Product overview
The thermostat is primarily designed for use in systems equipped with 4-pipe fan-coil units. It may also be used in other heat / cool systems, including split systems and air to air heat-pumps.
The thermostat controls room temperature by sequencing the operation of heating and cooling. A selectable deadband prevents overlap of heating and cooling processes. For systems equipped with compressor derived cooling, including heat-pumps, a selectable compressor delay timer is also included. If used to control a heat-pump, the reversing valve can be energisation on either a heat or cool demand.
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.
•Fix at a height of approximately 1.5m from the floor, away from draughts or heat sources such a fan-coil outlets, sunlight or o ce equipment.
