SCHEMATIC DIAGRAM
The heating system is controlled by an On/Off room thermostat.
In this configuration, the boiler constantly adapts its operation (minimum
temperature =60C) 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

Before the boiler’s start up, an “Auto Set” is necessary so that the boiler
detects the DHW sensor.
To do this, turn the right button to “RESET” then start up the boiler by
pressing on the ON/OFF switch.
From the time that the display shows “SET” the “RESET” button can be
released.
