Boiler operation by the user
The boiler works automatically according to the regulation elements setting and the user only does
following operations that the worker commissioning the boiler is obliged to acquaint him with:
1. Boiler switch on and switch off by means of the network switch on the boiler control panel.
2. Setting and control of required heating water temperature in the range of 0 – 80 °C. We recommend
to set this temperature only at the boilers without regulation. If the boiler is controlled by the indoor
thermostat or another regulation the boiler thermostat must be in the highest temperature position.
3. If the boiler failure state occurs, the signal lamp signalling the burner fault lights up in the boiler control
panel. In case of electricity network outage the burner is switched off and after the network voltage
restoration the burner is restarted automatically.
4. Safety thermostat unblocking. If the boiler has been switched off by a safety thermostat the signal lamp
signalling “the temperature exceeded” lights up in the control panel. Thermostat can be unblocked by the
user by means of "unblocking" button at the safety thermostat positioned at the rear panel of the control
box.
