 RA Combo Sensor (21) measures temperature and humidity of the pool room air (Return Air) entering the
dehumidifier. It is located at the main filter rack.

OA Temperature Sensor (22) measures outdoor air temperature; it’s located at the OA filter rack.
o
As an option, the combo sensor (instead of regular thermistor) can be installed at the OA intake to
measure both the temperature and humidity of the outdoor air.

ET (EvapT) Temperature Sensor (23) measures the temperature of air leaving evaporator coil. It’s located
directly downstream of the evaporator.

SA temperature sensor (24) measures the temperature of the air leaving the dehumidifier (supplied to the
premise). It must be located downstream of the space heater :
o
In some cases, where the space heater is external to dehumidifier, the sensor will be provided with
the dehumidifier to be field-mounted into the supply air ductwork downstream of the space heater.

If the dehumidifier is equipped with the pool heating option, the Pool Water Temperature sensors ( Pool In
(25) and Pool Out (26)) measure the entering and leaving pool water temperature. The sensors are located
directly at the respective connections of the coaxial pool water heat exchanger.
o
As an option, the pool water heat exchanger piping/manifold may have water flow switch also.

The compressor’s discharge line (high pressure side) is equipped with Temperature and Pressure sensors set -
Discharge Temperature Sensor, High Pressure Transducer and High Pressure Switch (27) - to protect the
compressor and control its operation. A similar function is performed by Suction Temperature, Low Pressure
Transducer and Switch (28) located at compressor’s suction line (low pressure side).

Main Electric Panel, apart from devices listed above (control board, OP, etc.) also contains Voltage Monitor;
some optional control sensors and devices such as an air pressure differential sensor, current sensor(s). It may
also be located in main electrical panel or in the dehumidifier in general.
