Reverse the above process.
7.1.2 Compartment Fans
There are two compartment fans located with-in the dual zone wine cellar. Both the upper and lower
compartment has a dedicated fan for independent air circulation of each zone.
The compartment fans are located in the supply air compartment and mounted to the evaporator cover
(See figure 12.19). The fans draw air from the return air compartment, across the evaporator coil and
into each compartment area.
Each compartment has its own dedicated return air damper. This damper is automatically drawn open
when that compartment fan is running. The damper door consists of a Mylar material that is taped into
position and simply opens when air is drawn through it when the compartment fan is running.
The following sequence is how the compartment fans relate to the basic system operation.

7.1.2.1 Compartment Fan Operation
Typical compartment call for cooling cycle:
At cut-in temperature:
On:
Compressor, Condenser Fan, & Compartment Fan
Off:
Heater / Fan
At cut-out temperature:
Off:
Compressor, Condenser Fan, Compartment Fan, Heater / Fan
The compressor and condenser fan cycle on and off together. The compressor has a minimum off time of
five (5) minutes.
A call for cooling in either compartment will activate the compartment fan. The other compartment fan
will not run if there is no call for cooling.
A call for cooling in either compartment will energize the fan for that compartment.
A call for heat in either compartment will de-energize the fan for that compartment.
If the set-point for either compartment has been obtained the fan for that compartment will be de-ener-
gized.
If a compartment has a call for cooling while the other compartment is satisfied.
The compressor and condenser fan will energize.
The compartment fan for the call for cooling compartment will energize.
The compartment fan for the satisfied compartment will remain off.
This will prevent evaporator air from being circulated into the satisfied compartment. However, the
heater / fan for the satisfied compartment may energize to heat any cool air which will migrate or con-
vect into that compartment.
