Auxiliary Pool Water Heating System (AWH Model only*) (6)
The auxiliary pool water heating system is provided by others. Typically a gas fired or electric pool water heater
is used. The CPCS-PCP provides a dry contact closure that signals a need for auxiliary water heating. The
contacts of the CPCS-PCP may be connected directly to the heater’s control circuit provided the circuit is 24 VAC
maximum and the current does not exceed 1 amp inductive. Any other applications will require an additional
relay (by others) to be installed between the CPCS-PCP and the pool water heating system.
Auxiliary Air Heating System (7)
Typically a duct mounted electric heater, hot water coil or a factory installed unit mounted hot water coil is
used to provide air heating. The CPCS-PCP provides a form “C” (NO and NC) dry contact closure that signals
a need for auxiliary air heating. The CPCS-PCP contacts may be directly connected to an electric duct heater
control circuit provided the circuit is 24 VAC maximum and the current through the contacts does not exceed 1
amp inductive. Figure 4-9 shows a typical installation that utilizes a 3-way hot water control valve and a unit or
duct mounted hot water coil.

External Alarm System (8)
The CPCS-PCP provides a normally open contact closure for connection to a building management system. If a
fault occurs, the controller will energize this output to indicate that there is a problem with the dehumidification
system. The remote interface unit will display the cause of the fault and provide a suggested course of action.
This output may also be used to energize an external alarm light or buzzer. It may also be directly connected
to an external circuit as long as the circuit is 24 VAC maximum and the current through the contacts does not
exceed 1 amp inductive.
