Problems to Look for:
•
Mis-wire/short/open
•
Excessive resistance in circuit (corroded or loose
connection)
•
Setpoint lever inaccurate (should be +-2F of chart)
•
Induced voltage (high voltage wires in same
conduit)

Mode Input
Terminals to Read Voltage: RTRM J6-4, J6-2
Read DC voltage with Zone Sensor Module (ZSM)
attached. If voltage read does not appear to be correct,
read the resistance of the circuit, then the ZSM itself, to
see if a problem exists in the ZSM or the wiring. With
the ZSM not attached there should be 5.00 VDC at the
terminals listed above. To check for induced voltage,
read AC voltage to ground from each sensor wire.
Should be less than 2VAC.
