I have been having an issue with my TTIfab Stratos heat pump heater. I noticed the heater was on, even though no one turned it on. I turned off the heater on the control pad. The next day when I took a look, the heater was back on. I don’t know what the issue is. We have had a few power outages lately, does the heater automatically turn itself on after a power outage? I can’t seem to turn it off and have it stay off. Any ideas?
