INTRODUCTION
A frost thermostat is used to protect your
property from damage by freezing. It works by
turning on your heating system if the
temperature drops below the temperature you
have set on the frost thermostat, allowing the
user peace of mind.
The FT100 from Salus Controls is a stylish
mains voltage thermostat that can switch a
pump, zone valve or boiler to provide localised
protection from freezing, regardless of the
heating controller settings. Fitted with a
protective cover to prevent tampering, this
thermostat has been specifically designed to
be used for 230V AC heating applications.

INSTALLATION
Please read the important safety information at the start of this manual before you
begin to install the device.
The Frost Thermostat should be located in the coldest part of the building, but where
it can respond to a rise in temperature when the boiler switches on. The ideal position
to locate the FT100 frost thermostat is about 1.5m above floor level, in a location
where the thermostat is accessible, reasonably lit and free from extremes of
temperature and draughts. Do not mount the thermostat on an outside wall, above a
radiator or in a location where it may be subjected to direct sunlight.
The electrical connections to the FT100 are made to the supplied industry standard
backplate. This simplifies installation, as no connections are made to the controller
itself. Connection details are shown below - no Earth connection is required for the
correct and safe operation of the FT100, but a parking terminal is provided to connect
an Earth wire if one is present.

After installing the backplate in a suitable location, wiring connections can be made
as shown above. The following criteria apply to the installation:
• The incoming AC mains supply should be 230V AC and fused at 5 amps.
• Optimum cable size for installation is 1.5 mm2; wiring colours should be in
accordance with the current requirements of the IEE Wiring Regulations.
• Cable entry should be from the rear of the backplate.
• All wiring connections should be securely made, and be firmly gripped
beneath the square brass washer on each terminal.

Do not restore the mains supply to the system until all associated items are fully installed.
NOTE: All electrical installation work should be carried out by a suitably qualified Electrician
or other competent person. If you are not sure how to install this thermostat consult either
with a qualified electrician, heating engineer or your boiler / heating system supplier for
advice on how to continue.
Do not remove or refit the FT100 onto the backplate
without the mains supply to the system being isolated.
OPERATION
The FT100 is adjusted very easily by turning the rotary dial on the front of the
thermostat to the required frost protection temperature.
To adjust the set temperature, unclip the protective cover and turn the rotary dial to
the left to set a lower temperature, or to the right to set a higher temperature. Refit
the protective cover after you have finished adjusting the set temperature.
The Light Emitting Diode (LED) on the front panel will light when the temperature is
below the set value, showing that the thermostat is calling for heat from the boiler.
Once the room reaches the set temperature, the LED will turn off and the FT100 will
stop calling for heat from the boiler.
MAINTENANCE
The FT100 frost thermostat requires no special maintenance. Periodically, the outer
casing can be wiped clean using a dry cloth (please DO NOT use solvents, polishes,
detergents or abrasive cleaners, as these can damage the thermostat).
There are no user serviceable parts within the unit; any servicing or repairs should
only be carried out by Salus Controls or their appointed agents.
Should the FT100 frost thermostat fail to function correctly, check:
• The FT100 temperature has been set correctly.
• Heating system time switch or programmer is switched on.
