8.Delay-On Relay - Once the Delay-On (Low Fire Hold) Relay has timed out, it energizes the Modulation Release Relay (SPDT) to enable the analog signal from the TempTrac to the VFD to regulate the speed of the blower.

a.The TempTrac will continue to monitor the stored water temperature in the tank.

b.When the setpoint temperature is reached the call-for-heat signal to the flame safeguard control is discontinued.

c.The flame safeguard control deenergizes the VFD blower system and the gas valve, thereby suspending burner operation.

d.As heat is transferred to the building, the water heater loop temperature will fall below the set point. The TempTrac will sense this condition and begin the call-for-heat sequence again.

9.Flame Safeguard LED Diagnostic Indicator - If the Fenwal Flame Safeguard Control at any time during the operating sequence senses an improper operating state and locks out, the diagnostic red LED located on the control board will flash to indicate one of the following conditions exist:
