Mysa MYSA-V-1-0 Smart Thermostat User Guide

Welcome to the Mysa family! Thanks so much for supporting the Mysa Smart Thermostat. The device in front of you is the culmination of years of work by a diverse group of dedicated professionals located in the windy, rocky, but strikingly beautiful city of St. John’s, Newfoundland, Canada. It was amongst its cramped townhouses that we realized there just wasn’t an acceptable solution for those trying to build a smart home with electric heaters. We’ve since helped turn many homes into smart homes – and in the process we’ve also built a company, a wonderful product we’re very proud of, and a world class team. All with the goal of giving customers a way to conserve energy

High Voltage Warning

Installing this product involves handling high voltage wiring. Each step of the enclosed instructions must be followed carefully. To avoid fire, personal injury, or death, turn off your circuit breakers and follow the proper safety precautions before proceeding.
The installation of the thermostat must comply with the applicable Local and/or National Electrical codes and utility requirements. This installation should be entrusted to duly qualified personnel where required by law.

For the best installation experience, use the Mysa app. Download the Mysa app from the Google Play Store or iOS App Store and create an account or log in to your existing account. Tap on “Install & Support” then “Install” to access our most comprehensive step-by-step guide.

Warning

Turn off power at the circuit breaker that controls your existing thermostat.
- Double Check – After you turn off the breaker confirm the heater is off by doing the following:
- Turn the thermostat all the way up.
- Wait 5-10 minutes.
- Put your hand near the heater. Make sure no heat is coming through. If you have multiple heaters check each separately. If you are unsure if the power to your heater is off, please contact a licensed electrician.
Remove your existing thermostat. Only proceed with the installation if there are wire nuts connecting the thermostat wiring.

Setup 240V

Connect your Mysa Smart Thermostat using supplied wire nuts:
A. Connect Mysa’s white wire to the second phase leg of the circuit – L2 (usually red).
B. Connect Mysa’s black wire to the supply wire – L1 (usually black) coming from the electrical panel.
C. Connect Mysa’s red wire to the load wire (usually black) going to heater.
D. Connect Mysa’s green wire to the ground wire (usually green or bare copper).

The supply and load wires are not interchangeable. If you are unsure which of the two wires is the supply or load wire, simply try one configuration. If Mysa’s display doesn’t light up after finishing the installation, swap the supply and load wires.

Setup Using Wire Nuts

Introduction to Wire Nuts
Those little multi-colored caps that come in the box with Mysa are called Wire Nuts. You use them to connect 2 or more wires together. But you can’t just toss them on top of already twisted wires – there’s a safe and correct way to do it!

Connecting Wires

Start by holding the two wires together so that the copper ends are parallel.
Together, slip them into the Wire Nut.
Now, turn the Wire Nut clockwise until it feels secure.
Give the wires a gentle tug.
And if you detect any movement or slippage whatsoever, untwist and start the process over.

Secure Mysa

Unscrew the screw on the bottom of the front plate, but don’t remove it completely!
Remove the front plate to your Mysa to access the mounting screws
Using the supplied screws, mount Mysa to gang box by tightening screws Connect the front plate to your Mysa.
It should easily glide into place.
Secure the front plate to the Mysa by tightening the screw. Ensure not to over tighten the screw
Turn on the power at the circuit breaker that controls Mysa
