Our system senses when to turn off to cool the room, but does not sense when to turn off
Our system recognizes when the room gets too hot (within a couple of degrees) and it starts to cool our baby's room, however it doesn't sense when to shut OFF the air conditioner and it gets way too cold in her room.....do you think we have something wrong with the settings? We have it on AUTO - the other options instead of AUTO are Max, Min please HELP this is difficult trying to climate control her room for healthy sleeping. Thank YOU.

Indoor sensor to sense the room temp and must cut off the compressor by working. If sensor defective, compressor will continuously running resulting to over cool in room. And also 23 C degree setting temp is best cooling for office and bed rooms. If for peculiar instrument which should be kept under low temp, can be set as mentioned temp (say 18 C or 16 C )<br />
Comonly that is because the condenser sense is not conected or faulty, but check also the room temp sense as the solder in the conector in the main board. (condenser sense is metal case, and room sense is plastic cover).
Check the thermostat setting...in the auto machines, with a reversing valve, there is no heating or cooling, generally, in the sensing temperature band of 19 Deg C to 22 Deg C and it only works on blower mode, re-circulating the room air. When the sensing temperature goes below 17 deg C, it works on heating and when the sensing temperature goes above 24 deg C, it works on cooling
Sounds like the compressor may be overheating. You need to check the outdoor condenser coil it may be stopped up with dirt, in turn, overheating the compressor. The condenser coil looks like a radiator and the outdoor fan blows through it, in a sense releasing the hot air from the building. If the coil is stopped up, it can not release the heat. You can wash this coil out with a hose and sprayer. Just be careful not to get the motor wet and be sure to shut off power.
Here's the deal: If your Vitodens 100 has outdoor temperature sensing capability, either built in or via external aftermarket control such as Tekmar or other, and the temperature outside is above warm weather shut down (WWSD), then the boiler will not operate for space heating, but will operate to make Domestic Hot Water (DHW) only. Generally speaking WWSD is facoty set at 20*C, since this is normal room temperature so the boiler will not need to operate at temperatures above this number as it is warm enough outdoors to heat the house to comfortable levels.
If your Vitodens 100 does not have outdoor temperature sensing capability then you should check to see if your room thermostats are operational and calling for heat since the boiler is only responding to this on-off control based on room temperature. (turn up your room thermostats)
In both cases you need to make sure that your heating system's distribution pump and zone valves are operating correctly.
In any case you should be calling a heating contractor if you suspect that there is a problem with your boiler and/or heating system.
Behind the filter there should be a small metal tube that senses the temp. entering the unit sometime this is too close to the metal fins and sense the cold from the fins and not the air coming in. Make sure this is away from the fins and try a different temp. setting.And relocating the unit. These units tend to give off more heat that cooling because the hot air is returned to the inside of the room and not vented outside like window units.This is an EdgeStar 12,000 BTU unit, correct?
HELLO ... THERE IS A THERMOSTAT SENSING BULB THAT MAYBE OUT OF PLACE OR TOUCHING THE COIL. ALSO MAKE SURE YOUR CURTAINS ARE CLEAR FROM YOUR UNIT BY AT LEAST 3".
IF YOU CAN SEE THE REMOTE SENSING BULB OR ALUMINUM LINE, WARM IT UP WITH YOUR HAND AND SEE IF YOUR UNIT CONTINUES TO CYCLE OFF. IF IT DOES CHANCES ARE YOUR THERMOSTAT IS BAD. IT IS NOT EXPENSIXE ... UNDER $30.
