F Control Module Operation
1.
The control module has an ON/OFF/REMOTE selector
switch that must be set. See Figure 12.3.
OFF Position: Appliance will ignore all power inputs
and will not respond to any commands from a wall
switch or remote. The unit should be in the OFF
position during installation, service, battery instal-
lation, and in the event that the control goes into
LOCK-OUT mode as a result of an error code.
ON Position: Appliance will ignite and run continu-
ously in the HI fl ame setting, with no adjustment in
fl ame output. This mode of operation is primarily
used for initial installation or power outage operation
with battery backup.
REMOTE Position: Appliance will initiate com-
mands from an optional wired wall switch and/or
the wireless remote (RC300).
2. If using a wired wall switch with the module in REMOTE
mode, the fl ame output can be adjusted with the HI/LO
selector switch on the module. See Figure 12.3. Note
that the fl ame HI/LO selector switch will become inac-
tive once an optional remote control (RC200/RC300)
is programmed to the control module. Note that the
control module will always ignite the fi replace on HI
and remain so for the initial 10 seconds of operation.
If the HI/LO is switched to the LO position, the fl ame
output will automatically drop to the lowest setting after
the fl ame has been established for 10 sec. After this
10 second period, the fl ame can be adjusted from HI
to LO with the switch.
3. The control module has safety feature that automati-
cally shuts down the fi replace after 9 hours of continu-
ous operation without receiving a command from the
remote.
4. If you intend to use both a wired wall switch and the
RC300 remote control to operate your fi replace, the
wall switch will override any commands given by the
remote.
5. The module has the capability to recognize potential
malfunctions. If these occur, it will fail to ignite and/or
respond to a command to ignite via the wall switch
and/or remote. In this case, the module may have
gone into LOCK-OUT mode. In this state, it will emit
a RED/GREEN LED error code. To reset the error
code, switch the selector to OFF, and then back to
REMOTE or ON. If the ignition command again fails,
the module will emit an LED error code, prior to going
back into LOCK-OUT mode. Contact your dealer for
service if this occurs.
