Table N: LED Indicators

24.Upon sufficient flow from the heater pump, the flow switch contacts will close.

25.The flow light is energized; located on the diag- nostics panel.

26.A 24 VAC signal is also sent to the “TH” terminal located on the ignition module.

27.Once the 24 VAC “TH” signal is received at the ignition module, a 120 VAC signal is sent from F2 on the ignition module to the 120 VAC pilot duty terminals, located at J-14 on the circuit board.

28.The 120 VAC signal continues to the coil of the blower relay K-3 (N.O.).

29.The 120 VAC signal continues to the 120 VAC safety terminals located at J-13 on the circuit board.

30.When the coil on relay K-3 (N.O.) is powered, the relay contacts (K-3) close and energizes the blow- er from the J-8 connections on the CPW board.

31.After proper air pressure is received in the air plenum, the air pressure switch will close.

32.A 24 VAC signal is now sent to the blower LED on the diagnostics board.

33.Power is applied to the optional equipment inter- lock connection (normally jumpered).

34.The 24 VAC signal is then sent to the 24 VAC safe- ty connector.

35.24 VAC is now sent to the pressure switch (P.S.) terminal on the ignition module.
