MODULE LOCKOUT FUNCTIONS
The Valiant FT control may lockout in either a manual reset condition requiring pushing the reset button to recycle the control
for a CSD1 requirement or an automatic reset condition. Pushing “RESET” with the control in a hard lockout condition is the
only way to reset the Valiant FT control. Turning the main power “OFF” and then “ON” or cycling the thermostat will not reset
a hard lockout condition. Wait until the display has synchronized before pushing “RESET” to clear a manual reset condition.
The Valiant FT control may proceed into a soft lockout condition. The boiler will stay in the automatic reset state until the fault
is corrected and will automatically return to normal operating state.
