Temperature sensors connection:

Connect DHW sensor into the connection board (DHW sensor output).

Connect Valve 1 sensor (for CH) inside the connection board into the "Valve1 sens." output.

Connect Valve 2 sensor (for FH) inside the connection board into the "Valve2 sens." output.

Connect Return temperature sensor on the water inlet close to the boiler and connect it inside the connection
boart into the "Return sens." output.

Connect Weather temperature sensor inside the connection board into the "Weather sens." output.

Check correct connection of CH sensor, which is inside the sink on the water outlet on the back side of the
boiler. There should be no risk of loosing the sensor and falling down out of the sink.
Mixing valves connection:

Conenct Valve 1 (for CH) inside the connection board into the "Valve1" output.

Conenct Valve 2 (for FH) inside the connection board into the "Valve2" output.
Room regulator connections on each heating system (CH and FL):

It is necessary to connect one thermostat for each hating circuit (CH and FL). Room thermostat will operate
mixing valves temperature accordingly to the current requests from room thermostat.

Connect room thermostats inside the connection board into selected outputs "Room regulator 1 or 2" or into
"RS" output if you use RT10 room regulator.

Keep in mind that you can use only one RT10 regulator with each Biopel.

We will activate and setup each thermostat later.
Sat basic temperatures:

Select CH temperature in Main settings, "CH temperature".

Select DHW temperature in Main settings, "DHW temperature".
DHW activation:

Activate "Water heater priority" in Main settings, Working modes.

Boiler will heat the domestic hot water tank as a priority according to the preset DHW temperature (DHW
pump is turned on as a first until set DHW temperature is reached).

Caution, DHW pump will be activated only if CH temperature is higher than actual DHW temperature to be
sure that colder CH temperature isn't cooling down DHW tank.

When set DHW temperature is reached, DHW pump is deactivated and CH pump is activated to maintain
circulation of water inside heating system and to protect boiler overheating.

CH or DHW pump will be activated only if measured CH temperature is 40°C or higher. Value set in service
menu, "Pump switch on temperature".

DHW pump will be activated again when DHW temperature drops by number set in Service menu, "DHW
hysteresis". When DHW pump activated, CH pump is deactivated and the opposite.
Activation and setup os mixing valve 1 (for CH):

Activate Valve 1 (for CH) in Fitters menu, Build-in valve 1.

Set valve 1 temperature in Fitters menu, Build-in valve, Valve temperature.

Mixing valve will keep this temperature in the set level. In case of reaching the set temperature, valve will
close automatically to minimal 5% opening, which is the value set from the factory. It can be changed any time
in Build-in valve 1 setup.
Activation and setup os mixing valve 2 (for FH):

Activate Valve 2 (for FH) in Fitters menu, Build-in valve 2.

Change the type of valve in Fitters menu, Build-in valve 2, Valve type, Floor valve. Maximal floor heating
temperature is 55°C to protect the floor heating agains higher temperatures.

Set required valve 2 temperature in Fitters menu, Build-in valve, Valve temperature.

Mixing valve will keep this temperature in the set level. In case of reaching the set temperature, valve will
close automatically to minimal 5% opening, which is the value set from the factory. Ut can be changed any
time in Build-in valve 2 setup.
