Temp Sensor split environment Philco F / C model PHS25HA4BNI

Good day. I ask you this question to get out of doubt. A few days ago we installed this air, cold / heat of 2200F, which has as is known the temp sensor. environment close to the evaporator coil. Operation is acceptable and there are no inconveniences.
What I have observed is that the sensor bulb is covered with the lining / spaghetti, that is to say that the sensor bulb is not exposed but that it is "covered" for that reason, at least 1cm. I do not know if that is ok but I have noticed that having an ambient temperature of ~ 24 ° C, measured with a digital tester, the air does not cut, it still works. Is it because the sensor is covered ???
I attached a photo of it for your understanding.
Thank you.

Hello, some models come, there may be a difference between the sensor and the thermometer of 1 or 2 degrees, if there is much more to worry about.

Sometimes on some platelets it takes time to feel the temperature and give the order from the platelet to the compressor relay. Try to a degree waiting a few minutes between cutting and starting.

Hi triatlon99, I commented that I was 1 hour approx. with the split at 24 ° C and I started to raise the temperature to 1 degree, waiting a while between each degree, and cut off the compressor when I reached 27 ° C.
I had no opportunity to measure the TA with the tester at that time ...
It seems to me that I will cut the lining that covers the sensor bulb and see if it has greater sensitivity ...
Greetings.

Hello triatlon99, I tell you what I did: I discovered the bulb of the split room temperature sensor, before lighting it I measure with the tester where the air enters and it marked 24 ° C.
Then I turn on the device at 24 ° C and only pull air, the compressor does not start. It starts after a while and when I place it at 25 ° C it stops. That was just the problem.
I thank you and appreciate the response
regards

Hi Sam1963, depending on the manufacturer, the sensor may be covered or not, that is not relevant, if the equipment works normally, you should not worry about the temperature, unless it stops cooling, otherwise you should take into account , the position from which you do the temperature test in the room, standing in front of the air flow of the equipment for example, will always report a much lower temperature than the one actually detected by the temperature sensor, from your position, so this taking the temperature readings inside a room, is very relative. That is, the most correct place for the test and where to locate the sensor or thermometer probe would be, for example, approximately at the same air inlet to the evaporator of the indoor unit itself or just from the position where the ambient temperature sensor is located of the device, without making contact with the surface and never facing it. In most Split models, the air intake would be from the top of the indoor unit itself, from that position the actual air temperature inside the room can be taken. Good luck and happy holidays.

Hi friovega63, thanks for answering, in principle I must say that the measurement of temp. I made the environment where the air enters the evaporator, that is, from the top. As I was saying to the triathlon friend99, I only cut the compressor when the temp went up. from remote at 29 ° C ...
If necessary, does anyone know the correct value of this sensor?
Greetings.

I don't think it's the devalued sensor but most of the well-known Philco sensors have a value of 10 kilo ohm, but there are also models with the 5 kilo ohm sensors. The sensors should measure them with the multimeter placed on the 20 kilo ohm scale, at a constant temperature of +25 degrees Celsius. To emulate this temperature, you can mix hot and cold water inside a container, helped by a thermometer. It is good to submerge the tip of the sensors into the water, for about 3 minutes before proceeding to measure, to obtain a more accurate reading. S @ lu2

In particular, I would not do it, because it can be worse, besides you do not have calibration or certification in an instrumentation laboratory that thermometer that you use to make the measurements, so you would not know for sure which of the two sensors tells the truth . Perhaps it does get another reliable thermometer and it tests the same reading, in that case it is better to replace the probe. S @ lu2

I think it is the best and prudent option to take, if in general the team works well, instead I did not judge it more. S @ lu2

I agree on that point with you, if you really have the way to ensure that your equipment, makes the stops bad, I repeat that you must have a certified thermometer and otherwise you should try one more to support the reading of the other from the same position. S @ lu2
