Setting HyperStat for Wired Communication & Control

| Overview

The HyperStat can now be wired to an external Modbus client/ BMS/ or the CCU for communication and control, and act as a server to the client in a Modbus-based BMS or an external BMS.

The above capability is provisioned with the introduction of communication options in the HyperStat, and when that configuration is changed in the HyperStat via the communication options, the HyperStat will be able to start communication with the external Modbus client/ BMS/ or the CCU respond to its user intents and sequences.

| Wiring

The wiring that is used to connect a Modbus client/ BMS/ or the CCU to a HyperStat is called the RS485 system & the RS485 Daisy chain Adapter

The RS485 connector uses a three-wire protocol as shown below:

The RS485 Daisy chain Adapter looks like this, as shown below:

Using the above wire combination the wiring of HyperStat to external Modbus client/ BMS/ or the CCU  is achieved.

For more information on how to wire HyperStat in such wired environments, refer Wired Hyperstat

For other factors to be considered while wiring an RS485 cable into a Modbus client kindly refer to Modbus Wring and General Guidelines

| Configuration

To configure a HyperStat to be used with an External Modbus client/ BMS, or the CCU

From the Home screen of the UI 

• Press the + & - buttons together to navigate to other screens of the HyperStat.

The Inputs screen is displayed initially.

• Press the right arrow buttons to navigate to the Comm options screen of the HyperStat.

• Press the down arrow button to navigate to the protocol option.

• Press the right arrow button to access the protocol options.

The default option is the LW MESH for a HyperStat used with the 75F CCU in a wireless mode.

• Press the up arrow button to set the HyperStat, to be used with an External Modbus/ BMS in wired mode.

• Press the deselect button to configure the selection.

• Press the confirm button to confirm the communication option change.

Once the communication option is changed and the configuration options are set, the HyperStat is ready to be used with Modbus Client in a Modbus network-based BMS in a wired mode.

• Navigate to the communication option screen again, to set the required Address, Baud Rate, Parity and Stop Bits.
