A practical surface mounted mechanical thermostat suitable for temperature control in industrial environments, refrigeration and cooling cellars, greenhouses and electrical panels. The thermostat permits the user to control a heating system to react to temperature which if low enough could result in frost damage either to the system itself, or to the environment in which it is located. The concept is similar to a room thermostat, but it senses lower temperature and ignores and by-passes all other timers and thermostats.The device should be set at a temperature of between 3 & 5 deg℃ and should be placed above areas which is at risk of frost damage. This unit can be used to switch circulating pumps,boilers or most common motorised zone valves.The device is designed to be used internally. If externally applied, ensure that is enclosed within a weather proofed housing.

Once the wall plate has been adequately secured to an appropriate surface, the body of the thermostat is located by engaging the broad head of the studs A, into the holes and slots B, and then pushed down until secure. For additional security,the edges of the tags C, can be distorted to prevent the unit from being lifted up and off the wall plate. The electrical connections can now be made for which the temperature adjustment dial should be gently prised off and the front housing screws removed.

Turn the dial to the desired setting making sure the temperature at which the device is required to operate frost protection, lines up with the mark on the main body of the thermostat.
