My fiance as well as I have this continuing discussion at certain times of the year….basically Spring as well as fall. I am warmer natured than she is as well as I care about the condo cool….she does not. Her perfect temperature to have the Air Conditioner as well as Heater plan set at is about 69 degrees, mine is 75 degrees. There are times our A/C should be working when she has the heating system set as well as running. I have even had to chop down as well as run a fan facing my side of the bed at certain times to keep some cooler air blowing while she runs the Heater as well as Air Conditioner device on warm; Fortunately, the two of us have a newer Heating in addition to A/C device in our beach condo so our electric bills are not real expensive even with the varying uneven temperatures. It can be quite discouraging at times when I am doing housework yet she wants the temperature set at 69 degrees. It is easy to chop into a sweat when doing housework. Finally, I found the answer as well as I contacted the local Heating in addition to A/C supplier to inquire about the programmable control unit. After talking to a worker I discovered that was the exact thing the two of us needed! By having this type of control device I am able to set the rooms to varying temperature so our family room, where she spends a lot of time, can be set on 69 degrees as well as the family room, where I spend most of my time, can be set on 75 degrees. Every one of us are both ecstatic now with the temperature of our home. Finally peace in our beach condo regarding the comfort of both of us.
