Automatic Inline Thermostat Extension Cable

I became concerned when one of the automatic inline thermostats failed to work. However after puting it in the freezer for 3 hours as instructed I am happy to report that the thermostat was shocked and began to function again. This instruction should be listed as a trouble shooting instruction.

Works great. Been using HT for years and continue building our system.

Saves money and easy set up. Just plug in.
