  • Page 27: Connecting Single-Stage Heating Or Cooling Elements

    Heating or cooling elements include equipment such as electric heaters, furnaces, single-speed fans, and curtains. The ratings of the equipment must not exceed the ratings of your PEC Plus’ relays. PEC Plus relay ratings: 10 A at 120/230 VAC, general-purpose (resistive)

  • Page 28: Connecting Curtain Machines

    Curtains are opened and closed to let in more air or less air, the idea being more air cools the building. You can connect up to three curtain machines to your PEC Plus. Each curtain machine you connect requires two relays: one for opening the curtain, and one for closing the curtain. The relays must be side-by-side pairs.

  • Page 29: Connecting Variable-Stage Cooling Elements

    Only permanent split capacitor motors appropriate for variable speed control, or shaded pole motors, can be used on the variable stages. If you are using three-phase power, connect the PEC Plus and the variable cooling equipment to the same phase. For more information, read Using three-phase power on page 20.

  • Page 30: Using Three-Phase Power

    Phason Using three-phase power If you are connecting your PEC Plus to a three-phase system, make sure to connect the control power and the variable cooling equipment to the same phase. Your PEC Plus must be powered from the same phases that supply the equipment. If your PEC Plus power and the variable stages are wired to different phases, the equipment will operate erratically.
