2.12 FIELD CONTROL WIRING
Each unit is fully wired from the factory with an internal operating control system. No field control
wiring is required for normal operation. However, the C-More control system used with all
Innovation Heaters does allow for some control and monitoring features. Wiring connections for
these features are made in the Input/Output (I/O) Box. The I/O Box is located on the upper-left
portion of the unit front panel (Figure 2-11) behind the removable front panel door. To access
the I/O Box terminal strips shown in Figure 2-11, loosen the four cover screws and remove the
cover. All field wiring is installed from the rear of the panel by routing the wires through one of
the four bushings provided.
Refer to the wiring diagram provided on the cover of the I/O Box (Figure 2-12) when making all
wiring connections.
