Mysa has multiple thermostats designed for different types of heating and cooling systems. To ensure a seamless installation, identify your system type below to find the right Mysa for you.

Mysa for Baseboard Heaters

Designed for high-voltage (120V–240V) electric heating systems.

Compatible with:

• Electric Baseboard Heaters: Standard electric convection heaters.

• Fan-Forced Heaters: In-wall electric heaters with fans.

• Self-Contained Hydronic Baseboards: Electric units filled with oil or water (e.g., Cadet Softheat).

• Radiant Ceiling Heating: Electric radiant cables installed in the ceiling.

Requirements:

• Wiring: Requires a neutral wire (minimum 3-4 wires in the gang box).

• Voltage: 120V or 240V line voltage.

• Load: Max 3,800W @ 240V or 1,900W @ 120V.

• Not Compatible: Low voltage (24V) systems or 2-wire "switch loop" setups.

Mysa for Electric In-Floor Heating

Designed specifically for high-voltage electric floor heating mats and cables.

Compatible with:

• Electric In-Floor Mats: High-voltage heating mats installed under tile, stone, or laminate.

• Electric Heating Cables: Spooled cables embedded in subfloor mortar.

Requirements:

• Sensors: Compatible with most 10kΩ floor sensors (included in box) and legacy sensors (5kΩ–40kΩ).

• Safety: Includes a built-in Class A GFCI for safety in bathrooms and kitchens.

• Not Compatible: Hydronic (water-based) heated floors (use Mysa for Central instead).

Mysa for AC & Mini-Splits

Designed for "ductless" cooling and heating systems that use a handheld remote.

Compatible with:

• Ductless Mini-Split Heat Pumps: Wall-mounted heads.

• Window Air Conditioners: Standard window units with digital controls.

• Portable Air Conditioners: Mobile units with a hose exhaust.

Requirements:

• Remote Type: Your AC must have an existing handheld remote with a display screen (shows temperature, mode, and fan speed).

• Placement: The Mysa unit requires a direct line of sight to your AC unit to send Infrared (IR) signals.

Mysa for Central HVAC

Designed for low-voltage (24V) central forced-air and hydronic systems.

Compatible with:

• Furnaces: Gas, oil, propane, or electric forced-air furnaces.

• Heat Pumps: Central ducted heat pumps (with or without auxiliary heat).

• Boilers: Central hot water boilers connected to radiators.

• Hydronic In-Floor: Water-based radiant floor loops powered by a central boiler.

Requirements:

• Wiring: Requires a standard 24V C-wire (Common wire). If you do not have a C-wire, use the Mysa C-Wire Adapter (included).

Warning! High Voltage!

Working with high-voltage equipment (Baseboard and In-Floor models) can be dangerous or even fatal if you do not take proper precautions. You should never work with live wires. Ensure breakers are turned off at the panel before checking wiring.
