Frost Thermostats
3.5.1 Combi Boilers
The switched live from the frost thermostat (the frost thermostat must be supplied by a
permanent live) should be connected to number 5 on the boiler terminal block. In order
to protect the fabric of the building as well as the boiler and pipework, the thermostat
should be located in the coldest part of the house but where it can respond to any
temperature rise.
3.5.2 Kabin Pak Combi Boilers
As the boiler is supplied with a factory fitted frost thermostat all that is required is for a
permanent live to be supplied to the control panel.
