Phason Supra-RS 16 Stage Control

QC Supply Part #: 11725
Shipping: Standard
Availability: In stock

Reliability, versatility, and value in one complete control package.


Phason's Supra 16-stage control automatically monitors and controls the temperature in up to four separate zones by operating ventilation equipment like fans, heaters, inlet actuators, and curtain machines. It features an easy-to-use keypad and menu system. The four-line, backlit LCD display shows current and past environmental conditions and alert conditions.

Supra is ideal for poultry, livestock, greenhouse, and light-industrial buildings. The optional humidity control ability allows you to connect a Relative Humidity Sensor (sold separately) and adjust ventilation during high humidity.

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. 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.

It features pluggable relays to allow you to easily remove and replace a damaged relay.
