This completes the digital, analog, and LCD thermostat
unit installation. (Proceed to section K to complete the CCC
and CCC 2 thermostat installation)
Verify that all features of the system work. See digital,
analog, or LCD thermostat Operating Instructions or User's
Guide. Reconnect the 12 VDC and 120 VAC power sup-
plies. Check fan speeds, cooling mode, heat pump mode,
and furnace mode (if connected). If features do not work,
disconnect the 12 VDC and 120 VAC power supplies and
verify that all wiring is correct.
K. System Configuration, Reset & Check Out
(CCC and CCC 2 Thermostat Only)
Now that the system is installed, it is necessary to do a
system configuration, reset and check out.
1. Electronic Control Configuration
Depending on the equipment options installed by the
recreational vehicle manufacturer, the appropriate
dip switches will need to be switched to the "ON"
position. Placing the switch in the "ON" position
selects that option. See FIGS. 21, 22 & 23.
Note:
Dip switches are in the "OFF" position when shipped
from the factory except on heat strip and (heat pump CCC 2
only) models. On these models the appropriate dip switch,
heat strip or (heat pump CCC 2 only), is in the "ON" posi
-
tion from the factory. To gain access to the dip switches,
the outside plastic shroud must be removed from the unit.
Next remove the electrical box cover. The electrical box
will be on the curb side of the RV after installation. See
FIGS. 21, 22 & 23.
