Field Installed Control Wiring
The Rooftop Module (RTM) must have a mode input in
order to operate the rooftop unit. The flexibility of
having several system modes depends upon the type
of sensor and/or remote panel selected to interface
with the RTM. An overall layout of the various control
options available, with the required number of
conductors for each device, is illustrated beginning
with Figure 59, p. 86.
NNoottee:: All field wiring must conform to NEC guidelines
as well as state and local codes.

The various field installed control panels, sensors,
switches, and contacts discussed in this section require
both AC and DC consideration. These diagrams are
representative of standard applications and are
provided for general reference only. Always refer to the
wiring diagram that shipped with the unit for specific
electrical schematic and connection information.
Controls using 24 VAC
Before installing any connecting wiring, refer to Figure
16, p. 39 for the electrical access locations provided on
the unit, and Table 41, p. 80 for AC conductor sizing
guidelines. Then check the following:

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.
NNoottee:: Resistance in excess of 3 ohms per conductor
may cause component failure due to insufficient
AC voltage supply.
3. Make 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.
Controls using DC Analog Input/Outputs
Before installing any connecting wiring between the
unit and components utilizing a DC analog input\output
signal, refer to the appropriate illustration in Figure 16,
p. 39 for the electrical access locations provided on the
unit and Table 42, p. 80 for conductor sizing guidelines.

1. Use standard copper conductor thermostat wire
unless otherwise specified.
2. Ensure that the wiring between the controls and the
unit termination point does not exceed two and a
half (2.5) ohms/conductor for the length of the run.
NNoottee:: Resistance in excess of 2.5 ohms per conductor
can cause deviations in the accuracy of the
controls.
