FAILURE TO LIGHT – RETRY:
If the rst ignition attempt fails during a normal heating cycle the control will make two (2) additional
ignition attempts:
1. The control de-energizes the gas valve after the 4-second ignition trial ends.
2. The control operates the blower during a 30-second post-purge period.
3. The control monitors for open contacts at the blower vacuum switch.
4. The control performs a gas valve relay check.
5. A normal ignition sequence resumes with Item #2 in “Heating Mode” (above). If the third ignition
trial fails the control enters a safety lockout (or “hard” lockout) after the postpurge period of the
third failed trial.
6. The error code “IF” is displayed and the “SERVICE” indicator is illuminated.
a. The control automatically resets and clears the “IF” error code without any user intervention after
60 minutes. If there is a call for heat after reset the control will make three (3) trials for ignition. If
ignition is not established the control will again enter safety lockout for 60 minutes. This cycle will
continue until ignition is established or the call for heat is removed.
b. The user can reset the control and clear the “IF” error code by pressing the “MODE” button to
move through “STANDBY” and return to the previous mode (“SPA” or “POOL”).
LOSS OF FLAME – RECYCLE:
If ame is established and then lost, the control will make ten (10) attempts at ignition. If ame is lost
within ten (10) seconds of ignition the control will respond within 2 seconds. If ame is lost more than ten (10)
seconds after ignition the control will respond within 0.8 seconds.
1. The control de-energizes the gas valve and the blower.
2. The control monitors for open contacts at the blower vacuum switch.
3. The control performs a gas valve relay check.
4. A normal ignition sequence resumes with Item #2 in “Heating Mode” (above).
5. If the tenth ignition trial fails the control enters a safety lockout (or “hard” lockout) after the post-
purge period of the tenth failed trial.
6. The error code “IF” is displayed and the “SERVICE” indicator is illuminated.
a. The control automatically resets after 60 minutes. If there is a call for heat after reset the control
will make three (3) trials for ignition. If ignition is not established the control will again enter safety
lockout for 60 minutes. If ame is established but is lost the control will make ten (10) attempts at
ignition. This cycle will continue until ignition is established or the call for heat is removed.
b. The user can reset the control and clear the “IF” error code by pressing the “MODE” button to move
through “STANDBY” and return to the previous mode (“SPA” or “POOL”).
KEYPAD INPUTS:
The control accepts user inputs via the keypad on the front panel.
1. When changing the mode from “STANDBY” to either “SPA” or “POOL” there may be up to a 10-
second delay for the blower fan to begin running. The control performs an internal self-test and then
veries that the blower vacuum switch contacts are open before energizing the blower.
2. It is normal for the heater to display a 1- to 2-second delay in responding to any keypad input.
3. It is normal for the heater to display up to a 5-second delay when the keypad is used to reset the control
to clear an error code.
4. The control will accept a mode change during lockout after 5 seconds. The control will continue to
display the error code and remain in lockout until it is reset. At reset the control will go to the last saved
mode.
