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 dead-band 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 heatpump, the reversing valve can be energisation on either a heat or cool
demand.
