Maintaining the temperatures of buildings, houses, offices and even locomotives is a big job. Weather and temperatures always fluctuate and this prompted the need for a smarter type of thermostat; one that could sense the rise or fall of the temperature and react accordingly. The Emerson Sensi Thermostat does just that.

Having temperatures at a pre-determined set value seems to be people’s preference these days. People have even come to expect it. The comfortability of guests and family members prompts many heads of households to seek out the latest and best thermostats available.  In my research to find out the best way to regulate temperatures, I found the White-Rodgers Emerson Sensi Thermostat.

Emerson Sensi Thermostat Description

White-Rodgers 1F86U-42WF Emerson Sensi Wi-Fi Thermostat

A thermostat is a device that keeps an area within a limited temperature range by automatically switching the supply of heat on or off. It senses the temperature of the area and adjusts it so that the temperature is maintained at or near a desired set point. Technology has made it possible for thermostats to be constructed in many ways by the use of various sensors to measure the temperatures at different  points, after which the feedback of the sensor is used to control the heating and cooling device.

White Rodgers Emerson Sensi Thermostat is the first Wi-Fi Thermostat to be released after a long period of research on the subject of wireless thermostats. The device has a simple design that makes its installation very simple. In addition to the simplicity of its installation, it is also very simple to connect it to the internet. It can be accessed from smartphones, tablets or a PC and does not require any wires for most applications. One does not have to be at home or near the device  in order for the thermostat to work. You can be across town and still regulate the temperature of your house.

      Sensi has five email alerts that will notify the customer when certain conditions occur. The alerts are automatic and will generate a second email if the condition still exits after a week. At this time, the alerts cannot be changed. Below is a list of the conditions that will generate an email alert:
      *High Home Temperature > 99ºF
      *Low Home Temperature < 45ºF *High Humidity > 78%
      *Loss of Heating – room temperature goes down 5ºF during a heating demand
      *Loss of Cooling – room temperature goes up 5ºF during a cooling demand
      Thanks.

    I’ve got 2 questions
    Is it possible to switch in Celcius degree and not only in °F ?
    is it possible to get the clock in 24h type or only on the 12hAM/PM ?

      Hi Jean Bon,
      1. Yes. You can select temperature display to F or C by Press HOLD to advance to next item or TIME to move backwards to previous item .
      2. Normally, the thermostat is set to display 12-hour time meaning AM/PM time. However, if you want to change display a 24-hour clock, you can press and hold SET TIME and RUNPRGM buttons at the same time .
      You can see how to install & download manual at here
      Thank you 🙂

      YES! You enter a password on setup (comes with unit, and can be changed) and have to enter the password on whatever device you watch to use to control it.

    If using a heat pump as primary heat with aux fossil fuel the sensi does not work properly. Stay away from SENSI STAT. IT WILL CREATE PROBLEMS FOR YOU AND DESTROY YOUR COMPRESSOR . They are not set up internally through the logitherium it has built into device. In eastern Canada they do not work properly. What a mess it can cause for home owner and H.V.AC.R COMPANY.Stick with what always works. HONEYWELL.

    For the Emerson Sensi thermostat, what happens to the thermostat if my WIFI goes out? Does it stay where it was set when the WIFI was on and my furnace continue to operate with current settings? Does the Thermostat revert to a common, traditional, manually operated thermostat? When the WIFI returns – what then happens to the thermostat and to my gas furnace?
    Thanks.
