I have a customer with an old unidentifiable program clock that basically kills pneumatics on one output and kills a DX unit on another. It has three inputs. Indoor and outdoor temp switches w/ basic open/closed contacts and a mystery "outdoor heater" connection. Hopefully the picture shows up, but what in the hell would that be???
I'm thinking about using a Crouzet Millenium 3 controller (model CD 12 to be exact). I really haven't been able to find a simple program clock that has inputs. Any ideas?
