Air Conditioning with Water-Cooled Condenser
The PoolPak™ unit can be equipped with a factory-mounted or remote-mounted air conditioning water condenser. This
condenser can be either cleanable or non-cleanable. Sensible and latent heat recovered in the air conditioning mode is
rejected to the water condenser if pool water temperature requirements are satisfied.
Air Conditioning with Chilled Water Coil
When chilled water is available, a chilled water coil can be factory-installed upstream of the supply fan. The coil has a
factory-installed and wired two-way flow control valve and is controlled by the PoolPak™ control system.
POOL WATER HEATING
If the space temperature is at or above the set point and the pool water temperature is below the set point, hot gas
is directed to the pool water condenser when the compressor is running. During times when the pool water requires
more heat than is available from the pool water condenser, the PoolPak™ activates the auxiliary pool water heater. An
auxiliary pool water heater must be supplied as part of the pool water pump and filter system.
NOTE
Contact factory for pool water temperature set points greater than 87° F
SMART PUMP CONTROL
Smart Pump control allows the ECC to control operation of the PoolPak™ water loop pump. When the ECC determines
that pool heating and space cooling are required, a contact closure signal activates the remote pump. The pump will be
deactivated when the pool heating or space cooling requirement is satisfied.
OCCUPIED/UNOCCUPIED CONTROL MODE
The PoolPak™ unit time clock allows 7-day, 24-hour scheduling of operational control for both occupied and
unoccupied times during the year. During unoccupied times, the outside air and exhaust dampers are kept in the closed
position to minimize the air-heating load. During occupied times, the PoolPak™ operates to maintain programmed
natatorium parameters.
PURGE MODE (SR AND SEP)
The PoolPak™ has a purge cycle to fully ventilate the natatorium at the airflow (CFM) specified for the unit’s supply
fan. The purge cycle is programmable by the owner as necessary to ventilate the natatorium after shocking the pool. Unit
controls provide completely automatic operation by controlling the supply fan and return (or purge) fan and by opening
the outside air and exhaust air dampers for the programmed time intervals.
CO2 BASED DEMAND VENTILATION
The amount of outside air ventilation provided is controlled by the PoolPak™ unit based on the CO
2
level sensors in the
return air stream.
EVENT MODE (SR)
The Event Mode changes the ventilation air quantity to meet the demands of an event or situation where additional
outside air is needed. The unit controller can store up to 28 schedule events, which is user adjustable at the Remote
User Interface (RUI). During Event Mode, the minimum damper position is raised to a value higher than the minimum
damper setpoint. For each event, the screen shows the day of the week, the hour in 24-hour format, the minute, and the
event type.
