ERROR CODES
PAGE 35
IGNITION SAFETY: Protection for Ignition System
Error Code:
One beep every one second.
Description of Fault:
Warns users if pilot is not successfully ignited in 60 seconds.
How to Clear:
Press MODE button to OFF then to ON to re-attempt ignition.
What to Check:
Ensure gas supply is turned on.
Ensure orange/white leads from module are plugged into “PILOT” connection on valve body.
Verify lead from igniter on pilot assembly is connected to “I” terminal on main control module. (Clicking sound will also be
heard).
Verify lead from flame sensor on pilot assembly is connected to “S” terminal on main control module. (Pilot will light but ma
in burner will
not. Pilot will extinguish after 60 seconds and error code will alarm).
Verify black ground lead is connected to tab extending from valve bracket.
SENSOR SAFETY: Protection for Flame Sensor
Error Code:
Four beeps every one second.
Description of Fault:
Warns users pilot flame senor detects a pilot flame already present when ignition sequence is initiated. This fault will
also occur if pilot flame senor on main control module is shorted to ground.
How to Clear:
Press MODE button to OFF then to ON to re-attempt ignition.
What to Check:
Check if pilot flame is actually present when valve is turned OFF (if yes, replace valve).
Replace pilot assembly.
Replace module.
THERMAL SAFETY: Overheat Protection
Error Code:
Four beeps every two seconds.
Description of Fault:
Warns users that module‟s internal temperatures have exceeded 170
˚
F (77˚C).
How to Clear:
Module‟s internal temperatures must cool to below 160
˚
F (71
˚
C) and then press ON button.
What to Check:
Are modules located in an unapproved location. Move to cooler location.
COMMUNICATION SAFETY: Protection for Ignition System
Error Code:
One beep every four seconds.
Description of Fault:
Warns users the hand held remote and main control module are not communicating properly. This safety feature is
active in both manual and thermo modes. The remote control sends a communication safety signal every 15 minutes. If
the main control module does not receive this signal, it begins a 2-hour countdown. If no communication safety signal
is received at the end of this countdown, the system will enter communication safety shutdown which turns system OFF
and emits the error code.
What to Check:
Verify batteries in hand held remote control are new.
Ensure remote control is located within 20 ft. (6 m) of main control module.
Ensure remote control is not placed directly on top of or inside a metal enclosure as this can interfere with transmission.
