System description
Principle of operation
EVP 270 is an electric boiler designed for houses with water-borne heating. The electric boiler consists of a pressure vessel,two immersion heaters and intelligent controls. The vessel’slower part contains a mixing chamber that provides the beststratification and temperature flux when docked to a heatpump.
Water is heated using a finned coil of copper.
The immersion heaters have a max output of 13.5 kW withthe option of setting lower outputs. The factory setting is10.5 kW.
The boiler temperature is variable, which provides economicaloperation and permits connection to high-temperature sys-tems.
The total water volume is 270 litres.
EVP 270 is delivered with a bivalent shunt so that the righttemperature is obtained in the heating system with big sav-
ings. The flow temperature is determined by the currentoutdoor temperature and settings.

Room temperature
Heating control system
The indoor temperature depends on several factors. Duringthe summer season, solar radiation and heat given off bypeople and equipment are sufficient to keep the house warm.During this period, you can turn off the circulation pump(see section "The front panel’s lower (concealed) part", pointH, on page 5).
When it gets colder outside, the heating system must bestarted. The colder its gets, the hotter the radiators need tobe. This adjustment is automatic, however the boiler mustfirst be given the correct default settings (see the section"Default setting").

Setting of hot water temperature
The boiler temperature is set at 50°C.
This normally provides a good combination of savings andcomfort.
If you want to increase the hot water capacity (comfort level),raise the temperature in the upper section of the boiler.
If you want the heat pump to provide an even greater pro-portion of the heating, you should reduce the temperaturein the upper part of the boiler. This reduces the comfort level,but increases savings.
These settings are done in channel 9.

Maintenance routinesThe boiler requires some regular maintenance. Please followthe points below.
Checking the safety valves
EVP 270 ,must be provided with two safety valves when in-stalled; one for the heating system and one for the waterheater.
The heating system’s safety valve must be completely tight,but the water heater’s safety valve may occasionally releasesome water after hot water has been used. This is becausethe cold water, which enters the water heater to replace thehot water, expands when heated causing the pressure torise and the safety valve to open.
The safety valves must be checked regularly. Check as fol-lows:
Open the valve.
Check that water flows through the valve.
Close the valve again.
Check the pressure. If the pressure is too low, top up theboiler water.
Control of the heat pump
We recommend regular checks of the heat pump’s status,since disruptions to the normal operation of the heat pumpwill not result in any changes in the perceived comfort level,as immersion heater mode will automatically take over.
Pressure gaugeLEK
Pressure gauge is to show the pressure in the heating system.See section “Commissioning and balancing" on page 21.
In a closed system, the pressure varies with changes in tem-perature in the boiler and heating system – high temperatureswill increase pressure. Do not add water before the pressurehas stabilised at a level lower than the expansion vessel’sinitial pressure (normally 0.5 bar).
In an open system, the pressure depends on the height dif-ference between the expansion vessel and the boiler (forexample, 5 m corresponds to roughly 0.5 bar).

Maintenance routines
General information for the installer
Transport and storage
The electric boiler should be transported and stored verticallyin a dry place.
Assembly
The electric boiler is ideally located in a utility room or boilerroom. The unit can be levelled using the adjustable feet.
If pipes are to be laid inside an internal wall that backs ontoa bedroom or living room, do not use clamp rings.
Inspection of the installation
Current regulations require that the heating installation isinspected before it is commissioned. The inspection must becarried out by a suitably qualified person and should bedocumented. The above applies to closed heating systems.The boiler may not be replaced without the installation beinginspected again.
Setting of min/max temperature levels
On delivery, the boiler, and also the finned coil have a setminimum temperature of 50°C. This level is adjustablebetween 40 and 90°C. You set this level on channel 9 usingthe increase/decrease buttons. Where the flow’s calculatedtemperature level is higher than the boiler’s set minimumlevel, the boiler temperature is automatically raised to thecalculated level. The temperature in the finned coil increasesat the same rate as the boiler temperature increases. Withthe help of a mixer valve (not supplied), you can set theoutgoing hot water temperature.
The upper temperature of the boiler can also be limited. Thisis done using the potentiometer (62) on the printed circuitcard(41) that is located behind the internal cover place behindthe front access panel. The temperature level is set in 5 de-gree steps between 60 and 90°C and can be read duringsetting and later controls/maintenance, on channel 16.
Channels 11 to 22 are service channels. These channels be-come accessible by changing the value from 0 to 1 underchannel 10.
When you press the button more times you come to channel11 and the subsequent channels. After around 20 minutesor by changing the value 1 to 0 under channel 10, the controlpanel goes back to displaying only channels 1 to 10.
In some cases, you might need to be able to set upper andlower limits for the flow temperature. You do this using theincrease/decrease buttons under channel 12 for minimumand channel 13 for maximum flow temperatures.
Start and stop of a heat pump (if used) is balanced onchannels 20-22 (see channel descriptions).
Setting of docking thermostat
The docking thermostat default setting is 51° C. To preventoperating disturbances this value may need adjusting, be-cause the outdoor air heat pump produces a high output athigh outdoor temperatures. For F20XX 8 kW, we recommenda setting of 51 °C and for F20XX 10 kW 50 °C.
Connection
Pipes are to be installed in accordance with the applicableheating and hot water standards. Internal support bushesshould be fitted when annealed steel or copper pipe is used.
The shunt is equipped with compression ring couplings.
The overflow pipe form the safety valves is to run to a floordrain so that hot water will not splash out when the valvesare checked or the boiler is vented. The overflow pipe mustslope downwards along its entire length to prevent waterpockets forming and must be frost-proofed. The outlet ofthe overflow pipe should be conspicuous.
The hot water circuit must be fitted with a mixer valve if aboiler temperature over 65°C is permitted in order to preventscalding. The supplied check valve is to be mounted in thecharge circuit to prevent natural circulation.
EVP 270 can be connected to an open or closed expansionvessel.
If the heating system is equipped with an open expansionvessel, the distance between the highest radiator and theexpansion vessel may not be less than 2.5 m.

Docking
Electrical connections F20XX
EVP 270 controls stop/start of the compressor in F20XX viathe docking thermostat.
When the docking thermostat (94) is active, a red lamp glowsin the channel select button (18).
Connect as shown in the figure below.
Suitable cable is 4 x 0.22 – 0.25, LiYY or LiYCY.
The charge pump between EVP 270 and F20XX is electricallysupplied from F20XX. This is to prevent frost damage atoutdoor temperatures under 0°C.
Accessories required
The upper immersion heater works to the set temperatureon channel 09. The lower immersion heater is blocked bythe heat pump until the heat pump is stationary.
If the outdoor air temperature drops to a level below the setvalue under channel A7, compressor operation is blocked
and all heating is provide by an external supplementaryheater. This function is also activated when F20XX is withoutpower.
Electrical connection EVP 270
To control EVP 270's immersion heater, a cable must beconnected to the electric boiler's terminal block (14) terminals"-" and "B", tariff/centralised load control. Connect thecable to terminal X201 (stationary NO and COM) inF2020/2025 and terminal X6 in F2026. Suitable cable is 4 x0.22 – 0.25, LiYY or LiYCY. The EVP 270's immersion heatercan also be blocked manually.
When the outdoor temperature drops, the entire heatingrequirement will need to be supplied by EVP 270.
On delivery, the boiler and indirectly also the water heaterhave a set minimum temperature of 50°C. The dockingthermostat’s current value can be read on channel 20.

Preparations
Check that switch (8) is in “0” position and that the temper-ature limiter (6) has not tripped (press the button firmly).
Filling
It is best to fill the boiler via a fixed/permanent filling line tothe expansion vessel or a hose in the drain valve.
! WARNING!If filling is via the radiator circuit, the shunt valve mustbe in position 10. Otherwise there is a risk of bursting
one of the radiators.
Venting the heating systemBleed the air from the electric boiler through the safetyvalve and the rest of the heating system through itsventing valves.
Keep topping up and venting until all air has been re-moved and the correct pressure has been obtained.
Start-up and inspection1. Check that there is sufficient water and the system has
been vented.
2. Switch on the safety switch.
3. Check that all incoming phases are powered.
4. Check that the MSB (7) is on.
5. Check that the temperature limiter (6) has not beentripped during transport.
6. Switch on the control switch (8).
7. Check that the values for the boiler temperature, flowtemperature and outdoor temperature are appropriate(channels 1-3).
8. Adjust the slope of the curve and heating curve offsetaccording to the needs of the building (channels 6-7).Continue with the following points if EVP 270 isdocked to a heat pump.
9. Check that the red lamp glows in the Channel selectbutton, as this indicates that the docking thermostat isactive.
10. Follow the commissioning and maintenance instructionsfor the heat pump.
11. Check that that lower immersion heat is not blocked.
12. Balance the charge flow between the heat pump andelectric boiler.
13. Set max return temperature on the heat pump to 50 °C.
14. if EVP 270 is docked to a 10 kW heat pump the stoptemperature must be adjusted down to max 50 °C inchannel 21.
Adjustment, charge flow F20XX
For F20XX-8 kW, the charge flow must be a minimum of0.22 l/s and max 0.3 l/s
For F20XX-10 kW, the charge flow must be a minimum of0.27 l/s and max 0.37 l/s
The charge flow can be balanced using the heat pump’s flowand return pipe temperatures.
The difference between Channel T2 (flow temperature)) andchannel T3 (return temperature) is adjusted using the circu-lation pump and control valve. Adjustment is made whenthe flow temperature is approx. 45 °C and at stable opera-tion, 5 minutes after start-up or 5 minutes after defrost.
The temperature difference shall be as in the diagram below.At outdoor temperatures above 28ºC the flow can be in-
creased by 30 % to obtain a lower ΔT.

Secondary adjustment
Air is initially released from the hot water and venting maybe necessary. If gurgling sounds can be heard from theelectric boiler, the entire system will require venting. Whenthe system is stable (correct pressure and all air eliminated)the automatic heating control system can be set as required.See the section "Heating control system" on page 6 and"Front panel" on page 4.
Draining the heating system
The boiler/radiator water can be drained off through thedrain valve (51) using an R15 (1/2") hose coupling. Remove
the cap (80) from the valve. Now screw on the hose couplingand open the drain valve.
The heating system’s safety valve is set to open to allow airinto the system.
NOTEBefore the boiler/radiator water is drained out, the
voltage feed must be stopped.

Setting according to graph
EVP 270 is equipped with an outside controlled heatingcontrol system. This means the flow temperature is regulatedin relation to the current outdoor temperature.
The relationships between outdoor temperature and the flowtemperature is set using the “Select heating curve” and“Heating curve offset” knobs.
The diagram is based on the dimensioned outdoor temperat-ure in the area and the dimensioned supply temperature ofthe heating system. When these two values ”meet”, theheating control's curve coefficient can be read.
“Heating curve offset” is then set. A suitable value for under-floor heating is -1 and for radiator systems -2.

NormalHigh Savings
Since the water is heated in the finned loop at the same timeas it is used, the volume of hot water is dependent on theflow through the coil. This means that a greater volume ofhot water can be drawn off at a low flow rate. If a high flowrate of hot water is required, the boiler temperature can beincreased on channel 9. The available volume of hot watercan be read from the graph.
