Before considering a Mysa Smart Thermostat for your baseboard heating, it's essential to confirm the electrical compatibility to ensure a seamless and safe installation.

1. Electrical Requirements for Mysa for Baseboard:

Power Supply: Mysa requires a dedicated 120V or 240V circuit, with a maximum breaker size of 20A, directly powering the unit.
Wiring Needs: A minimum of four wires is necessary in the gang box, two for the power supply and two leading to the heater.
Unit Specifications: Mysa supports up to 16A/3800W at 240V or 16A/1900W at 120V for each thermostat, with no digital built-in controls on the heater(s).

2. Heater Compatibility

Mysa is compatible with:

Fan-forced Heaters: Including toe-kick and electric fan heaters.
Radiant Heaters: Both in-ceiling and electric baseboard varieties.
Self-contained Hydronic Heaters: Popular brands like Cadet Softheat and Fahrenheat.
Convection Heaters: Efficient for even heat distribution.
Hydronic Heaters: Mysa pairs with self-contained hydronic baseboard heaters.
In-Ceiling Radiant Heating: Ensure the wattage per thermostat does not exceed 16A.

Mysa is not compatible with:

Oil Baseboard Heaters: Not compatible with Mysa due to the specific controls required.
AC Units: Mysa does not control air conditioning systems.

3. Installation Guidelines:

Mysa is designed for circuits up to 16 Amps, optimal on a 20 Amp circuit. Mysa is not suitable for a 30 Amp breaker.
For heaters pre-wired together in a gang box, Mysa can manage them effectively.
If you have only two wires in your gang box, Mysa won’t be compatible. An electrician may provide a solution for heaters with built-in controls.

4. Special Considerations:

Mysa cannot control AC units or support add-ons like relays for multiple circuits.
It's compatible with 208V systems but not suitable for three-phase service requiring a double pole thermostat.
Warning! High Voltage!
Any work with high voltage equipment can be dangerous or even fatal if you do not take proper precautions. You should never work with live wires.
