Signalling demand
.
Briefly turning a hot water tap on and then off signals demand
so that the water is then heated up to the set temperature.
5.5 FROST PROTECTION
Frost Protection is active as long as there is power to the boiler.
If the temperature within the boiler falls below 8°C the pump will
run to circulate water and prevent the system freezing.
If the temperature within the boiler falls below 5°C the boiler will
fire periodically, bringing the boiler temperature up to 12°C to
avoid the possibility of the system freezing.
This process will be repeated until such time that the boiler
temperature does not drop below 5°C.
Signalling demand enables maximum gas and water
economy.
