I am considering changing my solar thermal controller. The existing controller uses a Pt1000 sensor in a roof mounted solar collector. My preferred choice of replacement expects input from an NTC 20 kΩ sensor. Can anyone suggest an affordable converter?
It would probably be possible to produce something using a PT1000 RTD Temperature Sensor Amplifier, DS3502 I2C Digital 10K Potentiometer and a Raspberry Pi Peco or similar if I possessed the necessary making skills.
However, I would prefer a ready made device that wouldn’t frighten a heating installer!
Any suggestions?
