| How it Works
The ClimaVision HyperStat Split Conventional Package Unit & Economizer profile is a standalone profile, that provides heating, cooling, and Economizer equipment controls for conditioning.
HyperStat split is a combination of HyperLite and the Connect Module.
The HyperLite module is mounted inside the room providing the room Temperature, Humidity & IAQ sensing.
The Connect module is mounted on the RTU or FCU, to provide the necessary conditioning based on the temperature and IAQ sensed.
For more information on the HyperStat Split device and its mounting refer to HyperStat Split Overview & Installation.
It provides the flexibility to choose between fully modulating and staged equipment control. Possible equipment configurations include:
- 3 Stages of cooling equipment control
- 3 Stages of heating equipment control
- 3 Stages of fan speed control
- equipment control
- Fan Enabled and Occupied Enable control
- Humidifier and Dehumidifier control
- 2 Stages of Exhaust fan control
- Modulating Cooling, Heating, OAO Damper & Linear and Staged Fans for cooling and heating as Analog Outs
- Sensor Bus Inputs to accommodate up to 4 types of daisy-chained sensors
- 8 Digital/Analog/Thermistor-based Universal Inputs to accommodate varied forms of input as provided below in the Configuration parameters section table.
| Wiring
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, 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 separate 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.

Test Signal
This is used for troubleshooting and testing the equipment if the configuration and the field setup are in sync, and the device is communicating properly with the controlled equipment. Also at any point, you can override the value of the output the algorithm decides.
We can use the test signal for relays to turn them on or for analog out to ramp up and see if the equipment works according to commands from the device.
Test Signal Time Out
once enabled it will be active for an hour if the screen is not changed, after an hour of no interaction on the screen. zone screen displays and the test signal will be OFF.
If the screen changes from the test signal configuration screen it will be timed out in one minute (time for the algorithm to run next).
Note: The test signal for modulating output is in deci volts ranging from 0.0dV to 100.0dV.
| Operation of Staged Fan Speed Control at Analog out2
The above options will appear based on the number of heating and cooling stages associated with the relays and if there are no heating/cooling stages then the staged fan cannot be associated with the AOs.
This means the user can now decide at exactly what speed the VFD, or analog fan should function when the cooling or heating stages are triggered, which effectively takes care of any kind of disproportionate operation between the cooling/heating stages and the analog fan.
This means now the analog fan operates at least at 75-80% of its maximum speed when the cooling/heating stage 1 is triggered.
Also, when the no cooling or heating stages are triggered due to zero loop output, we can have a small amount of fan loop output, that could provide a small percentage of fan speed, managed by altering the Analog Fan speed multiplier, and tuner parameter.

| Multi-Module Criteria & Nuances
Like the other devices & profiles under the ClimaVision system, the HyperStat Split and the CPU+Economizer profile also support the multi-module concept.
Below are the few criteria set and nuances followed during such multi-module configuration in a zone for a site.
- Only up to three HyperStat Split device / CPU+Economizer profiles can be paired within a zone.
-
At any time in a multi-module zone, all the modules within the zone will have the same schedule state, and the same is indicated on the zone level.
In CCU
In Portals
-
Any external schedule influencers once triggered will influence the entire zone, irrespective of whether the other modules are enabled via configuration for that state.
-
Once the schedule state is consumed by the zone from the module of the highest rank in the multimodule, then the desired temperatures are inherited by other modules in the multimodule zone.
For more information refer to Effects of Schedule States in the Building
| Post Configuration
The zone paired with CPU & Economizer profile is displayed in the CCU as below.
You can see widgets configured in the heatmap pages in the portals as below:
The widgets with the OAO details in the portal are visualized as below.
| Modes & Operations
As in the other HyperStat profiles, the CPU & economizer profile of HyperStat split as well supports the following fan and conditioning modes.
Fan Modes
- Off
- Auto
- Fan Low Current Occupied Period
- Fan Low Occupied Period
- Fan Low All Times
- Fan Medium Current Occupied Period
- Fan Medium Occupied Period
- Fan Medium All Times
- Fan High Current Occupied Period
- Fan High Occupied Period
- Fan High All Time
Based on the fan stages configured in the configuration window, the fan stages are made available in CCU and the portal for selection as user intents.
Note: The HyperStat Split hardware supports only the following fan modes at its end,
And when a change is made, it would translate to the following in the CCU.
- Auto------ Auto
- Low------Fan Low Current Occupied Period
- Medium-------Fan Medium Current Occupied Period
- High-------Fan High Current Occupied Period
Conditioning Modes
- Off
- Auto
- Cool Only
- Heat Only
| Controls and Triggers Strategy
| Controls | Trigger Strategy |
| Cooling Stages | Cooling stages trigger when the zone demands cooling, based on the current temperature. The cooling stages switch ON based on the cooling loop output, whose values are scaled for the different stages. And switches off based on conditioned current temperature values. |
| Heating Stages |
Heating stages trigger when the zone demands to heat, based on the current temperature. The heating stages switch ON based on the heating loop output, whose values are scaled for the different stages. And switches off based on conditioned current temperature values. |
| Fan Stages |
Fan stages trigger based on the fan loop output which is a result of cooling loop and heating loop outputs, during cooling and heating operation respectively. Fan control configured as modulating using analog out the percentages for the low, medium, and high are altered to 30% 60%, and 100% respectively. |
| Fan Enable |
Fan enable is a provision introduced to enable additional fan control, which switches "ON" during the occupied schedule, and when any conditioning is happening during the unoccupied schedule. Example:
Note: Fan Enabled is not a control option for the Fan stages. the fan stages control needs to be mapped separately for the system to start conditioning. |
| Occupied Enable | A relay mapped to Occupied Enable is "ON" whenever the zone is in an occupied schedule and "OFF" when any conditioning happens during an unoccupied schedule. |
| Humidifier |
A Relay mapped to the humidifier is turned on whenever the humidity level for the CPU drops below the target Minimum Inside Humidity, a tuner value. And shows the user a target humidity control in Zone Screen on CCU and Facilisight portal |
| De Humidifier |
A Relay mapped to the dehumidifier is turned on whenever the humidity level for the CPU goes above the target Minimum Inside Humidity, a tuner value. And shows the user a target humidity control in Zone Screen on CCU and Facilisight portal |
| Exhaust Fan Stages |
Exhaust stages trigger based on the economizing loop output. Stage 1 triggers when the economizing loop output is at 50% (Default). Stage 2 triggers when the economizing loop is at 90% (Default). The exhaust threshold percentage for the economizing loop can be defined during the configuration using the Exhaust Fan Stage 1(Threshold) and Exhaust Fan Stage 2 (Threshold). There is a hysteresis associated with it to prevent short cycling of the equipment, which can be defined using the parameter Exhaust Fan Hysteresis (%) during configuration. Example: For default hysteresis of 5% the Exhaust Fan stage 2 deactivates at 90-5 = 85% of the Economizing loop output. And Exhaust Fan stage 1 deactivates at 50-5 = 45% of the Economizing loop output |
| OAO Control
Outside Air Optimization (OAO) as we know is bringing in the outside air into the room space when conditions are favorable for free cooling.
The OAO control trigger with the CPU & Economizer is driven by the outsideAirFinalLoopOutput
The factors contributing to the outsideAirFinalLoopOutput vary based on the parameters configured during the profile configuration.
The table below talks about the possible scenarios, and the respective contributing factors for the outsideAirFinalLoopOutput.
| Scenarios | Favorable / Unfavorable Conditions | Contributor for the Final Loop output |
|
The system uses just the Outside & Inside Air Temperature & Humidity |
If the Outside Air Temperature is < standaloneEconomizingDryBulbThreshold (an OAO tuner parameter = 55°F) |
Then, outsideAirFinalLoopOutput= OutsideAirLoopOutput= economizingLoopOutput (which uses the outside air temperature sensed and the 55°F for the error calculation of the loop) |
|
Else If the Outside Air Temperature is slightly > standaloneEconomizingDryBulbThreshold (an OAO tuner parameter = 55°F), Then, the system would look for the following And, If Outside Enthalpy (product of Outside Air temperature and humidity)+standaloneEnthalpyDuctCompensationOffset (Tuner parameter, which is by default 0) < Inside Enthalpy (product of Inside Air temperature and humidity) |
Then, outsideAirFinalLoopOutput= OutsideAirLoopOutput= economizingLoopOutput (which uses the outside Enthalpy and Inside Enthalpy for the error calculation of the loop) | |
| If the Outside Air temperature is not within the Tuner parameters, standaloneEconomizingMinTemperature (0°F) & standaloneEconomizingMaxTemperature (70°F) | Then, outsideAirFinalLoopOutput= OutsideAirLoopOutput= 0 as there will be no economizingLoopOutput | |
| And If the Outside Air temperature is not within the Tuner parameters, standaloneEconomizingMinHumidity (0%) & standaloneEconomizingMaxHumidity (100%) | Then, outsideAirFinalLoopOutput= OutsideAirLoopOutput= 0 as there will be no economizingLoopOutput | |
| The system uses Outside, and inside Air Temperature and humidity along with the CO2 Threshold (If configured) |
Then when Zone CO2 (A sensed parameter) > Zone CO2 Threshold (A configuration parameter), the Demand Control Ventilation loop kicks in. DCVLoopOutput= (Zone CO2- Zone CO2 Threshold)/zoneCO2DamperOpeningRate (A configuration parameter) |
Then, outsideAirFinalLoopOutput= OutsideAirLoopOutput= economizingLoopOutput, DCVLoopOutput or outsideDamperMinOpen (a configuration parameter) whichever is greatest among the three is considered |
|
The system uses Outside, and inside Air Temperature and humidity, with the CO2 Threshold & the Mixed Air Temperature MAT (If configured) |
If Mixed Air Temperature is Between the Tuner parameters standaloneOutsideDamperMixedAirTarget (50°F) & standaloneEconomizingMaxTemperature (70°F) |
Then, outsideAirFinalLoopOutput= OutsideAirLoopOutput= economizingLoopOutput, DCVLoopOutput or outsideDamperMinOpen (a configuration parameter) whichever is greatest among the three is considered |
|
If Mixed Air Temperature is > Tuner parameter standaloneEconomizingMaxTemperature (70°F) or Mixed Air Temperature is < Tuner parameter standaloneOutsideDamperMixedAirMinimum (44°F) |
Then, the OAO damper position moves towards the minimum position. | |
|
If Mixed Air Temperature is Between the Tuner parameters standaloneOutsideDamperMixedAirMinimum (44°F) & standaloneOutsideDamperMixedAirTarget (50°F) |
Then, outsideAirFinalLoopOutput= OutsideAirLoopOutput* Where, OutsideAirLoopOutput= economizingLoopOutput, DCVLoopOutput or outsideDamperMinOpen (a configuration parameter) whichever is greatest among the three is considered |
| OAO Tuners
- standaloneEconomizingDryBulbThreshold = 55°F
- standaloneEconomizingMinTemperature= 0°F
- standaloneEconomizingMaxTemperature= 70°F
- standaloneEconomizingMinHumidity= 0 %
- standaloneEconomizingMaxHumidity= 100%
- standaloneOutsideDamperMixedAirMinimum= 44°F
- standaloneOutsideDamperMixedAirTarget= 50F
- standaloneEnthalpyDuctCompensationOffset= 0°F
- standaloneDuctTemperatureOffset= 0°F
