17.DC VOLTAGE
A DC volt supply is required for operation of the Comfort
Control Center. The operating range is 10 to 16 volts DC. If
DC voltages are outside of the operating range, erratic op-
eration may result.
Use a DC voltmeter to check for the incoming DC voltage
between the red positive (+) and the black negative (-) at the
connections of the electronic control box. If no DC voltage
is found check the supply breaker or fuses.
Check the output voltage by using the telephone wall jack.
One end of the cable is plugged into the A/C power module
RJ-11 jack. The Comfort Control Center end is plugged into
the telephone wall jack. Use a DC voltmeter to test for DC
power between the red and black terminals. See FIG. 13
and 14. If there is no voltage present, check the control
cable. See Section B2.
