Venstar Surveyor Control Wiring

  • Updated

This document is intended as a field reference guide following completion of the Turntide Academy course Control Wiring with Venstar Surveyor Control. This guide should not be construed as a replacement for the course.

Only qualified technicians that are familiar with electrical and mechanical safety procedures should use this guide. The processes outlined here should only be performed with the unit power disconnected.

Step 1 - Power & Communication Verification

  1. Verify the status of the Venstar Surveyor control green POWER LED and amber COMM STATUS LED. The POWER LED should be on. The amber COMM STATUS LED should blink several times followed by steady on, then a brief off period, and repeat.
  2. Document the status BEFORE starting the Turntide Smart Motor System Installation by adding a short video to the Technician App Template you're using for installation.
    1. The video must show the LED sequence and pan to show the control wiring and original induction motor. If the LEDs are not displaying as outlined above, report this issue in a related template from the Turntide Technician App and include a video indicating the LED status. Technicians should not attempt to resolve any pre-existing communication issues.

Step 2 - Remove Wires From Surveyor Control

  1. Remove the wires attached to the G, Y1, Y2, W1, and W2 terminals of the Venstar Surveyor control. Do Not remove any other wiring!
    1. Pro Tip: Take a picture of the wiring before starting. The picture may be a useful resource during step three.

Step 3 - Connect White to Thermostat Wires

Connect the wires of the white TO THERMOSTAT motor controller harness as follows:

  • Green wire to G terminal of Surveyor control
  • Yellow wire to Y1 terminal of Surveyor control
  • Blue wire to Y2 terminal of the Surveyor control
  • White wire to the W1 terminal of the Surveyor control
  • Brown wire of the W2 terminal of the Surveyor control

 

Step 4 - Connect Black To Unit Terminal Board Wires

There are two scenarios for the wiring between the Surveyor control and the unit control. Select the scenario here that matches the unit on which you are working. Follow the directions exactly to avoid any erratic operation issues.

Scenario 1 - Wires Connected to Terminal Strip

In this situation, the wire from the Surveyor control connects to the RTU control terminal strip. Do Not remove any wiring from the RTU control.

Connect the wires of the black TO UNIT TERMINAL BOARD motor controller harness as follows:

  • Green wire to the wire removed from the G terminal of the Surveyor control.
  • Yellow wire to the wire removed from the Y1 terminal of the Surveyor control.
  • Blue wire to the wire removed from the Y2 terminal of the Surveyor control.
  • White wire to the wire removed from the W1 terminal of the Surveyor control.
  • Brown wire of the wire removed from the W2 terminal of the Surveyor control.
  • Red wire to the “R” terminal of the unit control board.
  • Black wire to the “C” terminal of the unit control board.

Scenario 2 - Wires Connected to DDC - Tstat Socket

In this situation, the wires from the Surveyor control connect to the RTU DDC - Tstat socket. Do Not remove or cut any wires leading to the DDC - Tstat socket. When the harness between the Surveyor and DDC - Tstat socket exists only connect the To Unit Terminal Board red and black wire to the RTU control terminals. DO NOT attach the other To Unit Terminal Board wires to the RTU control terminals. Doing so may yield unexpected results.

Connect the wires of the black TO UNIT TERMINAL BOARD motor controller harness as follows:

  • Green wire to the wire removed from the G terminal of the Surveyor control.
  • Yellow wire to the wire removed from the Y1 terminal of the Surveyor control.
  • Blue wire to the wire removed from the Y2 terminal of the Surveyor control.
  • White wire to the wire removed from the W1 terminal of the Surveyor control.
  • Brown wire of the wire removed from the W2 terminal of the Surveyor control.
  • Red wire to the “R” terminal of the unit control board.
  • Black wire to the “C” terminal of the unit control board.

Step 5 - Power & Communication Reverification

One of the last steps following an installation and function testing of the Turntide Smart Motor System is reverifying the Surveyor LED status to control was not impacted by the motor installation. Record another video of the LED sequence for inclusion of in the Technician App Installation template. The video must show the LED sequence and pan to show the Turntide motor installation is complete.

If the LED sequence does not differ from the initial inspection, no action is necessary. If the LED sequence has changed since the initial inspection, contact Turntide Technical Support for assistance (877-776-8470) BEFORE leaving the job site.
