Split Systems Remote Display Retrofit Instructions

  1. Disconnect all power before servicing.
  2. Inspect the parts kit for the following components:
  3. Using a #2 Phillips screwdriver, remove the front grill and unit side panels. On 3000/4000Sh, 6000S, and 8000S models also remove the bottom panel.
  4. Locate the standard temperature controller as shown in the photo below. The sticker on top of the controller designates the terminal numbers 1-5. Mark the wires 1-5 and remove all wires from the quick connect terminals. Locate the green probe terminal block and unplug.
  5. Once the wires are disconnected from the controller, remove the white mounting clips located on the sides of the controller by sliding a small flat head screwdriver under the release tab and slide the white clip off the rear of the controller. Remove the controller from the front of the unit.
  6. Use the black sheet metal remote control cover plate to cover the opening the controller was removed from. The plate should be mounted from the inside. Hold the plate on the outside to mark the mounting hole locations, drill 1/8" dia holes, then secure plate to the inside using the provided black rivets.
  7. Install the power module mounting bracket. Drill 1/8" holes using the Din rail holes as a template and mount in the location shown below.
  8. Install the power module onto the din rail, with end stops positioned to hold secure.
  9. Connect the power module power harness and probe wiring, removing the original wiring as necessary. It may be necessary to remove the fan(s) to access all of the wiring. Use the wiring schematics to map over the wiring to the correct connection points.
  10. Disconnect the remote display head and run the lead wire out through the cover plate hole, securing with the provided cord grip. Reconnect the remote display head lead wires to the power module as follows:
    • (+) to remote display red wire
    • (-) to remote display white wire
  11. Use the provided wire ties to secure all loose wiring.
