Controls; Wiring Controls - Trane EDHUM070H Installation & Operation Instructions

A control can be used with the EDHUM070H. Santa Fe offers the DEH 3000 proprietary control. The DEH 3000
monitors and controls relative humidity and proper ventilation levels in their home. This control is also available
with a remote sensing option. The EDHUM070H features a built-in dehumidistat control as well as the ability to
wire a remote mounted control to the unit. If the EDHUM070H is located outside of the area where humidity
control is desired, consider using a remote wired humidity controller that is located in the area where humidity
control is desired. If using the built-in dehumidistat to control the unit, locate the control in an area where it can
accurately sense the humidity of the area where humidity control is desired. If the EDHUM070H is located in the
area where humidity control is desired, consider using the built-in control. Adjust the humidity control so that
the unit maintains the desired level of humidity.
Note: The DEH 3000 is sold seperately and can be purchased online or through your local dealer. Other
thermostats are compatible with the EDHUM070H.

CAUTION! CAUTION!
DO NOT ALLOW THE 24V TERMINAL FROM THE EDHUM070H TO CONTACT THE COM
TERMINAL ON THE EDHUM070H OR DAMAGE TO THE TRANSFORMERS WILL RESULT.
Circuit Breaker
To prevent damage to the 24 volt control transformer, the EDHUM070H comes with
a resettable circuit breaker. Check wiring for any electrical short and repair before
resetting breaker. Resetting the circuit breaker without correcting the electrical short may
result in transformer damage. Be sure to check the electrical schematic in this manual
or inside the access panel of the EDHUM070H before making any control connections.
The reset button for the circuit breaker can be found on the back of the unit.
Control Connections
The control and the EDHUM070H are labeled to prevent confusion. Depending on the
control, some of the screw terminals on the EDHUM070H may not be used. Be sure
to consult the electrical schematic in this manual or inside the access panel of the
EDHUM070H before making control connections.
A low voltage control must be used with the EDHUM070H.

*
Between the COM lead and the 24V TERMINAL is a 40VA transformer. This low voltage power source
powers the relay coils which control the fan and compressors. This 24VAC transformer can also be
used to power HVAC accessories external to the dehumidifier.
