Installation - Electrical
If not factory-installed, the electrical contractor must
provide and install a starter or starting contactor,
disconnect, fuses, etc., as required by local codes, for the
CDQ wheel motor. Do not install a variable frequency
drive (VFD) to control the desiccant wheel speed. This

Optional Damper Actuators

Each actuator requires 24 Vac supply power and wiring for
the 2–10 Vdc control signal. This wiring should be sized

Optional Air Temperature Sensors

If not factory-wired, connection to the air temperature
sensors is made by penetrating through the side of the
module wall and making electrical connections to the
temperature sensor. Nominal resistance of these sensors
is 1,000 ohms at 32 degrees F (0 degrees C). The sensor is
