INSTALLATION

39 EXTERNAL ELECTRICAL CONTROLS

Wiring external to the boiler MUST be in accordance with the current I.E.E. (BS.7671) Wiring Regulations and any local regulations.

For IE reference should be made to the current

ETCI rules for electrical installations.

The fuse should be 3A.

Room Thermostat

If the thermostat has a neutral connection use it. (It provides for more energy efficient operation by reducing switching temperature differentials.)

Frost Protection

If parts of the pipework run outside the house or if the boiler will be left off for more than a day or so then a frost thermostat should be wired into the system. This is usually done at the programmer, in which case the programmer selector switches are set to OFF and all other controls MUST be left in the running position.

The frost thermostat should be sited in a cold place but where it can sense heat from the system.

If the boiler is installed in a garage it may be necessary to fit a pipe thermostat, preferably on the return pipework.

Important. Ensure that the frost thermostat is wired so that the system pump and/or external diverter valve is energised, as appropriate.

Designation of the terminals will vary but the programmer and thermostat manufacturers' leaflets will give full details.

Diagram A shows an application to boilers fitted with a room thermostat only.

Diagrams B and C show applications to boilers fitted with alternative time controls.

Earths are not shown for clarity but MUST NEVER BE OMITTED.
