NSPP supports two types of heating control, and we will explain the difference between them. The basic heating control is called a thermostat. Its purpose is to activate the actuator when the temperature drops below a defined tolerance.

For example, if the temperature is set to 20°C and the tolerance is set to 0.3°C, the temperature must fall below 19.7°C for the actuator to switch on. When the temperature rises above 20.3°C, the actuator switches off.

An actuator can refer to a radiator servo valve, electric underfloor heating, an electric heater, a circulation pump (which sends heated medium into the floor heating or radiator), an electric boiler, a gas boiler, or a heat pump. This type of control can be used for multiple zones and is most commonly applied in central heating systems.

The heated medium is usually water or a water-glycol mixture. The water may be chemically treated or untreated (raw water). This is where the capabilities of this basic regulation end.

The second method is called central heating control, which is essentially an extension of the basic regulation system, with the difference that several tasks must be completed before heating can begin.

Example: a temperature sensor sends the temperature reading to the central unit, which first opens the servo valve in the underfloor heating manifold for the room that needs heating. It then switches on the circulation pump for the corresponding floor and activates the heating medium source (such as a heat pump, electric boiler, gas boiler, or the circulation pump located after the storage tank).

With the central heating system, it is possible to control multiple actuators in a precisely defined sequence, separately for each floor and zone within the building. A basic thermostat cannot do this.

Ok. This is my heating/cooling system:

There is a ground floor and first floor. Each floor has one zigbee temperature sensor. Each temp sensor control one circulating pump by a zigbee dry switch trough the NSPP built-in thermostat function. So there is a thermostat in NSPP for each floor. In addition there are three fancoils on the first floor and one on the ground floor. Each fancoils are controled by a Sonoff Mini-D wifi switch. Now I have to use the Ewelink app smart scenes to turn them on/off, mimicking the state of the zigbee dry swiches for the circulating pumps.

How can I implement these setup in the central heating function of the NSPP?

Thanks for the help.

We need to wait until the developers comment, especially on whether the central heating system allows controlling Matter and WiFi devices. In the past, there have been complaints that this is not possible. Then we will comment on whether it will work.
