HTR
maintaining the temperature at desired setpoint. The

Cool Only
Used in applications like Deep Freezer, Cold Cabinet, Lab

ambient. The
(Compressor) control output switches ‘cooling
CMP
source’ for maintaining the temperature at desired setpoint. The
HTR
(Heater) control output is inactive (kept off).
Heat + Cool
Used in applications like Environment Chamber, BOD Incubator,
etc.; that require either lowering the temperature below or rasing
the temperature above ambient. Both, the
