Thermostat help?
Question:So I am not to sure how to work the A/C but I set it to 75
degrees on automatic, cool and it came on though it said that it is 71 degrees in this house. I put it above 75 and it goes off. But if I keep it below 75 the A/C goes on and I think it stays on for at least a few hours(i've never heard/felt it cut off). So anyway how would I go about keeping at a constant Temp. 70 degrees on automatic. How do I set it? Am I suppose to set the a/c on what I want the Temp. of the house to be?
Answers:
there should be three parts to your thermostat
auto - on
heat - off - cool
and the temperature setting
auto - on is the FAN control
auto - means that when the heat or cool is ON - it's running
if you are 'at temperature' it's off - with the exception of heat - that runs a little longer until the coils cool down (30-60 secs)
On - runs until you turn it off
heat - off - cool - selects what you want to do -
and 'OFF' with ON just above - means the fan runs without heat or cool being added
temperature - here could be the tricky one -
each thermostat can be adjusted - your setting of 75 - could really mean it's set for 71 - and so you are reading 4 degrees higher than real
so to get it 75 degrees - must be set to 79 - 4 degrees higher
I know this is probably clear as mud - so sleep on it and read it
again, tomorrow - then it might make sense!
best of luck
PS - you may also have a system control option of
Heat - Off - Cool - Auto - on the same switch
setting this to auto - means the system chooses whether to heat or cool (please note - this is different from the FAN auto)
My preference is to TELL IT what it will do - so I choose Heat
or Cool - or leave the silly thing OFF
switch it for a digital one, more accurate.
You might want to have an A/C tech check out your system. From your description, it sounds like your thermostat is not reading correctly. It's a good idea to have your system serviced before the start of the season anyway. It reduces the risk of having it breakdown when you really need it and everybody elses system is breaking down. If your thermostat is faulty, have them install a programmable thermostat to save you the money on your electricity bills that you spent on the service.
The proper settings should be:
auto
cool
and the temp 70
The location of the thermostat is also important. The only part of the house that it cares about is the temp right around the thermostat. So you can set the temp at one temp and it will be much higher or lower in another part of the house.
If you have and old mechanical one, then there is a device on it, called an anticipator. This sets the difference between then the AC or heat will kick on and when it will cut off. For example, the AC will come on at 70 and turn off at 68. This will give you a tolerance of 2 degrees.
If there is still a problem you may want to have it serviced, and checked out. Either that or replace the thermostat. good luck
