Wiring Applications (Examples)
Fig. 13 through Fig. 19 illustrate controller wiring for the
following configurations.
Typical controller wiring for VAV application using the
CLCM4T111 Wall Module and an LF20 Air Temperature
Sensor (see Fig. 13).
Typical controller wiring for VAV application with staged
reheat (see Fig. 14).
Typical controller wiring for PWM reheat and PWM
peripheral heat valve actuator (see Fig. 15).
Typical controller wiring for AHU application (see Fig. 16).
Typical controller wiring for 4…20 mA enthalpy sensors
and digital inputs (see Fig. 17).
Typical controller wiring for 4…20 mA heating, cooling,
and model ML6161 floating motor control (see Fig. 18).
Typical controller wiring for a pneumatic transducer, model
RP7517B (see Fig. 19).

shown) for typical VAV application
NOTE 1:
Earth ground wire length should be held to a
minimum. Use the heaviest gauge wire available,
up to 14 AWG (2.0 mm
2
), with a minimum of 18
AWG (1.0 mm
2
), for earth ground wire.
NOTE 2:
Contacts must be suitable for dry switching, 5 V at
10 mA. Use sealed type, gold-flashed, or pimpled
contacts.
