Hi Dave
Thank you for replying to this post full E-Nr:HBA13B250B/01.It is capillary type thermostat.I have a little knowledge on oil boilers where you have similar limit/control stats.You would test these with digital heatguns or proprietary tester e.g KBB test unit,neither of which i possess.The stat is working,so I was hoping I could compare my ohms reading against a known parameter.I cannot find such information online.
Thank you again
Angus
