USER'S GUIDE

1. Boiler on/off switch

2. Summer/winter switch (is used to turn the heating circulator on and off).

3. Safety warning indicator (lights up when the temperature of the flue gas or water of the

primary system is too high).

4. Thermo-pressure gauge (displays the boiler temperature and the pressure within the

primary system).

5. Manual reset safety thermostat (enables the boiler to be reset after overheating of the

primary water system).

6. Thermostat control (allows the boiler temperature to be set between 60°C for the minimum

position and 90°C for the maximum position).

Important recommendations for the correct operation of the appliance

If the boiler switches frequently to safety, contact your installer.

If your boiler is connected to a Domestic Hot Water (DHW) heating tank, make sure

that the temperature of the heating thermostat is higher than that of the DHW

thermostat in order to guarantee optimal operating conditions.
