Hi,
Boiler is around 7 yrs old now.
Noticed recently the heating side is taking a lot longer to reach the desired room temperature, set on the Honeywell programmable thermostat controller.
Discovered the heating mode mode control knob on the boiler does not seem to function . The manual states that during adjustment between minimum and maximum , the LCD should flash, this should continue for a while followed by the central heating flow temperature, or the time if the room thermostat is off.
Unfortunately the display only shows the time ?
Could this be the cause of the low heat from the radiators ?
The boiler has been serviced at annual intervals by corgi registered engineer.
Thank you..
Trev
