Ecodan Thermistor Specifications


I want to install a therminstor in my Ecodan connecting it to CN20 connector.

I have been looking for the technical specs of such thermistor but I didn’t find anything.

Any idea about the tech specs for the thermistor (TH1)? NTC or PTC? Resistence?

I tried a NTC 10k Ohm but I got a measurement of 5C instead 21C.


Replying to myself…I found the below info in a manual:

Thermistor R0 = 15kΩ ± 3%
B constant = 3480 ± 2%

Can you share a link of such generic cheap thermistor?
