Hi there,
I need to change the thermostat for an second story heat pump. I will change it out for a setback/auto changeover. I was looking at the 3/2 stage Honeywell visionPro model and noticed it had the ability to interface with a remote indoor sensor. Where the t'stat is mounted now, the majority of the space stays pretty comfortable, but two back bedrooms stay 5-6 degrees colder than the rest of the cooled/heated space. Do you have any idea if the remote temp sensor might balance the temp better? I may just need to move the t'stat location, it is at the top of an open staircase from the kitchen area, I suspect the heat from downstairs/kitchen may be fooling the upstairs thermostat somewhat. I'm no longer in the trade, but ran commercial refrigeration for 10 years. Thanks for the advice.
