TROUBLESHOOTING
MAIN CONTROL MODULE WILL NOT LEARN TRANSMITTER
Ensure REMOTE/OFF switch on side of main control module is set to REMOTE.
Make sure batteries in both the hand held remote and backup battery pack are installed in the proper direction and are not drained.
Verify hand held remote indicates a signal is being sent. The LCD display should indicate ON or OFF depending on which button is
being pressed. The LED indicator should illuminate on wall transmitters and on/off transmitters. Buttons should be pressed and held
for 1 to 2 seconds to ensure a complete signal is sent.
Ensure 4-pin lead-
set is securely connected from battery pack to main control module‟s AUX connection. If the A/C adapter is use
d,
check that leads from adapter are securely connected to POWER terminals on main control module.
Press and hold LEARN button on main control module for approximately 10 seconds to clear memory (you should hear a series of
beeps from the receiver), immediately press either the ON or OFF button on hand held remote (you should hear a series of beeps
indicating the transmitter code has been learned).
PILOT WILL NOT LIGHT / STAY LIT
Verify gas supply is turned on.
Verify main control module is receiving signal from hand held remote by listening for a beep from receiver when ON is pressed on
hand held remote. If you do not hear a beep, ensure main control module has learned the hand held remote. (See above).
Ensure black lead from pilot assembly igniter is securely connected to terminal labeled „I‟ and red lead from flame rectifica
tion
sensor is securely connected terminal labeled „S‟ on main control module.
Make sure black cap leads marked PILOT from main control module are securely connected to terminals labeled PILOT on valve
body.
Ensure black GROUND wire is securely connected to tab located next to ON/OFF toggle switch.
A proper ground is essential to
spark igniter operation.
Make sure pilot flame is in contact with flame rectification sensor on pilot assembly. This valve is equipped with a pilot flame
adjustment screw. If pilot flame is too small it will not contact flame rectification sensor and will not complete the safety circuit.
Check continuity of pilot on valve. Remove wire connector. If there is no continuity on pin terminals, replace valve.
PILOT FLAME ALWAYS ON / WILL NOT EXTINGUISH
Ensure continuous pilot icon is not present in LCD screen. If icon is present, press PILOT button. This will de-activate the continuous
pilot feature and the icon will disappear from LCD screen.
PILOT BURNING BUT IGNITER CONTINUES TO SPARK
Check that flame sensor is fully impinged by pilot flame. If needed, adjust pilot.
Check end-to-end continuity of sensor. If sensor has continuity, replace module.
