If a DC voltage reads 4.5 to 5V, the SSR is receiving
a signal to turn on the zone. If no voltage is present,
verify the continuity of the wiring between the HC1-X
or HC2 controller remote terminal and SSR board #
681686-1. If all the wiring checks out, the controller
itself may be faulty and should be replaced.
c. The next step is to check SSR output. Using a
voltmeter set to AC voltage scale greater than or
equal to voltage input of the machine, probe terminals
1 and 2. If voltage reading is equal to machine input
voltage, the SSR is not conducting and should be
replaced (
See
Maintenance Procedures
). If no
voltage is read on the meter, the SSR is functioning
properly.
2. Verify that the blower motor for the suspect zone is functioning. If
it is not, see
Troubleshooting Guide, section X
.

IV. Computer reports
a high deviation of a
heat zone or a zone
overheating.

A. Software
5. Choose
Channel setup from the Window menu. Select the
Heat zone channel in question using arrow key. (A typical
alarm screen for a heat zone is shown in
figure 8
).
