What do I do if I get an H2 Error Code?
The H2 code means your Mysa did not detect a heater between Mysa Load and L2 (N). The most common resolution to an H2 error is to turn off the breaker and make sure the wires connecting Mysa to your heater are properly secured within each wire nut-as more wires are put in a wire nut, it’s possible for them to lose connection. Once you’ve performed this check, turn your breaker back on to verify that the code has cleared.

What do I do if there’s no heat coming from the heater(s)?
The most common cause for this is an incorrect connection between the heater load wire and the Mysa load wire. Please check that the heater load is securely connected to the Mysa load.

What do l do if the heat won’t shut off?
When the heater does not shut off, this Is often due to a heater wire being connected to the panel L1 (L) supply wire. The panel L1 (L) supply wire (most often a black wire) should be connected to Mysa L1 (L). Please review the wiring and ensure that the heater wires are correctly connected between Mysa Load and Mysa L2 (N). If the heater remains on, please contact our Customer Experience team for further assistance.

What do I do if the thermostat won’t power on?
f the thermostat is not powering on at all, first ensure that there is a green light showing when the faceplate is removed. If the green light is not showing, please review the wiring to ensure that the panel L1 (L) supply wire (most often a black wire) is securely connected to the Mysa L1 (L). Green LED If the green light is showing, the unit is receiving power. Please remove the faceplate for 3-5 minutes and replace it. If the faceplate does not light up, contact our Customer Experience team for resolution of the issue.
