Reliability, versatility, and value in one complete control

The Supra monitors and controls temperatures in up to four separate zones by operating ventilation equipment such as fans, heaters, inlet actuators, and curtain machines.

Humidity monitoring and control

Optional humidity control ability allows you to connect a Relative Humidity Sensor and adjust ventilation during high humidity.

Water usage monitoring

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 litres or gallons.

Temperature setback / DIF control

Temperature setback (also called different method or DIF) allows you to automatically change the temperature set point for a specific period of time during the day. For example, you can maintain different day/night temperatures.
