If pool water heating is required (AWH models only), the hot gas flows into a pool water condenser, where it adds energy
to the incoming pool water. This heats the pool water while the refrigerant is condensed into a warm liquid. If space
cooling is called for, the refrigerant flows to the auxiliary air conditioning condenser bypassing the air reheat coil and
pool water condenser and allowing cool air from the evaporator coil to provide space
ECC-PCP CONTROL SYSTEM
OVERVIEW
The ECC-PCP controller is a micro-processor based system that maintains pool enclosure humidity and air and water
temperatures at optimum levels automatically. It is also possible to monitor this critical data via the Internet using the
optional Remote Access Package (RAP). This also allows the controller to be accessed from the factory via the internet
or a telephone line. (AWH and HCDH only)
The ECC-PCP is designed to work with the PoolComPak™ dehumidification system to provide an environment that is
both comfortable and cost effective. It controls unwanted humidity in the pool enclosure and helps to prevent unsightly
condensation from forming on surfaces.
The ECC-PCP provides accurate control and allows the user to monitor system parameters and change setpoints easily.
For this purpose, a remote interface unit with a text display and keypad is provided. The remote panel should be mounted
outside the pool space, in an office or in the equipment room. (The ECC-PCP remote interface unit contains no sensors.)
All setpoints are saved in the memory of the ECC-PCP and are not erased in the event of a power failure. Critical
operating data can be easily accessed by a service technician for the purpose of system operation and evaluation.
HUMIDITY CONTROL
As the dewpoint temperature within the pool enclosure rises above the desired setpoint, the ECC-PCP activates the
compressor within the PoolComPak™ to begin the dehumidification process. If the space temperature is below the
desired setpoint, the heat recovered during dehumidification is directed to the air reheat coil for space heating. If the
pool water temperature is also below the setpoint, some of the recovered heat is directed to the pool water condenser
(model AW only) for pool water heating. If neither air heating nor pool water heating is required, the recovered heat
can be directed to an auxiliary air conditioning condenser if the system is so equipped. If the system does not include an
auxiliary air conditioning condenser, the ECC-PCP will direct the recovered heat to the air reheat coil until the need for
dehumidification is satisfied.
COLD SURFACE TEMPERATURE HUMIDITY RESET
The ECC-PCP control system includes a sensor that measures the temperature of the coldest surface in the pool
enclosure, usually an exterior window or door frame. When the temperature of this surface approaches the dewpoint
temperature of the space, the controller lowers the humidity setpoint to activate dehumidification. This function helps to
prevent condensation on the cold surface.
SPACE HEATING
When the compressor is running, the ECC-PCP directs the recovered heat to the air reheat coil. Space heating will
continue until the space temperature reaches the setpoint. The ECC-PCP will activate the auxiliary space heating system
if the PoolComPak™ unit is unable to satisfy the heating need with heat recovered during dehumidification.
The ECC-
PCP will activate the auxiliary pool water heating system if the water temperature cannot be satisfied with recovered
heat. An auxiliary pool water heater must be supplied as part of the pool water pump and filter system.
