Hi,
In my central heating system the oil burner seems to be over riding the clock/timer. The following is seen:
When the clock/timer is on (all 3 channels) and the thermostats in the house reach the required temperature, the motorised valves close as expected. However the oil burner does not stop and continues to burn.
Another scenario:
When the clock/timer is in standby the oil burner still burns and continues to do so until thermostat at boiler kicks in. Then it starts again when temperature falls.
In the above instances power should not be getting to the burner but it is.
Could it be any of the following and how much would it cost to fit and replace
Sunvic motorised valve is not shutting down properly, the orange wire is still getting power from the gry wire, replace the valve. or prob just the head of the valve faulty, so easy fix if brass part good.
