| Overview

The HyperStat is part of 75F's vertically integrated suite of intelligent building solutions, delivering multi-mode sensing, remote monitoring and individual zone control for comfort and productivity of building occupants, for more information on refer to HyperStat Installation Hyperstat UI.

With the vision towards platform play and greater interoperability in the building management space, the HyperStat is built and developed in such a way that it can either, work in a 75F BMS environment connected to 75F's CCU configured for system and terminal level profiles, or it can support an external BACnet server as a BACnet client. It can also work as an independent or standalone device which can work as per profiles which can be configured in the Hyperstat itself.

The Hyperstat as BACnet client feature provides the capability to the customer, to configure a Hyperstat in a BACnet server and read the data from in a certain format, with its powerful onboard sensors. HyperStat can be an excellent asset to the BACnet server supported BMS.

| Wiring

Below is the wiring schematic followed when HyperStat is used a client in a BACnet server

| Wiring Harness

The 75F supports a type of wiring harness to meet the need to Daisy Chain Hyperstat in a BACnet network.

4 Pin to 6 Wire Screw Connector

  • Relay1: Y1
  • Relay2: Y2
  • Relay1: G
  • Relay1: W1
  • Relay1: W2
  • Relay1: O/B
  • RS485 Wiring: 
    • Yellow Lever: A+
    • White Lever: A-
    • Black Lever: S

Note: If HyperStat is not the end of the RS485 network bus (EOL), remove the TER ISO Jumper, and if the end of the RS485 network bus (EOL) do not remove the TER ISO Jumper.

Post wiring once the device is powered on, you configure HyperStat to act as a BACnet client.
