Santa Fe ULTRA70 Installation & Operation Instructions Santa-Fe-Products.com | 800.533.7533
A control can be used with the Santa Fe Ultra70. Santa Fe oers 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 Santa Fe Ultra70 features a built-in dehumidistat control as well as
the ability to wire a remote mounted control to the unit. If the Santa Fe Ultra70 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 Santa Fe
Ultra70 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 Santa Fe Ultra70.
