Standalone HyperStat Split 4 Pipe Unit Ventilator + Economizer

5 Minute Read

| Overview

The HyperStat Split 4-Pipe Unit Ventilator profile extends 75F’s smart control capabilities to legacy unit ventilators, enabling intelligent, independent operation without requiring a connection to the Central Control Unit (CCU). In standalone mode, you configure the profile directly on the device, and control algorithms run locally to manage the connected unit ventilator based on configured parameters and available sensor inputs. For more information on the device and its components, refer to HyperStat Overview and Installation

The solution supports flexible equipment configurations, including fan speed control, heating and cooling water valve control, auxiliary heating, damper operation, and other supported control functions. Built-in standalone scheduling enables equipment operation based on configured occupancy schedules, while standalone algorithm tuners let you adjust control parameters to suit equipment requirements and operating conditions.

By combining local algorithm execution, configurable equipment control, scheduling, and tuning capabilities, the standalone profile provides an independent solution for managing unit ventilator operation, improving occupant comfort and supporting energy-efficient HVAC performance without relying on CCU connectivity.

The HyperStat Split supports the following standalone applications.

• 2 Pipe Unit Ventilator
• 4 Pipe Unit Ventilator
