- Page 22 9. FENWAL DSI: SEQUENCE OF OPERATION / FLAME RECOVERY / SAFETY LOCKOUT Power Up / Stand By Upon applying 24 volts power to 24VAC, the control will reset, perform a self check routine, initiate full time flame sensing, and enter the thermostat scan state. Heat Mode When a call for heat is received from the thermostat supplying 24 volts to TH, the control checks the pressure switch for normally open contacts.
- Page 23 Flame Fault If at any time the main valve fails to close completely and maintains a flame, the full time flame sense circuit will detect it and energize the combustion blower. Should the main valve later close completely removing the flame signal, the combustion blower will power off following the optional post purge period.
