Section IV: Installation
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 ECC-PCP provides a dry contact closure that signals a need for auxiliary water heating. The contacts of the ECC-
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 ECC-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 ECC-PCP provides a form “C” (NO and NC) dry contact closure that signals a need for
auxiliary air heating. The ECC-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. The figure below
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 ECC-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.
