One or more polarity-sensitive phones exist on-site. Reverse the phone wires
connected to the brown and gray wire terminals on the RJ31X jack.
Light control issues
Light controlled by X10 lamp module is not working.
• Partition house codes are not programmed into panel. Enter program mode and
set partition house codes.
• Check that the HOUSE dial on the X10 module matches the partition house code
programmed into the panel.
• Panel is not powered by a power line carrier transformer. Replace existing
transformer with a power line carrier transformer.
• Check to make sure X10 module is not plugged into an outlet controlled by a
switch. Move to a nonswitched outlet location and test.
• Check that the lamp has a working bulb and that the lamp switch is on.
• Power transformer and X10 modules are not plugged into outlets on the same
electrical phase. Relocate modules or transformer to different outlets to
determine working locations.
Energy saver module issues
Module does not respond to system commands or appear to control furnace.
• Check that the module is wired correctly to the panel terminals.
• Verify the module LED is flashing continuously. If the LED is not flashing, remove
power and check wiring.
• There is a 5-minute delay after the module returns control to the furnace/AC
thermostat, before the module overrides the thermostat again. Wait 5 minutes
and try again.
Module temperature does not match actual room temperature.
The module room temperature setting has not been adjusted or was adjusted before
the module warmed or cooled to room temperature. To ensure accuracy, wait at
least 15 minutes after installing the module before adjusting the temperature. To
adjust the module room temperature setting, see Temperature under “Accessory
modules - bus device settings” on page 71.
