The transformer is located in the control panel. The circuit
breaker is located on the left side of the transformer and
can be reset by pressing in on the black reset button.
Controls using 24 Vac
Before installing any connecting wiring, refer to
for the electrical access locations
provided on the unit and
for AC conductor
sizing guidelines.
1.
Use copper conductors unless otherwise specified.
2. Ensure that the AC control wiring between the controls
and the unit’s termination point does not exceed three
(3) ohms/conductor for the length of the run.
Note:
Resistance in excess of 3 ohms per conductor could
cause component failure due to insufficient AC
voltage supply.
3. Be sure to check all loads and conductors for grounds,
shorts, and mis-wiring.
4. Do not run the AC low voltage wiring in the same
conduit with the high voltage power wiring.
5. Route low voltage wiring per illustrations on
the next
page.
NOTICE:
Use Copper Conductors Only!
Unit terminals are not designed to accept other types of
conductors. Failure to use copper conductors could
result in equipment damage.
