Delay
Switch delay of the heat and cooling request. In order to prevent the heat or cooling request to be activated if there are heat devi-
ations, the corresponding relay is switched up ot 5 minutes before the switch conditions occur.
Tset
The target temperature at the set sensor for the function dissipation (cooling simple).
Season switch
The seasonal switch changes the operating mode of the heat pump (compressor) between "heating" and "cooling".
For this purpose, the heat pump (compressor) must be suitable for reversible operation.
Please refer to the technical documentation of the heat pump used.
If request for DHW is activated for the heat pump in the controller, the operating mode of the heat pump automatically switches to
"heating" mode in case of a DHW request.
Min. flow cooling
This value is the lower limit of the reference flow temperature of the cooling.
Dew point correction
The internal dew point curve is moved parallel with this value. The dew point calculation is used to calculate at which room tem-
perature there is an undesired condensation (precipitation) at the currently measured humidity. This calculated room temperature
will not be undershot with the cooling system and therefore represents a temperature lower limit for the cooling system.
The calculated room temperature can be moved by up to 10 °C with the dew point correction.
Example 1: You determine that there is precipitation with the default value,
so you increase this correction value.
Example 2: Condensation/precipitation can be ignored, instead a
stronger cooling system is required. You therefore decrease this correction value.
In case of reduction of the calculated temperature with the help of dew point correction condensation / perspiration / pre-
cipitation can occur, which, among other things, may cause the formation of mold.
Max. flow cooling
This value is the upper limit of the reference flow temperature of the cooling.
Cool storage
The storage can be cooled through this function.
Yes: The flow and buffer storage are cooled down to the reference flow temperature + hysteresis.
No: It is cooled down to the reference flow temperature + hysteresis, the temperature in the buffer storage is ignored.
Buffer sensor
If the buffer tank is to be cooled in the cooling mode, the corresponding sensor can be set here.
Solid fuel boiler
In solid-fuel boiler function, a pump is controlled with a assigned relay, which loads the heat energy from a solid-fuel boiler into a
storage tank.
The solid-fuel boiler function controls the charge pump of a solid-fuel boiler based on the temperature difference between the
solid-fuel boiler sensor and the storage tank sensor.
If a control output (V1 or V2, ...) is used with this function, a speed control with a PWM / 0-10V HE pump is possible.
Solid fuel boiler Tmax
Maximum temperature in storage tank. If this is exceeded, the relay is switched off.
Solid fuel boiler Tmin
Minimum temperature in the solid fuel boiler to start the pump.
If the temperature at the solid fuel boiler sensor exceeds the temperature set here, the relay switches on the pump, if the other
starting conditions are met.
Below the solids boiler Tmin temperature, the solids boiler function is deactivated.
ΔT Solid fuel boiler
Switch-on and switch-off difference between solid fuel boiler (SFB) and storage tank.
