5.3B Setting
Warning: Connecting the white wire to the control terminal without use of a motorized damper could create a short resulting in damage to the transformer.
The white wire controls the motorized damper that can be installed into a fresh air duct. This provides the ability to control when fresh air is introduced into the building by using the ventilation timer function labeled “damper” on the control. If the motorized damper is not used, DO NOT CONNECT THE WHITE WIRE TO THE CONTROL OR DAMAGE TO THE TRANSFORMER MAY RESULT. Simply leave the white wire terminal (Y1) unused if the damper is not used.
5.2C Location
Install the remote control panel in a central area of the structure where it will sense the relative humidity of the structure accurately. Do not install the control panel where it may not accurately sense the relative humidity such as near HVAC supply registers, near exterior doors and windows, or near a pool or spa.
