Operating instructions

14
The dehumidify feature does not permit operation under the following conditions:
● Outdoor temperature is below 40 °F (4 °C). Resumes operation above 45 °F
(7 °C).
● Indoor temperature is below 62 °F (17 °C). Resumes operation above 65 °F
(18 °C).
● Indoor temperature is above 100 °F (38 °C). Resumes operation below 97 °F
(36 °C).
● When the zone with dehumidify is set to COOL mode and the indoor temperature
is 2 °F / °C above the COOL mode set-point. Resumes operation when indoor
temperature is 2 °F / °C below COOL mode set-point.
● When the freeze sensor temperature is 27º F (-3 °C) or less. Resumes when
freeze sensor temperature reaches 55º F (13 °C).
● If the system detects an error on any of the system temperature sensors.
When the system calls for furnace operation, the dehumidify feature will continue to
operate unless one of the conditions above occurs.
D. 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.
SPECIAL FEATURES
11
HIGH: The fan operates continuously at high speed. The compressor cycles ON
and OFF.
AUTO: When auto fan is selected the fan speed will vary depending on the differ-
ence between the temperature set-point and the room temperature. In auto fan the
compressor and the fan will cycle ON and OFF with the thermostat. The compressor
shuts OFF fi rst followed by the fan in approximately 15 seconds. For more informa-
tion on auto fan, see section, “A. Auto Fan” on page (13).
C. “HP” - Heat Pump Mode
In the HP mode the system will cycle the compressor ON and OFF based on the
room air temperature and the temperature set-point on the CCC 2 thermostat.
When the system calls for heating there will be a delay of approximately 2 minutes.
During this delay, the hour glass icon will be displayed in the LCD. In auto fan, the
compressor will turn ON fi rst followed by the fan in approximately 15 seconds. In
this mode there are (4) fan speed selections:
LOW: The fan operates continuously at low speed. The compressor cycles ON and
OFF.
MED: The fan operates continuously at medium speed. The compressor cycles ON
and OFF.
HIGH: The fan operates continuously at high speed. The compressor cycles ON
and OFF.
AUTO: When auto fan is selected the fan speed will vary depending on the differ-
ence between the temperature set-point and the room temperature. In auto fan the
compressor and fan will cycle ON and OFF with the thermostat. The compressor
shuts OFF fi rst followed by the fan in approximately 15 seconds. For more informa-
tion on auto fan, see section, “A. Auto Fan” on page (13).
D. “HS” - Heat Strip Mode
In the HS mode the system will cycle the heat strip ON and OFF based on the room
air temperature and the temperature set-point on the CCC 2 thermostat. In this
mode there are (4) fan speed selections:
LOW: The fan operates continuously at low speed. The heat strip cycles ON and
OFF.
MED: The fan operates continuously at medium speed. The heat strip cycles ON
and OFF.
HIGH: The fan operates continuously at high speed. The heat strip cycles ON and
