Product overview

The thermostat is designed for use in systems equipped with fan
coils served by a 2-pipe central changeover system. The thermostat
controls the operation of a motorized valve which, during heating
periods, opens when heat is required and which, during cooling
periods, opens when cooling is required.

The changeover from heating to cooling is achieved automatically
by measuring the temperature of the fl ow pipe. If the fl ow
temperature exceeds 30°C the thermostat operates as a heating
thermostat, if the fl ow temperature is less than 16°C the thermostat

operates as a cooling thermostat

Installation

Important note: It is essential that the circuit in which the pipe
sensor is located is not closed off and that water circulates past
the sensor at all times. This may require the fi tting of a bypass

valve between system fl ow and return at the end of each circuit.

• First, remove the wallplate from the back of the unit.

• Ensure that there is a minimum of 50mm above the unit
and 100mm below the unit in order to mount the plug-in
module.
