Unit Setup
Once you've verified the unit option code using the
directions listed on the previous page, and you've
found that the option code does not correspond
with the actual model number stated in Table B,
you will need to change the unit option code.
Initializing the Control
Password 1818
If the control appears to be operating correctly but
there is no 3.5 - 5 VDC at the solid state relay across
4- and 3+, attempt to reinitialize the control before
replacing it. Perform this procedure the same as
you would to set the voltage or option code.
Instead enter 1818 and then hit start. The display
will go blank. Proceed to program the correct volt-
age and option code and test for power. If there is
still no power to the solid-state relay, check to verify
the wiring is correct. If everything checks out, the
control may be defective.
