Zone Control; Program "1" & "2 - Dometic 3314080.000 BLACK Operating Instructions Manual

B. Zone Control
Zones are established at the time of the installation of your Dometic CCC 2 thermo-
stat. A zone is an area of cooling/heating which is controlled independently by the
CCC 2 thermostat. The CCC 2 thermostat allows for four zones (Air Conditioner/
Heat Pump) to be set up and run independent of each other. If you have one air
conditioner/heat pump installed, you will have one zone. If your RV has more than
one cooling/heating system, you may have two, three, or four zones.
Your CCC 2 thermostat will operate cooling and heating appliances that your vehicle
manufacturer has designed to cool or heat specific areas (zones) of your RV. The
CCC 2 thermostat will advise you of the number of zones in your RV. The zones are
displayed "1", "2", "3", or "4" in the LCD readout. See section, "D. Quick Reference
To LCD Icons" on page (5).
In the event your vehicle has multiple zones designed, you have the freedom of
selecting different modes of operations for each zone. To change from one zone to
another, press the ZONE button on the CCC 2 thermostat. Each time the button is
pressed and released the indicator will change the zone data displayed. When the
zones have been programmed, the zones in operation will be displayed. To program
each zone, simply repeat the programming steps shown under main heading, "Pro-
gramming & Operations" on page (6).
C. Program "1" & "2"
The Dometic CCC 2 thermostat can store two operating programs. Each program
can be set on individual zones with different mode and time settings for each zone.
For each event the user can program the operating mode, fan speed, temperature
set-point, and the time of day for the event.
1. Select the zone to be programmed.
2. Select program "1" by pressing the PROGRAM button. "PROG 1" icon will blink
on the LCD display.
3. Press the CLOCK button to set the time of day for program to start.
4. Press the MODE button to select the mode of operation.
5. Press the FAN button to select the fan speed.
6. Press the PROGRAM button to save the "PROG 1" settings. LCD will now dis-
play "PROG 2".
To set program "2", repeat steps (3) through (5).
7. Press the PROGRAM button again to save program(s) in memory.
Depending on the time of day, program "1" or "2" will begin immediately.
For instance, if program "1" is set to begin at 10:00 AM and the time of day
is 10:30 AM, program "1" will begin immediately. On the other hand, if pro-
gram "1" is set to 10:00 AM and program "2" is set to begin at 6:00 PM and
the time of day is 7:00 PM, program "2" will begin immediately.
