Great, then you can answer my very simple question!
These are made to have 2 independent probes so you can control 2 racks off the same thermostat. When you purchased the Herpstat 2 direct from SpyderRobotics... did the 2nd probe come with the thermostat or do you have to purchase it separately? I cannot find any of this info on their website and have a feeling I'll get a faster response from you guys.
Thanks!
