Heating Availability
Room-temperature control is an important part of humidity control.
The dehumidifier capacity is matched to the rated pool-evaporation rate. The pool-evaporation rate will increase if
1. the pool temperature remains the same while room temperature is decreased, or
2. the pool temperature is increased while the room temperature remains the same.
Space heat must
be under the control of the DRY-O-TRON®. All installations must have space heat available
year-round. The DRY-O-TRON® will command only enough heat to keep the evaporation rate within a workable
range.
NOTE: Where space heaters are by others, the space heaters must heat the supply air. Do not
install a heater in
the return duct.
NOTE: Attempting to heat the air with the pool will increase the evaporation rate.
NOTE: For units with hot-water or hot-glycol space heaters by Dectron, unless otherwise noted, full heating
capacity requires the water or fluid temperature to be between 160°F (71°C) and 180°F (82°C).
NOTE: Unless equipped with a space heater, the DRY-O-TRON® does not produce significant heat - it
recycles heat. A dedicated space heater must
be ordered with the unit or provided by others.
NOTE: Building heat losses are calculated by others and consequently are sized by others. Dectron does not
select space-heater capacities.
COOLING AVAILABILITY
Where the DRY-O-TRON® unit has the cooling option and any required cooling water or other fluid is
provided by others, it is essential that the cooling water or fluid be available at any time the DRY-O-TRON®
may be operating.
Do not turn off cooling water or fluid based on time-of-day, time-of-year, outdoor temperature, or other
considerations.
