Settings for multi-zone heating/cooling
To view HVAC programming examples, please see Niko Home Control programming examples.
Multi-zone heating/cooling with zone valves can only be performed if the following conditions are met.
In case of a heat pump with WC01 control:
The heat pump has a buffer tank connected in parallel, as well as an additional bypass circuit.
The Niko Home Control thermostats must be forced/blocked in the relevant mode via the Niko Home Control digital input module connected to the heating/cooling output of the heat pump.
Input closed = cooling
Input open = heating
In case of a heat pump with One Base control:
The heat pump only takes into account the weather-dependent control, clock program (or manual) and flow temperature T0.
The heat pump decides between heating or cooling, depending on the weather. The Niko Home Control thermostats must be forced/blocked in the relevant mode via the Niko Home Control digital input module connected to the heating/cooling output of the heat pump.
Input closed = cooling
Input open = heating
