SMART BOARD

"SMART BOARD" is the name of the new printed circuit board in your heater. The purpose of this new board is to simplify the procedure for checking out the heater in case of a malfunction. "SMART BOARD" uses a series of lights to check for power at various locations in the heater circuit. Lights that are lit have power going to those components or loca- tions, lights that are not lit indicate a lack of power at the terminal or location. During the operation of the heater, some check points should have power and some should not have power. The lights are num- bered (1 through 7, A and B). Following is informa- tion to help identify which lights should be lit, what problem may exist and explain the operation of the

SMART BOARD.

If a problem should occur, by following the instructions, the reason a heater does not maintain flame should be easily deter-

mined. As with any trouble-shooting, do not put ANYTHING inside the electrical box when the unit has power supplied to it. Be sure power is discon- nected at the breaker before servicing.

If the heater unit does not operate properly, remove the electrical box cover and look at the Auto-Check board. By looking at the lights on the board, the problem should be easily identified. With the on- off switch on, determine which lights are lit and which are not.

Standard Heaters ( not HI-LO fire):

When standard heater units are first turned on the and the purge time is completed (10 seconds), auto-check lights #1 through #6, A and B should be lit. When flame is established A and B will drop out. Light #7 is used only on HI-LO fire units and does not function on standard units.

HI-LO Fire Heater

On HI-LO fire units, all of the light sequences are the same as on standard units, except light #7 will be lit on high flame, and goes out when switching to low flame.

When the plenum chamber reaches the preset tem- perature of the humidistat-thermostat, lights 1 and 2 will be lit all other lights will be out. Once the flame goes out, light A will be lit and after the purge delay, lights 3 and 4 will be lit also. When the plenum chamber cools to the point of requiring more heat, lights 5 and 6 will be lit again. The cycle should continue until the unit is shut off.

The information below lists the light number(s) and what they indicate. Follow the chart down to the appropriate condition the unit is in, then read across to the explanation. Once the problem has been identified, you can proceed to fix the problem.

NOTE: Remove power and inspect all electrical connections before any other troubleshooting. If any connections are loose, tighten them and retry opera- tion.
