TROUBLESHOOTING

Check your power source using a Volt-Ohm meter; check the following voltages at TB1 terminal block:

TB1-1 to TB1-2 = 108 VAC Minimum, 132 VAC Maximum

TB1-1 to TB1-3 = 108 VAC Minimum, 132 VAC Maximum

TB1-2 to TB1-3 = Must be less than .6 VAC

IF CALL FOR HEAT LED does not illuminate when the heater has a CFH signal, check for 24VAC at the heater CPW Board (J17-TRIG) output. If voltage is present, check wiring using the wiring diagram. If volt- age is not present, the problem exists in the heater.

IF VALVE DOES NOT MOVE: Check for voltage out at

TB2-1: Should be a 1VDC to 10VDC output to the actuator valve. If no voltage is present, check for volt- age at TB2-3, there should be a 12VDC signal. If the 12VDC signal is not present, verify that the converter is wired correctly using the wiring diagram.

IF SENSOR OUT OF RANGE LED is illuminated: The set point temperature has not been reached within the 7 minute time period.

•Push the Reset Switch (see Fig. 4) or remove power and watch for proper operation.

•Check pump sizing and valve/piping sizing and cor- rect as necessary.

•Replace sensor.

•Check wiring using wiring diagram.
