F. AUX. HEAT
When in the
HEAT PUMP
mode, if the outside ambient temperature
is measured to be below 30°F and the vehicle is equipped with a
furnace connected to the Comfort Control Center, the control will
automatically select the
FURNACE
operation and the
HEAT PUMP
will shut down.
Important:
If vehicle is not equipped with a furnace no heat
will be available below 30°F. IF vehicle is equipped with a
furnace and it is connected to its own thermostat, it must be
manually turned ON and OFF for operation.
When this happens, the
AUX. HEAT
and the
HEAT
PUMP
indicators
on the LCD will illuminate. Once the outside ambient temperature is
measured above 38°F, the control will return to the
HEAT PUMP
operation and shut down the furnace if it is connected to the Comfort
Control Center. If furnace is not connected to the Comfort Control
Center, the furnace thermostat must be manually turned off.
G. DEFROST CYCLE
This cycle is active during
HEAT PUMP
operation and allows the
heat pump to operate down to 30°F. When the outside ambient
temperature is less than 42°F and greater than 30°F, a defrost timing
cycle will begin. The defrost timing cycle will allow operation of the
heat pump for 25 minutes. The fan will then be shut off, the refrigerant
flow reversed and run for 4-1/2 minutes, this is the
DEFROST
cycle.
The refrigerant flow will then be returned to normal and, after a 30
second delay will continue until the temperature is greater than 42°F
or until the temperature becomes less than 30°F, at which time the
furnace will activate. (See
AUX. HEAT
). During the defrost cycle, the
DEFROST
indicator on the LCD shall be illuminated.
H. OPTIONAL AUTOMATIC GENERATOR START (AGS)
On vehicles equipped with an optional AGS kit the vehicle generator
will automatically start when any zone calls for cooling and will shut
off when all zones reach set point.
1. Put the power switch in the ON position.
2. Momentarily depress and release the ZONE push-
button until AGS indicator appears on the LCD.
3. Momentarily depress and release the MODE push-
button to select AGS status.
Important:
When shore power is available, AGS must
be switched to the off position.
