Page 26: Appendix B Using The Temperature Sensor With (Optional) Humidity
“Temperature + Humidity” Digital Temperature & Humidity Sensor The yellow or blue LED, depending on your model will turn on for 3 minutes when the e-Stat™ is turned on. This helps identify which sensor goes with which e-Stat ™ The #18-2 conductor wires which attach the sensor do not require shielding and are not polarized. - Page 27 You can choose a relative humidity “trigger point” remotely via the web based interface. (from 45% RH to 70% RH) Let’s choose 55% RH. In this example let’s assume that the e-Stat has been remotely pro- ™ grammed for a 74° F cooling setting.
- Page 28 Contact Closure Connection The e-Stat can be used to monitor a Contact Closure ™ such as a switch. Use #18 gauge 2-conductor twisted pair cable between the e-Stat and the switch or other open/closed con- ™ tact type device. Contact Closure is unaffected by wire runs of up to 500 feet.
