I could use another set of eyes on this. I recently installed a thermostat in my wife’s office (converted house). The AC system is less than a year old (heat pump) but admittedly in Orlando we don’t have to run heat often. With the cold snap I noticed the office wasn’t heating up quickly. I know there have been a bunch of issues with Emergency Heat so I figured this might be what I was seeing, however I opened the cover and noticed it doesn’t look like there is anything connecting to the W2 terminals from the thermostat however there is definitely a cable coming off the board.
My HVAC knowledge is limited so am I looking at this correctly? It looks to me like I should probably run a W2 cable to engage the electric heater. Thoughts?
