6. THERMOSTAT SPECIFICATIONS
THERMOSTAT - 6795B3451
SUB-BASE - 7330-3401
SET TEMP. RANGE: 55 TO 90 DEGREES F.
DISPLAY TEMPERATURE: -20 TO 160 DEGREES F.
SCALE: DEGREES FAHRENHEIT
DISPLAY FORMAT: LIQUID CRYSTAL DISPLAY
RESOLUTION: ONE DEGREE F.
ACCURACY: ± 2% OF DISPLAY TEMPERATURE RANGE
SAMPLING RATE: EVERY 30 SECONDS
POWER SOURCE: 12 VDC NON-REGULATED, NON-FILTERED ± 2 VOLTS
OPERATING TEMPERATURE: -10 TO +55 DEGREE C.
OUTPUT LOAD:
40 mA MINIMUM TO 1.5 AMP MAXIMUM FOR EACH OUTPUT
SAFEGUARDS: STATIC ELECTRICITY PROTECTION TO END USER AFTER INSTALLATION
ANTI-STATIC PACKAGING TO BE USED FOR SHIPMENT
SPIKE PROTECTION TO 400 VDC ON R+ TERMINAL
CONFORMAL COATING ON P.C. BOARD PROTECTION FROM MOISTURE
DEFAULT MODE: WHEN THE THERMOSTAT IS SWITCHED TO HEAT AND ELECTRIC HEAT IS
SELECTED ON THE SUB-BASE, AND THE OUTDOOR TEMPERATURE FALLS
TO A POINT AT WHICH THE HEAT PUMP SHUTS DOWN (USUALLY BETWEEN
25 - 40 DEGREES), THE SUB-BASE WILL AUTOMATICALLY ALSO CALL FOR GAS
FURNACE OPERATION IF THE INDOOR TEMPERATURE DROPS TO 45 DEGREES.
GAS FURNACE OPERATION WILL SHUT OFF AT 60 DEGREES. THE USER SHOULD
SWITCH THE SUB-BASE TO GAS HEAT IF THIS OCCURS.
GENERAL INFORMATION
A. Air Conditioner
This packaged heat pump mounts below the floor of the
vehicle. The innovative design makes it possible to maintain
a smooth, free-flowing roof line for the vehicle. It also
relocates all noise and condensate drainage off the roof to
below the floor of the vehicle.
The heat pump contains a dual compressor system. It
combines the capacity of two roof mounted units into one
highly efficient and compact package.
Each compressor is connected to a separate refrigeration
circuit. The system can be operated with a single compressor
when the air conditioning requirement is low, or with two
compressors when maximum performance is required.
This heat pump operates a two-stage system. The first
compressor and refrigeration circuit is referred to as “1
st
Stage”. The second compressor and refrigeration circuit is
referred to as “2
nd
Stage”. First and second stage will operate
as indicated below.
1
st
stage (the first compressor and refrigeration circuit), will
operate when:
1) The thermostat is demanding cooling or electric
heating,
2) The vehicle is being powered by either shore line or
the on-board generator.
2
nd
stage (the second compressor and refrigeration circuit),
will operate when:
1) The thermostat senses room temperature that is 2
degrees or higher than the setpoint temperature on
the thermostat,
2) The vehicle is being powered by the on-board
generator. Shore line by itself will not provide
enough power to operate both first and second stage
unless 50 amp service is available.
Switching and control of 1
st
and 2
nd
stage cooling is
automatic. When operating from shore line, the system
automatically limits operation to 1
st
stage only unless 50 amp
service is available. When the shore line is plugged into the
on-board generator, the system automatically allows for
