These controllers meet the requirements of the following applications:

  • Air handling units
  • Chillers
  • Boilers
  • Cooling towers
  • Heat-exchangers
  • Pumps
  • Lighting control

This controller has various software configurable universal inputs and software configurable universal outputs, and covers all medium to large-size industry-standard HVAC applications.

Rugged hardware inputs and outputs eliminate need for external protection components, such as diodes for 12V DC relays.

Increased Energy Efficiency

Improves energy efficiency when combined with:

CO2 sensors as part of a demand-controlled ventilation strategy that adjusts the amount of fresh air intake according to the number of building occupants

Variable-frequency drives to adjust motor speed according to the instantaneous demand of the application.
