System failure 30 indicates: Mains voltage reading LV1 is outside of the expected range.
Cause(s)
Mains Voltage Comp Circuit is not calibrated
correctly.
High or low mains voltage. This failure is triggered
if the mains voltage is outside the following
ranges:
• 100V: 80-115V
• 115V: 95-132V
• 230V: 195-270V
Defective 50 pin ribbon cable between the relay
and control board.
Defective relay board.
Defective control board.

4.4.26 System Failure 33

System failure 33 indicates: Defective RH Solid State Relay.
Cause(s)

Action(s)
Calibrate the line voltage.
Connect to proper mains voltage source
Check for continuity on pin 48 and 49 (LineComp1,2) If
defective replace cable.
Measure the voltages at the relay board:
• J37 pin 48-45 and J37 pin 49-45.
• If mains voltage 100/115 = 3-5 volts, difference
within 0.4 volts.
• If mains voltage 230 = 7-10 volts, difference within
0.8.
• If not, replace the relay board.
If the voltages are OK, replace the control board.
Action(s)
Replace relay board
Action(s)
This error may occur after replacing the control/display
board. Be sure to install the software provided in the
control/display board. Replace the System Software.
