Min. Flow
The minimum flow temperature is the lower limit of the heating curve, and as such, the reference flow temperature of the heating
circuit. In addition to that, the minimal flow temperature is the reference flow temperature for the frost protection function.
Max. Flow
This value is the upper limit of the reference flow temperature of the heating circuit. If however, the temperature of the heating cir-
cuit exceeds the set value, the heating circuit shuts down until the temperature falls below this value. After 55 seconds, rinse for 5
seconds.
The customer must provide an additional limiting thermostat which is connected to the pumps in series (e.g. underfloor
heating) for safety.
Turn off HC
Summer: HC turns off when the summer/winter changeover (outside temperature) is exceeded.
Summer + Room: HC is turned off when the summer/winter changeover (outside temperature) or the room setpoint temperatures
are exceeded.
Insulation factor
The insulation factor is determined over time from the outdoor temperate. Depending on the selected factor, the outdoor tem-
perature after the set delay has an influence on the calculation of the flow temperature.
0 = Off, 1 = 15 minutes, 2 = 60 minutes, 3 = 120 minutes, 4 = 300 minutes
For better insulated buildings, a higher insulation factor can increase comfort and save energy.

Mixer

This menu contains all settings relating to the mixer of the heating circuit.
Direction
The direction of the mixing valve can be set here.
Mixer run time
Mixer-specific setting of the running time required by the mixer for a full speed.
Mixer increase
If the temperature rises very fast, this value will be added to the measured flow temperature so that the mixer's reaction is
stronger. If the measured temperature does not rise any further, the measurement is used again. The measurement occurs once
every minute.
Mixer off factor
The calculated pause time of the mixer is multiplied with the value set here. If the pause factor is '1', the normal pause time is
used, '0.5' will halve the normal pause time. Setting the pause factor to '4' would quadruple the pause time.
Mixer turn time
The mixer is switched on i.e. it is opening or closing for the time span set here, then the temperature is measured to control the
flow temperature.

Heating Pump

Inlet Flow Sensor
In this menu, the sensor to measure the flow temperature is set.
Return flow sensor
In this menu, the sensor to measure the return flow temperature is set.
Delta Pset
Adjustment of the sudden pressure difference in the system, which sets the controller to DELTA-P mode and runs the pump at the
maximum speed set for a defined time. Set the pressure difference between flow and return sensors.
