| Overview

HyperStat Split is the best-in-class thermostat that can measure parameters in the zone and controls equipment at zone and system levels (RTUs & FCUs) by connecting seamlessly over two wires reducing the cost of additional cabling.

The Hyper Split and its Interface are decoupled, all the loads' controls are moved near the load, and only Indoor Air quality is measured in the zones.

HyperStat Split can either be connected and controlled by a CCU wirelessly or it can work in the stand-alone mode.

It also has a fail-safe mode when connected to the CCU when there is a drop in communication.

| How it Works.

HyperStat Split has 2 parts,

HyperLite sits and monitors Air quality (with up to 8 onboard sensors) inside a zone and is equipped with a 2.8" TFT screen paired with mechanical buttons and a touch slider for taking user inputs and displaying zone data.

Connect Module sits inside the RTU/FCU, does stage or modular controls, and can accept up to 8 Universal analog inputs.

| Wiring

Connect Module is Powered by commonly run 24V AC or DC and is equipped with Universal analog inputs for interfacing with 3rd party equipment/sensors. It has both relays as well as 0-10V/4-20mA Analog outputs to control both staging and modulating load.

The following is a sample wiring illustrated for a HyperStat Split.


The wiring for the communication and power to the HyperLite is connected to POR A, and B of Connect Module to Normal A & B of Lite. 

The Table below provides more information on the wiring of the Hyperstat Split.

Supported wire length

200 ft.

Supported cable type The 18/2 Thermostat wire, does not support installations of multiple HS Splits on 18/4,18/6, or any higher core count wires
Wiring to be laid In seperate Conduits and not along with power-carrying wires. Plastic conduits are preferred.
Precaution connect POR A of the connect module to A of the Lite, and POR B of the connect module to B of the Lite, and not otherwise.
Power Source The power source must be 24V AC only.

The Connect Module further features an additional OWI interface to connect 75F OWI-compatible sensors.

Jumpers 1:

At this position, a jumper is used to short the RH and RC to enable and power both the cooling and heating stage relays for use.

When the jumper is not connected, the heating and cooling relays are independently powered via the RC and RHconnector terminals.

Jumper 2:

The Rext1 jumper in this position is used to toggle between the 24V or dry, potential free contact to the exhaust fan relays.

When used, it provides 24V; when not, it provides dry contact/ potential free contact.

Also, there is a Rext2 which is always Dry contact, when required to provide a 24V to the contact, a wire needs to be shorted between Rext1 and Rext2 externally on terminal blocks.

Jumpers 3:

In this position,

Short if the HyperStat Split device is the last device on the RS485 line.  

If it is not shorted, there is no terminal resistance, and the device can be used as one of the multi-drop connections.

Another jumper is used for terminal resistor isolation in Power over RS485.

This jumper must always be on as any node connected in a POR communication should have a termination resistor.

| Mounting

Mounting HyperLite

  • Mount the HyperLite back (Subbase).
  • Level the HyperLite in the desired mounting location.
  • Mark the holes on each side.
  • Drill a 5/16” hole.
  • Insert the provided anchors.
  • Screw the sub-base into place using the provided #6-32 1” screws
  • Place the HyperStat Interface-HyperLite PCB and the back plate (only if the gang box is fixed vertically) on the gang box such that the back plate covers the gang box and fix these two items to the wall gang box with the PHP screws provided in the box.
  • Now align the HyperStat main to lock onto the HyperStat Interface- HyperLite PCB.
  • Use the Allen head screws to make this entire setup tamper-proof.
  • Rubber covers 1 and 2 must be fixed to cover the programming pins.

Mounting Connect Module

  • Install the Connect Module on a DIN rail, as below.


  • Use the screws provided to the back of the Connect Module, to lock the DIN clip to the Connect Module.
    Note: The DIN clip is spring-loaded and would snap on the DIN rail. To fix it to the wall bracket, use the screws provided.
Part Number Part Description
1 Connect Module
2 DIN Clip
3 Screws
4 DIN Rail


  • Install the Connect Module directly on a wall, as shown below.


The Hyper Split and its Interface are decoupled, all the loads' controls are moved near the load, and only Indoor Air quality is measured in the zones.

For Pairing, Configuration, and Configuration Parameters refer to HyperStat Split- CPU & Economizer Profile
