Once the thermostat is wired up, there are just a few more steps to finish the installation.
1. Attach the in-floor temperature sensor
Pull the temperature sensor wires through the hole in the back of the Mysa. Then, use a Phillips screwdriver to secure the Mysa to the gang box with the provided screws. Attach the two ends of the sensor wire into the two terminals by gently pressing down on the buttons using the small end of the screwdriver. It doesn't matter which wire attaches to which terminal as long as both are firmly secured.
2. Connect and secure the front plate of your Mysa. Secure it by tightening the screw. Do not overtighten the screw.
3. Turn power on to the Mysa.
4. Verify the thermostat is on, lights up, and displays a triangle.
