Product Overview; Installation - Danfoss RET 230 HC-1 Installation Instructions Manual

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