Heater Controller

Here is a very nice thermostatic heater controller.  It features a thermostatic relay made by Johnson Controls (their factory just a few miles from where I live!).  It is intended to control heaters to keep cold blooded reptiles alive.  (A reptile can die if it gets too cold.) My application is keeping all my antiques in the workshop from getting damaged by cold.  I will turn on a small radiator heater set to 600W and a small fan to help circulate the air.  A controller will prevent the heater from running at all on warm days.  (The thermostats on portable heaters are bad about that, they often run just a little even on warm days.)
