G. Control Module Operation
1. The control module has an ON/OFF/REMOTE selector
switch that must be set. See Figure 13.4.
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 installation, fuel conversion,
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 continuously
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 commands from
an optional wired wall switch and/or one of the optional
wireless remote options.
2. An wall switch can be wired into the control module
brown and red wires.
3. 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 13.4. 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 seconds. After
this 10-second period, the fl ame can be adjusted from
HI to LO with the switch.
4. The control module has a safety feature that automatically
shuts down the fi replace after nine hours of continuous
operation without receiving a command from the wall
switch or optional remote.
5. If you intend to use both a wired wall switch and an
optional remote control to operate your fi replace, the
wall switch will override any commands given by the
remote.
6. 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
optional 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.
