I have lost three omnistat thermostats to electrical surges now. All three times the communications ability was damaged and one will not even power up. These events are usually a lighting strike in the area. AC surrge protectors and gfi outlets have protected other electronic equipment.
I am thinking the surge is coming in via the heat pump control wiring. I also have a leviton whole house surge protector.
Has anyone successfully put surge suppression on heat pump control wiring?
What did you use?
Thanks.
