Control Wiring Training Test Stand for NMD Service Teams

IMG_1057

To further the HVAC service abilities of our staff, we have constructed a test stand for training in control wiring.  We have thermostats, zone panels, zone valves, relays, contactors, and terminal blocks mounted on a plywood board which we can use to simulate a live system.  This permits our team members to study how controls affect the operation of heating, cooling, and ventilation equipment.   Here we see Dan, Tom, Nate, and Mariah installing some wiring to test the operation of the control board.
