Installation

1. mounting location. Choose a location on an interior wall near the air return grille, about five feet above floor level, where air circulation is good and temperature is average for the zone.
   avoid mounting the Indoor Remote Zone Sensor in areas such as:
   • Behind doors
   • On outside walls, or any walls with unheated or uncooled areas behind the zone sensor
   • In direct sunlight, or near any source of radiant heat that could affect the temperature measurements
   • In line with the discharge air from the unit being controlled
2. mount sub base. Remove the Zone Sensor cover from the subbase and mount the subbase on the wall or in a 2’ X 4” device box. Route the wires through the wire access hole in the sub base (see Fig. 22). Seal the hole in the wall behind the subbase.
