The following tips can help in the event problems occur
General
Before you call in your heating engineer, you should
check the following:
• Is your plant switched on? Check main switch and all
other switches
• Are all fuses of your plant in order?
• Is enough fuel in the tank?
• Have settings been changed by unauthorized per-
sons? (Time of day, setpoints, etc.)
• Does a fault appear on the display?
The heating always maintains the same room tem-
perature:
• Check the room operating mode (only
lowers
and raises the room temperature)
• Has the actuator been disconnected from the valve?
Connect it!
The required room temperature is reached either too
early or too late:
• Change the time program
• When the building is well insulated, it takes more time
to cool down
The heat source does not operate any more:
• The burner has initiated lockout. Press the reset
button!
• The heating circuit pump and / or the boiler pump
does / do not operate. Check the fuses!
• The fuel tank is empty or the fuel pump does not
operate
The heat source operates, but there is no supply of
heat:
• Operate the heating valve manually
