Document No. 540-1031 Installation Instructions October 26, 2016 Wiring Diagram CAUTION NOTE: As a standard grounding procedure, ensure that a ground wire is connected directly from neutral of the 24Vac secondary (the side that connects to the "C" terminal of the TEC) to earth. The installation is complete. The controller’s DOs control 24 Vac loads only. The maximum rating is 12 VA for each DO.
