Fermentation chiller thermostat help

[yusupov]

The thermostat (ritetemp 6020) on my fermentation chiller broke. I had the thermistor extended so it was reading the temp on the inside with the controls on the outside.

I cant find a ritetemp 6020 anywhere, what other thermostats can i buy instead (make + model) that will allow me to do the same thing with the remote thermistor?

Thanks!
