Page 10: Remote Sensor Installation
Remote Sensor Installation The e-Stat must have both a remote temperature sensor and a supply air sensor installed. These sensors are supplied for each thermostat. Note: See Appendix B for remote temp and humidity sensor. Use #18 gauge 2-conductor thermostat cable between the e-Stat and the remote sensors. - Page 11 Supply Air Sensor Mount the Supply Air Sensor on the discharge air duct with the probe in the discharge air stream. The probe must be positioned horizontally or downward. Do not place on the bottom of the duct with the probe sticking up.

If the temperature buttons function and they are used, the word “OVERRIDE” will appear in the display. The override period is determined by the communications interface. When the override period expires, the e-Stat will revert back to its program. e-Stats Note: Not all allow button adjustment of temperature settings during the OCCUPIED period. - Page 20 Output Status e-Stat Your will show the status of the HVAC system outputs.
