WARNING

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.

5.3 Operation

5.3A Display

When there is power to the control, the control display sequence will alternately show the clock, humidity, temperature, fan status, and fresh air damper status. The display sequence repeats continually, and is referred to as “home state”.

5.3B Setting

During the set-up process, if you make a mistake, you can always go back to adjust the settings. If you leave the control alone and don’t touch any buttons for 10 seconds, the control will remember any changes made and return to “home state.”

5.3C On/Off Setting

Press the “ON/OFF” button to turn the system on or off. When the system is on, the green indicator will be lit. In the off mode, the controller continues the regular display sequence and indicates current time, temperature, and relative humidity. It also displays the status of the fan and damper as if the control were on, but the fan and damper will not operate unless the control is on and the green indicator is lit. Setup can be done with the control either on or off.
