 If display reads “Prob”, Ω test the temperature probe. Check the wires and connectors between the probe and
controller for continuity.
 If display reads “Prob” “HI”, Ω test the temperature probe, and the wires and connectors between the probe
and controller for a short.
 If display reads “drn” “tUrn” “oFF”, verify that the drain valve is closed, check the proximity switch on the
drain valve.
Primary Solid State Control
NOTE: All controller test points are at connector P/J3 (the 12 pin connector at the controller).
24 VAC is supplied to the controller at pin #1(24VAC supply) and pin #5 (24 VAC input from DVI).
With the controller turned on, there is a 24 VDC output at pin #9 (SO) and the green indicator is illuminated.
When the controller calls for heat, there is a 24 VDC output at pin #8 (HD), the yellow indicator on the left is
illuminated, and there is a 24 VAC input at pin #6 (HFB).
When the controller receives the 24 VAC input at pin #6, the yellow indicator on the right is illuminated. If the
controller does not receive the 24 VAC input at pin #6, the indicator is not illuminated. This indicates a break in
the HD or HFB circuit.
To correct, do the following:
1. Check the hi-limit switch. Is it open or tripped?
2. Check the ignition module (sensing pilot flame, locked out, 24 VAC at MV terminal).
3. Check the HD relay on the relay board. Is the HD relay energized continuity through COM and NO contacts?
 If the green and yellow indicators on the left are illuminated and then shut off when the controller is turned
on, this indicates an open or shorted probe or wires in between the probe and the controller.
 If none of the indicators illuminate when the controller is turned on, verify that the drain valve is closed and
that the magnetic proximity switch has continuity when the drain valve is closed. Also verify that there is 24
VAC at pin #1 (24 VAC supply) and pin #5 (24 VAC input from DVI).
Backup Solid State Control
The backup solid state control works the same as the primary solid state control, with the exception of the 24
VAC supply passing through the solid state backup transfer switch to the computer or solid state digital control.
If the transfer switch is set to backup or if the backup controller is unplugged, the primary controller does not
work. The jumper must be installed on the relay board (connection J33) to allow the primary controller to function
if the backup controller is removed.
