Hi Eric,
I lied to you, the thermistor reads 14.4k @ 3.0 deg C. Was measuring in circuit, took it out of circuit now and that is the reading. My memory is poor but now it is coming back to me. The thermistor value at the target temperature needed to be as close to 15k in order to balance with R1. Apologies for that.
Have finally found the spec https://www.electro-tech-online.com/custompdfs/2009/10/LeadedDisks__B57164__K164.pdf . Mine is the J series which makes it 5% tolerance.
Hope this helps
Thanks
Andrew
