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 flow pipe. If the flow temperature exceeds 30°C the thermostat operates as a heating thermostat, if the flow temperature is less than 16°C the thermostat operates as a cooling thermostat
!Important note: It is essential that the circuit in which the pipe sensor is located is not closed o and that water circulates past the sensor at all times. This may require the fitting of a bypass
valve between system flow and return at the end of each circuit.
Installation
•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.
