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.
UNSURE ABOUT HANDLING ELECTRICAL WIRING? CONSULT A QUALIFIED ELECTRICIAN.
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.

Ground Fault Circuit Interrupter (GFCI)

In the event of a ground fault, a GFCI will trip and quickly stop the flow of electricity to prevent serious injury. During a ground fault, current flows through an unintended path (like a human body) to the ground, instead of its normal safe path.
A GFCI does not protect against circuit overloads, short circuits, or shocks.
A GFCI is a fast-acting circuit breaker designed to shut off electric power in the event of a ground fault, which can help reduce the effects of an electrical shock.

Mysa In-Floor Safety Features

The TEST button manually tests the GFCI’s ability to respond to a fault. If working correctly, pressing this button should activate the FAULT light and disconnect the heat indefinitely, until the Mysa is power cycled or the RESET button is pressed.
If the GFCI is no longer able to safely detect a current it will disconnect the heater load and the fault light will be activated indefinitely. If this occurs immediately after installation, please contact technical support at help.getmysa.com.

Critical Installation Information

Should you install it?
Installing a GFCI thermostat can be more complicated than installing a conventional thermostat.
Make sure that you have experience wiring circuits, understand basic wiring principles and techniques, and can interpret wiring diagrams. Once completed, make surethat you have wired the GFCI protected thermostat correctly through the test button.
LINE vs. LOAD
A cable consists of 2 or 3 wires.

  • LINE Cable
    Delivers power from the electrical panel (breaker panel or fuse box) to the thermostat. This cable should be connected to the thermostat’s LINE terminals only.
    Mysa Smart Electric Baseboard Thermostat-fig.5
  • LOAD Cable
    Delivers power to the heater. This cable should be connected to the thermostat’s LOAD terminals only.

Warning – Turn Off the Power

  1. Turn off the power before completing any electrical installation, locate your electrical panel and find the breaker that protects your in-floor heating circuit. Place the breaker in the OFF position.
  2. Confirm the heater is off by doing the following:
    • Turn the thermostat all the way up.
    • Wait 5-10 minutes.
    • Put your hand on the floor and make sure no heat is coming through.
  3. Remove your existing thermostat.Mysa In-Floor Electric Heat Thermostat-fig.6
    If you are unable to confidently identify the heating circuit’s corresponding breaker/fuse, or are unsure if the power to your heater is off, stop work and call an electrician to complete the installation. 1 2 3
  4. Loosen the screw on the bottom of the front plate, but don’t remove it.

  5. Remove the front plate to your Mysa to access the mounting screw holes.
  6. Identify the cables/wires before wiring, and identify the panel and heater connections.
    Connect your Mysa using the supplied wire nuts:Mysa In-Floor Electric Heat Thermostat-fig.8
    The supply and load wires are not interchangeable. If Mysa’s display doesn’t light up after finishing the installation, you may have wired the supply connections to the load connections or vice-versa. Re-check the wiring and then swap the supply and load wires if necessary.
    Setup • 120 V

    Setup • 240 V
    Identify the cables/wires before wiring, and identify the panel and heater connections.
    Connect your Mysa using the supplied wire nuts:

    The supply and load wires are not interchangeable. If Mysa’s display doesn’t light up after finishing the installation, you may have wired the supply connections to the load connections or vice-versa. Re-check the wiring and then swap the supply and load wires if necessary.Mysa In-Floor Electric Heat Thermostat-fig.11
  7. Attach the In-Floor Temperature Sensor
    Pull the temperature sensor wires through the hole in the back on 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 and tighten the two screws with a small flat head screwdriver. It doesn’t matter which wire attaches to which terminal as long as both are firmly secured.

  8. Connect the front plate to your Mysa. It  should easily glide into place.

  9. Secure the front plate to the Mysa by tightening the screw. Ensure not to overtighten the screw.
    Power on Mysa
  10. Turn ON the power at the circuit breaker that controls the Mysa.

  11. Verify the thermostat powers ON, lights up, and displays a triangle.

Test Your Work

Why perform this test?

If you miswire the GFCI, it may not prevent personal injury or death to a ground fault (electric shock). If you mistakenly connect the LINE wires to the LOAD terminals, the thermostat faceplate will not illuminate after installation.
If you need assistance, please contact our support team on help.getmysa.com.

Procedure

  1. Verify the thermostat’s fault light is off. If it is on, press the RESET button.
  2. Turn the heater on to the maximum temperature setting, and wait 10 minutes.
  3. Press the TEST button. If the fault light illuminates and after 5-10 minutes the floor heater cools off, you have installed the thermostat correctly.
  4. press the TEST button (then RESET button) every month to assure proper operation.
