Block diagram
The heating system (radiators or floor) is controlled by an
On/Off room thermostat.
The domestic hot water tank is controlled by an intermediate
NTC sensor. The domestic hot water priority is always
active.
In this configuration, the boiler constantly adapts its operation
to the outdoor temperature, if an outside temperature
sensor is connected.
The circulator is triggered as soon as the room thermostat
generates a heat demand.
Advantages for the user:
- Comfort
- Maximum output
- Simplicity of the system
