I installed a Honeywell DT90E digital room thermostat and all is working and controlling the room temperature but when the thermostat calls for heating the boiler only cuts in for about a minute and then the stat cuts out the boiler.
The stat is positioned in the hall away from the rad and there is no TVR fitted to this radiator.
Is there a setting in the programme that will allow the boiler to remain 'on' longer until the room temperature reaches the set point?
