## What are the Sensi?

/ Japanese (ˈsɛnseɪ) / noun. a teacher or instructor, esp of karate or judo.

## Where does R wire go on Sensi?

The jumper wire connecting terminals RC and RH are most common, and this jumper wire is not necessary on Sensi thermostat. Sensi thermostat has a built-in RC/RH jumper wire on the back of the thermostat face plate.

**What is the difference between Sensi st55 and st55u?**

The st55u is a touch screen and has bluetooth. The st55 is not a touch screen and does not have bluetooth.

**How do I use Sensi app?**

Using the Sensi thermostat app, select the days you want to follow a specific schedule. Then choose the time and temperature set points for each. When you are running a schedule, scroll across the Thermostat Detail View on the home screen to see your scheduled temperatures for the next 24 hours.

### Can I use Sensi thermostat without C-wire?

The Sensi Wi-Fi Programmable Thermostat works on most combined heating and cooling systems without a c-wire. The Sensi Smart Thermostat also works on most combined heating and cooling systems without a c-wire, however, will require a c-wire for Apple HomeKit functionality.

### Why is my Sensi thermostat not getting power?

If you installed a Sensi Touch Smart Thermostat, but the touchscreen is still blank after completing all the steps in the Sensi app, then most likely the thermostat is not receiving enough power from your system to turn on. Sensi Touch requires a “C” wire to provide 20-30VAC to power the thermostat.

**Can I jump RH and RC?**

Putting more than one wire into a Nest thermostat connector can damage your system and your thermostat. Instead of using jumper wires, Nest Learning Thermostats use an internal jumper between the Rh and Rc connectors. A Nest Learning Thermostat will automatically use this internal jumper if your system needs it.

**Does Sensi WIFI need C-wire?**

The Sensi Touch Smart Thermostat always requires a c-wire.

#### What is an exponent calculator?

Exponent Calculator. Exponentiation is a mathematical operation, written as an, involving the base a and an exponent n. In the case where n is a positive integer, exponentiation corresponds to repeated multiplication of the base, n times. The calculator above accepts negative bases, but does not compute imaginary numbers.

#### When an exponent is 0 the result is 1?

When an exponent is 0, the result of the exponentiation of any base will always be 1, although some debate surrounds 0 0 being 1 or undefined. For many applications, defining 0 0 as 1 is convenient. Shown below is an example of an argument for a 0=1 using one of the previously mentioned exponent laws.

**What is the relationship between negative and positive exponents?**

Exponents with negative bases raised to positive integers are equal to their positive counterparts in magnitude, but vary based on sign. If the exponent is an even, positive integer, the values will be equal regardless of a positive or negative base.

**What is exponentiation?**

Exponentiation is a mathematical operation, written as a n, involving the base a and an exponent n. In the case where n is a positive integer, exponentiation corresponds to repeated multiplication of the base, n times. a n = a × a × × a. n times. The calculator above accepts negative bases, but does not compute imaginary numbers.
