 | Configurable Terminal Unit Controller with BACnet communication
The “CTU ARM 2…” series are a Configurable Terminal Unit Controllers designed to control various
HVAC applications.
The “CTU ARM 2…” series operates and controls Analog Inputs, Analog Values, Analog Outputs, Digital
Inputs, Digital Values and Digital Outputs.
The series is designed to control HVAC applications such as Fan-Coil, D/X Air Conditioners, Chilled and
Heated Beams, Variable Air Volume, Multi-Zone, Water Source Heat Pump and more.
The outputs of the “CTU ARM 2…” are ON/OFF, Proportional 0-10V, PWM, 4-20mA.
Wall panels and remote-control-interface may operate the controller by the end-users.
The device can be configured by the installer without the need of a PC and software tool, using a set of
on-board DIP switches.
The series is designed for field installation in a panel or enclosure or for mounting by original
equipment manufacturers (OEMs) on DIN-rail or directly on a surface.
Depending on the equipment installed, different types of terminals and relays are mounted.
“CTU ARM 2…” series is the next generation of BACnet-certified series “CTU2…”
The BACnet interface of the controllers complies with the ANSI/ASHRAE Standard 135-2023 for sharing
data with other devices on the network.
