SYSTEM
General
RADVTSC models are equipped with the Signature Com-
mand control valve (Figure 48) which operates on 6 volts.
The A/C module plugs into the stove junction box A/C power
supply. Four (4) “AA” batteries are used for back up during
power outages.
The Signature Command System can also be operated
without A/C power. The system can run on four (4) “AA” bat-
teries for approximately six (6) months under normal use.
A/C power must be used to power the A/C module and
blowers.
