I have a life breath 155max HRV that is no longer working.
When I purchased the home it worked just fine. Each bathroom in the house has the switches on the wall to turn the unit on but when they are pressed it does not turn on.
I'm not sure when it stopped working.
I installed a programmable thermostat a few months ago(Honeywell RTH7600). I'm not sure if this was when it stopped working or if it has anything to do with it. That is the only change that I have made to the heating or cooling system in the home.
Will a programmable thermostat cause the HRV to stop working?
