one step clockwise.
If the room temperature is too high, reduce the “Heatingcurve selection” setting by one step anti-clockwise.
Warm weather conditions
If the room temperature is too low, increase the “Offsetheating curve” setting by one step clockwise.
If the room temperature is too high, reduce the “Offsetheating curve” setting by one step anti-clockwise.
Changing the room temperature
Changing the room temperature manually
If you want to temporarily or permanently lower or raisethe indoor temperature relative to the previously settemperature, turn the “Offset heating curve” knob anti-clockwise or clockwise. One line approximately representsa 1 degree change in room temperature.
Changing the room temperature with time controls
Use the "Night reduction" knob to increase or reduce theroom temperature at certain times of day. The start posi-tion for this knob is 0. A change of one corresponds toapproximately 1 degree change in room temperature. Thechange is active during the times that you have set on theclock (see section“Programming of clock" on page 10).
NOTEAn increase in the room temperature may be ”inhib-ited” by the radiator or under floor heating thermo-
stats, if so these must be turned up.

Example
The values stated on the map apply for “Heating curve selection”.
The first value applies for low temperature radiator systems. Ifyou have a high temperature radiator system the stated valueshould increase by 3 units. In both cases the “Offset heatingcurve” is set to -2.
The value in brackets refers to under floor heating systems. Inthis case the “Offset heating curve” is set to -1.
The map values are usually a good starting point and concernan approximate room temperature of 20°C. The values can beadjusted later if necessary.
Examples of default values selection1. Houses with low temperature* radiator systems:
Markaryd = Area 10 (5). Set 10 on the ”Heating curve selec-tion” knob and -2 on the ”Offset heating curve” knob.
2. Houses with high temperature** radiator systems:
Markaryd = Area 10 (5). Set 10+3=13 on the "Heating curveselection" knob and -2 on the "Offset heating curve" knob.
3. House with under floor heating***.
Markaryd = Area 10 (5). Set 5 on the "Heating curve selection"knob and -1 on the "Offset heating curve" knob.
* A low temperature radiator system refers to a system where the supply temperature
needs to be 55 °C on the coldest day..
** A high temperature radiator system refers to a system where the supply temperature
needs to be 70 °C on the coldest day.
*** Under floor heating can be dimensioned very differently. Example 3 above refers
to a system where the supply temperature needs to be approximately 35–40 °C on
the coldest day.

Setting after diagramEVC 13 is equipped with an outdoor temperature con-trolled heating control system. This means the boilertemperature and therefore the supply temperature isregulated in relation to the current outdoor temperature.
The relationship between outdoor temperature and supplytemperature is set with the “Offset heating curve” and“Offset heating curve” knobs.
First, select "Offset heating curve". A suitable value forunder floor heating is -1 and for a radiator system -2.
The diagram is based on the dimensioned outdoor tem-perature for the area and the dimensioned supply temper-ature of the heating system. When these two values“meet”, the heating control's curve coefficient can be readoff.

Programming of clockThis programming is done to determine what times nightreduction is to be activated. The clock is programmed asfollows:■ Press the “Day” key until the day you want it shown in
the display.■ Program the desired time for night reduction by pressing
the buttons, which are placed around the clock display.The numbers around the display indicate the 24 hoursof the day.
One press: Night reduction activated the full hour.
Two presses: Night reduction activated in the first halfhour.
Three presses: Night reduction activated in the secondhalf hour.
Four presses: Night reduction deactivated the full hour.■ Select a new day with the “Day” key, and repeat the
previous procedure.■ When programming is completed press the ”Day” button
for the current day.
The clock can also be programmed in 15 minute intervals.Start by selecting the desired half hour where the 15minute activation is desired. Press the same segment but-ton again, and hold it in. By pressing the ”15” button inthis mode the desired 15 minute interval can be selected.The clock can also be operated manually (not normallyused). This is done as follows:■ Press the button, and keep it pressed in or 3 seconds.
The relay will switch off and OFF will start to flash.■ Press the button and the relay will shift between on
and off, ON/OFF will flash all the time.■ To return to automatic press the button again and
keep it pressed for 3 seconds. ON/OFF indication willnow light constantly.
Night reductionThis setting is used to change the heating during certainperiods during the day and night.
Night reduction is activated by the timer. The mode is se-lected using the switch (25).
The clock's programmed on/off determines the timeswhen the supply temperature should change to give achange of room temperature. ON indicates night reductionon. OFF indicates night reduction off.
If a reduction in the temperature is required, the value isreduced using the “Night reduction” knob. If an increasein the room temperature is required, the value is increasedusing the "Night reduction" knob. The setting range is -10to +10. One step change gives approx. 1 degree changein the room temperature.
NOTENOTE! An increase in the room temperature may beinhibited if the thermostats for the radiators or underfloor heating are set too low, if so these must be
turned up.
If you want to temporarily or permanently change theroom temperature the "night reduction" switch can beused in addition to the manual on/off on the clock. Thebutton switches between ”Constant day", Constant night”and ”Automatic” modes. See section "Front panel" on page5.

Monitoring and maintenance
Max. thermostatTo access the max thermostat and the breaker for the tariffcontrol the front hatch must be opened. The max thermo-stat is set to limit the max boiler/supply line temperaturefor the heating system. Suitable setting is approx. 10 °Cabove the dimensioned supply temperature. This is espe-cially important for under floor heating, to prevent damageto the floor covering.
Tariff control, (option)With the switch pressed so that the red marking is visible,the external water heater is always powered via EVC 13regardless of external control.
Safety valveThe front hatch must be opened to access the safety valve.Turn the button anticlockwise and open the hatch.Manually open and close (turn the knob a click anticlock-wise) the safety valve approx. four times a year, at whichtime check that a small amount of water flows out andthat the valve seals closed. After the checks, ensure thatthe system has the required pressure. If necessary top upwith water. This is done using the hose via the drain valve(51) or via the filler valve fitted by the installer, see thesection ”“Commissioning and adjusting” – “Filling".

Pipe installation
Transport and installationThe electric boiler must be transported and stored dry.EVC 13 is designed to be positioned on top of an electricwater heater of the NIBE COMPACT type. Ensure that anyanode in the water heater is accessible. For installationand access for service, there must be space of approx.30 cm above and approx. 60 cm in front of the boiler.
NOTEEVC 13must be installed horizontally, at least 50 cmfrom the floor. To ensure sufficient ventilation for theelectric components, there must be an air gap of atleast 10 mm under the bottom plate of the boiler.
ConnectionsPipe installation must be carried out in accordance withcurrent norms and directives. The boiler is equipped withR20 connections, externally threaded. Shut off valvesshould be installed outside EVC 13 to simplify any futureservice.
NOTEThe pipe installation must be flushed, so that anycontaminants do not damage the equipment.
Overflow pipeThe overflow pipe must be routed according to currentnorms and directives.
The overflow pipe from the safety valves must be routedto a floor drain to prevent hot water splashes whenchecking the valves or when bleeding the boiler. The outletof the overflow pipe must be visible.
When installing a NIBE COMPACT water heater, the over-flow pipe for the electric boiler must be routed straightdown through the top panel of the water heater.
Tapping valveEVC 13 is equipped with a drain valve (51) on the boilerwith a R15 ( 1/2” ) hose connection. To drain the boiler,remove the cap for the valve and screw the hose connec-tion into position. Open the drain valve. The safety valve(52) is then set to the open position for air supply. Thedrain valve for the radiator system must be located in asuitable place.
Circulation pumpThe boiler has a circulation pump located in the returnline. The pump capacity is set using the diagram. To pre-vent cavitation in the pipes the flow must not exceed 1700l/h.

Expansion vesselThe expansion vessel (85) volume is 12 litres and has a pre-pres-sure of 50 kPa (0.5 bar) as standard. This means that the maxim-um height (H) between the vessel and the highest situated radi-ator is 5 m, see the figure to the side.
If the standard pre-pressure in the pressure vessel is not highenough it can be increased by adding air via the valve in the ex-pansion vessel. The pre-pressure of the expansion vessel mustbe stated in the inspection document. Any change in the pre-pressure affects the ability of the expansion vessel to handle theexpansion of the water.
If the heating installation has an open expansion vessel, the dis-tance between the highest radiator and the expansion vesselmust not be less than 2.5 m.

Power control immersion heater
The boiler temperature is controlled by the outdoor tem-perature. The control equipment connects power in stepsof 1 – 2 kW and controls itself in the relevant power range.Restriction of the power is set using the ”Power restriction”potentiometer, see image. To maintain an even supplytemperature, the stepping is time limited to 3-4 minutesper power step.

Centralised load control/load monitor
If centralised load control or load monitor is used the HPpipes for signal cables must be routed to the boiler. Theload monitor is set using the ”Fuse size" potentiometer,see section "Power control immersion heater" on page 18.Connection of the load monitor current sensor is made onthe terminal block (14) pre Safety Extra-Low Voltage (SELV),see image. Centralised load control is connected usingpotential free connections on the same terminal block.

Max thermostat/Temperature limitationIn normal operation, the boiler's supply temperature isrestricted by the ”Temperature limitation” potentiometer,see image in section”Power control immersion heater”.Normal setting is approx. 5 °C above the dimensionedsupply temperature. In addition to the setting for ”Temper-ature limitation” there is also a ”Max thermostat”, whichalso has the task of ensuring the limitation of the supplytemperature. Normal setting is approx. 10 °C above thedimensioned supply temperature. During operation in R-mode, the supply temperature can be adjusted using themax thermostat.

The signal from the outdoor temperature sensor controlsthe control centre so that the correct boiler/supply tem-perature is obtained. The relationship between outdoortemperature and boiler/supply temperature is set withthe "Offset heating curve" and "Heating curve selection"knobs. The outdoor temperature sensor is normally locatedon the north or north west wall, well protected frommechanical effects. The sensor must measure the correctoutdoor temperature and must therefore not be affectedby the morning sun, for example. Electrical connection ismade to the relay card (29) terminal block (14). If a conduitis used it must be sealed to prevent condensation in thesensor capsule. The minimum cable cross section shouldbe 0.4 mm2 up to 50 metres, for example, EKKX or LiYY.
Temperature limiter
The temperature limiter (6) cuts off the power supplybetween 90 – 100 °C and can be manually reset by pressingthe reset button, see section ”Resetting the temperaturelimiter" on page 14.
Boiler/Supply temperature sensor
Boiler/Supply temperature sensor (18), see section "Com-ponent positions" on page 25, measures the supply tem-perature and sends a signal to the automatic heatingcontrols, which in turn corrects the supply temperatureusing the immersion heater.

FillingThe filler connection (79), 15 mm copper pipe, is connectedto the system's fresh water pipe. When filling the heatingsystem, the filler valve (49) is opened, whereby the systemis filled with water. Observe the pressure rising on thepressure gauge. When the indicator reaches 2.5 bar, thesafety valve opens (52) and starts to release air mixed withwater. Stop the filling. Turn the safety valve until the boilerpressure reaches the normal working range (0.5-1.5 bar).
VentingThe boiler is vented through the safety valve (52). The restof the heating system is vented through their respectivevent valves.
NOTEThe safety valve must be operated very carefully be-
cause it opens quickly.
Secondary adjustmentAfter venting is completed the pressure must be adjusted.Suitable pressure is approx. 1.2 bar if the system is hot andapprox. 0.6 if the system is cold. Air is initially released fromthe hot water and venting may be necessary. If gurglingsounds can be heard from the boiler, the entire systemrequires additional venting. When the system is stable(correct pressure in the boiler and all air eliminated) theautomatic heating control system can be set as required.See section "Heating control system" on page 7 and“Front panel" on page 5.
