Supra 16-stage environmental control
Powerful, versatile, and cost effective

Supra automatically monitors and controls the temperature in up to four separate zones by operating ventilation equipment such as fans, heaters, inlet actuators, or curtain machines.
Supra has two 7-step growth curve programs you can configure for up to 250 days. The easy-to-use keypad and menu system make it easy to program the control.
The four-line, backlit LCD display shows current and past environmental conditions, as well as any alert conditions.
Supra is ideal for poultry, livestock, greenhouse, or light-industrial buildings and is compatible with any ventilation strategy: natural, forced, tunnel, and chimney ventilation.
Humidity monitoring and control
Supra's humidity control ability allows you to connect a Relative Humidity Sensor and adjust ventilation during high humidity. When humidity levels are high (you define the upper and lower limits), the Supra automatically adjusts the ventilation equipment to help lower the humidity.
Water usage monitoring
Water usage monitoring has never been easier. Supra allows you to connect a water meter with pulse output and monitor water usage in your building. The status display shows daily water usage in liters or gallons and the input log stores this information so you can view it anytime. It's that easy.
Temperature setback/DIF control
Temperature setback allows you to automatically change the temperature set point for a specific period of time during the day.
In greenhouses, temperature setback (different method/DIF) is a means of maintaining different day/night temperatures. Using temperature setback, you can maintain a lower temperature set point during the critical dawn hours, and then return to the normal set point later in the day.
Optional accessories—enhance your Supra
Convenient accessories such as the SupraSaver and Intaglio allow you to store and transfer your Supra settings and configuration and update the firmware version of your Supras.
The DC expansion kit allows you to connect equipment that requires a 0 to 10-V input, such as variable frequency drives.
Using the SupraWare software, you can connect up to 32 Supras together and monitor and configure them from a central computer.
