Variable Volume Control
Uses both heat and optic sensors to monitor cooking activity and modulate airflow. Factory-installed optic sensors enhance control in high-steam, low-temperature environments.
The microprocessor controls all unit functions and is factory-programmed, wired, and tested per job configuration. Supports standalone operation or BMS integration via BACnet (MS/TP or IP) and Modbus (RTU or IP).
Standalone furnace controller with keypad/LCD for setpoints and lockouts. Guided startup, alarm monitoring with fault logging (time/date/temps/status), plus dedicated remote alarm output.
Constant Volume Control
Ensure code-compliant safety with automatic backup controls that activate exhaust when cooking heat is detected and keep fans running until temperatures drop. System overrides manual controls and links all fans within the same zone.
Variable Volume Control
Industry-leading turndown, high-efficiency motors, and responsive heat sensors drive energy savings with demand-controlled kitchen ventilation. Monitors cooking temperature and modulates exhaust and supply fan speeds, reducing airflow and energy use during lower cooking loads.
Enables third-party control of packaged DX, heat pump, or indirect gas heat systems while maintaining built-in refrigeration and heating safeties.
Constant Volume Control
Centralizes control with clearly labeled connections and factory prewiring to minimize field wiring for power, fans, and lighting. This reduces installation time, coordination issues, and wiring errors that can delay inspections.
Factory-programmed, wired, and tested microprocessor controller. Operates standalone or through BMS (BACnet or Modbus, MS/TP or IP), optimizing temperature control for safe, energy-efficient performance.
The 4-speed analog control offers simple, cost-effective operation of a single HVLS fan. Designed for a standard 2x4 junction box, it features preset speeds (25%, 50%, 75%, 100%) and Forward/Off/Reverse control in a clean, surface-mounted design.
Premium BACnet touchscreen control for HVLS systems with intuitive LCD interface. Control up to 20 fans (grouped or independent), with scheduling, diagnostics, password protection, and BMS integration. Optional temp/humidity sensors enable automatic operation.
The multi-speed analog control delivers precise 0–10V variable-speed operation for a single HVLS fan. Designed for a standard 2x4 junction box, it includes Forward/Off/Reverse control and provides smooth, flexible airflow adjustment in a clean, surface-mounted design.
The standard touchscreen provides cost-effective HVLS control with an intuitive LCD in a 2x4 wall-mount design. Operate up to 3, 5, or 10 mixed-model fans with password protection and built-in diagnostics for simplified troubleshooting.
The optional remote interface eliminates the need for physical access to the unit-mounted microprocessor, allowing users to view and adjust control parameters remotely. Available with the microprocessor or network interface.
Optional remote panel simplifies wiring with matching terminals and built-in fan, heat, and cooling enable switches. Optional status/alarm lights. Available in NEMA 1, 2, 3, 3R, 4, 4X, and 12 enclosures.
Provides intuitive LCD control with heating and cooling directly from the space. Features include fan enable/disable, setpoint adjustment, password protection, and BACnet MS/TP BMS integration for flexible, convenient operation.
Factory-programmed microprocessor with proven control sequences. Each unit is wired and fully tested prior to shipment. Supports standalone operation or BMS integration via BACnet or Modbus, ensuring safe, efficient performance.
Stand-alone VFD
Factory-supplied standalone VFDs are sized and programmed to the motor and fan’s maximum speed. The BMS provides the control signal and manages fan speed, isolation dampers, and bypass dampers.
Constant Pressure control monitors static or velocity pressure and automatically adjusts fan speed to maintain setpoints (including constant CFM). By modulating speed, it reduces fan energy use and minimizes conditioned air exhaust.
The Vari-Green HOA provides hand/off/auto control with easy BMS integration. In Hand mode, set fan speed locally; Off stops the fan; Auto enables remote control. Two Auto options allow remote on/off with preset speed or remote on with 0–10V speed signal. Includes 24V power for auxiliary controls.
IAQ temperature/humidity control monitors space conditions and automatically modulates fan speed to maintain setpoints by adjusting ventilation rates.
IAQ VOC control monitors volatile organic compound levels and automatically modulates fan speed to maintain proper ventilation. By ventilating based on VOC concentration, it prevents over- or under-ventilation and responds to up to 10,000 VOCs.
Remote dial or touch control enables manual fan speed adjustment from a wall-mounted 2x4 box with cover plate. Includes 24VDC transformer. Touch Remote features a 10, 30, 60, or 90-minute auto-off timer.
Steps line voltage down to 24V to power the motor and controls. It includes one NO and one NC dry auxiliary contact for damper control or equipment interlock.
Two-speed control allows the motor to operate at preset speeds A or B. Speed selection via SPDT switch/relay (dry contact) or 115–230VAC wet input. Includes 24VDC transformer; accepts 115/208–240V input.
Pre-engineered, Stand-alone Controller for Laboratory Exhaust Fans
Pre-engineered, standalone controller for laboratory exhaust systems, integrating Vektor fans into variable or constant volume applications. It manages duct pressure modulation, fan speed, redundancy and rotation, plus isolation and bypass damper control.
The VGD-100+ builds on the VGD-100 with expanded I/O configurable via the free Vari-Green companion app. It also includes BACnet and Modbus for seamless BMS integration.
An Ethernet connection to the facility network enables a full, product-specific graphical interface for unit monitoring and control—no BMS required.
