Outdoor Air Condenser and Fluid Cooler Operation.
Based on the type of the outdoor condenser or fluid cooler fans’ type (two-speed fans or EC-type/modulating
fans), respective signal(s) are sent by control system to engage said fan(s): for two-speed fans - on/off signals
(switching speeds, based on compressor head pressure level), for EC-type fans - variable 0-10VDC signal
(proportional to the compressor head pressure level). Refer to the fans’ type and wiring diagram if/when needed.
If the fluid cooler is equipped with the built-in pump package (to establish cooling fluid flow between dehumidifier
and the fluid cooler or to serve as additional/booster pump), the said pump is also engaged along with fluid cooler
fans – pump would stay engaged while fans are engaged (regardless of the fans’ speed).
Space Heating
When premise air temperature drops below the set point, the dehumidifier control system issues a call for Space
Heating Mode and engages space heater (electric heater, hot water coil with valve, gas boiler etc.) by sending space
heating signal, respective to space heater control type - on/off, variable (0-10VDC), etc.
