5.2B Wiring

WARNING: DO NOT ALLOW THE YELLOW LEAD FROM THE ULTRA-AIRE TO CONTACT THE RED OR WHITE LEADS FROM THE ULTRA-AIRE OR DAMAGE TO THE TRANSFORMER WILL RESULT

WARNING: UNPLUG ULTRA-AIRE BASE UNIT BEFORE WIRING CONTROL.

The installer must supply the wiring between the Ultra-Aire and the control panel. Be sure to safely route the control wires to prevent damage during installation. Be careful not to cross the wires when connecting the Ultra-Aire and the remote control panel or damage to the transformer may result.

The remote control of the Ultra-Aire is powered by a low voltage circuit (24 VAC) and must NEVER contact or be connected to a high voltage circuit. Some of the control wires leaving the Ultra-Aire may not be used with certain control panels and should be left safely disconnected with wire nuts taped onto the stripped ends. Be sure to consult the electrical schematic in this manual or on the front panel of the Ultra- Aire before making the control connections.
