CellarPro AIR HANDLER 6500 HORIZONTAL, 7090 - Manual (Page 25)

25
Humidifier (optional):
Recommended for installations where the ambient humidity is insufficient to maintain 50
to 70%RH inside the cellar. The humidity control is remote mounted with 10ft of
interconnecting wire inside the cellar. Refer to separate manual for detailed installation
and operating instructions for the humidifier and humidity controller.
Heating (optional):
The air handler can be configured with an electric air heater for installations where the
cellar may drop below the desired set point. The controller is factory programmed to
automatically activate the heater and the evaporator fan when the cellar temperature is
below the desired set point (parameter SET) minus the temperature differential
(parameter HY). For example, if the set point (Set) is 55 , and the differential (HY) is 4,
the heater will energize when the cellar temperature reaches 55 minus 4 = 51°F, and
turn off when the cellar reaches 55°F. Refrigeration will be activated when the cellar
temperature reaches 55 plus 4 = 59°F. If a tighter range is required, the HY should be
set to "2" for the heating season. If an optional bottle probe is used to maintain the
cellar temperature, the factory setting for HY is "1", and adjustment is not required.
There are two heating element options: 900W and 1800W. An application chart is
shown below to assist in selecting the correct wattage. For the majority of applications,
the 900W heater is recommended.
