INSTALLATION
Notes.
1.
Some earth wires are omitted for clarity. Ensure
proper earth continuity when wiring.
2. Numbering of terminals on thermostats is
specific to the manufacturer.
3. This is fully controlled system - set the boiler
thermostat to maximum.
4. Switchmaster valve has grey & orange
auxiliary switch leads but the GREY wire must
be connected to the incoming live supply.
42 TWO SPRING CLOSED VALVE
43 FROST PROTECTION
Pumped only
Central heating systems fitted wholly inside the house do not
normally require frost protection as the house acts as a 'storage
heater' and can normally be left at least 24 hrs. without frost
damage. However, 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
programme 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.
Wiring should be as shown, with minimal disturbance to other
wiring of the programmer.
Designation of the terminals will vary but the programmer and
thermostat manufacturer's leaflets will give full details.
If a boiler is installed in a garage it may be necessary to fit a pipe
thermostat.
Diagram A shows a double pole frost 'thermostat, which should
suffice for all systems which do not use the OFF terminals of the
programmer.
Diagram B shows a 'change-over' frost 'stat, which will cover
most systems which do use CH OFF. If, however, on such a
system the HW pipework is in an isolated part of the house, a
second frost 'stat may be used to protect it. If in doubt, ask your
installer for advice.
