CONTROLS, GENERAL

1.18The controls fitted to the system will provide two functions:

To control the comfort level in the house.

To maintain safety in the event of misuse or mechanical failure.

COMFORT CONTROLS

1.19A programmable timer switches the pump on when heat is required and off when it is not.

The timer, when combined with a room thermostat and

/or thermostatic radiator valves, enhances the comfort levels in the house.

Some room thermostats combine the function with the timer and can be programmed to reduce the room temperature rather than turning the system off. This is effective in not allowing rooms to become too cold and speeding up recovery time.

1.20The hot water cylinder can also be fitted with a thermostatic valve which turns off the flow when the cylinder has reached the desired temperature, but the heat leak radiator will have to be bigger to cope with the extra load when the tank is isolated.

SAFETY CONTROLS

1.21A high limit thermostat is fitted to the gravity flow pipe set at 80˚C. This thermostat should be connected to the pump so that the pump is turned on if the temperature exceeds 80˚C. This will prevent accidental boiling in the gravity circuit.

1.22It is also recommended to fit a low limit thermostat on the central heating return set at 45˚C. This thermostat will turn the pump off if the return temperature falls below 45C. This will prevent corrosion and condensation within the stove.

NOTE – Further information on solid fuel central heating systems can be found in the HETAS engineers training manual.
