I have a Fujitsu Air Conditioner. I can set it to heat, cool, dry, fan, and auto. This is a lot newer than the thermostat in my old house, where you had had two switches; one that set it to on, off, or auto, and one that sets it to heat or cool. If it’s on, it’s on and if it’s off, it’s off, I get that. It’s the auto function that’s throwing me off here. On the old AC if you have the temp switch set to cool, the auto function will turn off the AC when the house temp dips 1 degree below the set temp, and when it’s set to heat, it turns off when the house temp rises above the set temp.
With this new thermostat, because it’s the same button that controls cooling, heating, and the auto function (like it can’t be on auto/cool or auto/heat, it’s literally cool, heat, _or_ auto), does that mean that it will try heat the house to maintain the set temperature even in the summer?
Asking because I turn the AC way lower at night so I can sleep, then turn it during the day. I don’t want it to try to heat the house to get it to the higher temp in the morning, I just want it to turn off! The manual doesn’t explain anything and I’m literally having a mental breakdown over this, please help.
In: R2 (Straightforward)
It means that it will either heat or cool, trying to keep the space at the temperature you set. I’m not familiar with your model but maybe you can set a range (that is, cool if it gets above some temperature, and heat if it gets below some temperature).
Surely if you have it on auto it will heat/cool as needed, but when you have it on cool it will cool to the set temperature ?
So put it on cool.
It should be very easy to test exactly what the three settings do. Put it on one of them, adjust the temperature to well above/below the current temperature and see what it does.
(I say well above as devices like this will be designed to avoid repeatedly switching on/off when they are close to the set temperature)
Yep, auto means it will automatically switch between heating and cooling as required to maintain the set temperature.
You generally set one temp for heat and one for cool do when the temp drops below the one temp the heat kicks on and when it gets to warm it goes to cooling. You should be able to go to heat and then cool to set a temp for both to adhere by when your on autoZ if it doesn’t have an app to set it that is. Make sure you set them at least 5+ degrees apart to avoid them fighting!
Auto will either heat or cool to the set temperature depending upon requirements.
Our unit suggests that you choose Heat when it’s cold and Cool when it’s hot. I suspect this is because otherwise you occasionally pay to get rid of heating or cooling you’ve just already paid for.
