2. Numbering of terminals on thermostats is specific to the
manufacturer.
3. This is a fully controlled system - set the boiler thermostat to
maximum.

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 'stat 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 'stat 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. Diagram A shows a double
pole frost 'stat, 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.
