Harman P61 manual turn off in room mode.

Not trying to be a jerk, but depending on what happens before a power outage, you can experience a voltage spike. That voltage spike could take out a board.

I have fairly frequent outages and the lights will sometimes flash on and off several times before going out completely. The voltage spike is likely to occur during the time the lights are flashing on and off.

Only had to change ESP colour to black. Running now and checking temps.

Yes, as mentioned get a surge protector as the disturbance/spike occurs before the power goes out. In fact the power turning back on is planned, and that does not produce a spike. Perhaps the HVAC guys installed a whole home suppressor in your panel? I have one of those, and the P43 plugged into a surge outlet as well. Good luck

is you stove plugged into an actual surge protector? Be careful a lot of power strips are nothing more than an extension cord, meaning no surge protection.

I unplug mine when the power goes out.

Surges happen all the time with the power on - Just a power blip contains power surges - it depends on severity as to whther it will harm anything or not.

A lot of people will buy cheap surge protectors that have the very minimum of joule protection. I get more expensive ones that can handle up to 4,000 joules. They are still cheap protection.

Yes, but in room mode it has some regulation. If your stove is located in the room you want to heat, you would just extend your probe to an inside wall. If your stove is not in the room you want to regulate, ie a door separates the area you want to heat, it won't regulate that other room at all. But at least it's free to try for the room it's in. All you need is two conductor 18 guage wire and some small stab connectors. I cut my wire, but that is because I mounted just the sensor on a wall and used existing thermostat wire. You could use an old type mercury type or a millivolt type also, but it's not the same hookup. They would be wired in series with the probe at the stove.

I haven't pulled the board yet, but would the dip pins in the new one build in 2025, the same as the old one built in 2022. Same version F

Turns out I just had to change the ESP colour to black. I'm up to 4 and no issues.

Are you running the new card? If so, problem might be solved.
