that will operate when the selector switch is in the ( ) position. If the boiler temperature falls below 5° C, then the

boiler will operate until the water temperature has been raised.

2.If a system frost thermostat has been fitted (your installer will be able to advise you), then to operate correctly and protect your system, the gas and electricity must be left on and the appliance set in the central heating mode.

3.The boiler incorporates an integral pump protection feature which continually monitors the time since the pump last operated. To prevent seizure, the pump will operate for approximately 1 minute if it has not run in the last 24 hours.
