The V3000 is a networked electronic control designed by CIAT to control non-independent air conditioning comfort units (fan coil units, cassettes, ductable units...) operating in 2-pipe, 4-pipe, 2-pipe/2-wire systems using recirculated air. It actuates 24 V three-position valves to control the water supply and thus ensures optimum control of ambient temperature conditions. Unlike a thermoelectric motor, this type of motor can stabilise any valve opening from 0 to 100% in accordance with the control system requirements. The V3000 controller is available as a flush-mounted version, factory-fitted to sill-mounted fan coils, and a wall-mounted version requiring connection by the installer. A radio-frequency remote control is available for cases where wiring is not possible (renovations, etc.) The V3000 communicates over the international open KNX protocol (ISO 14543-3), allowing it to be completely interoperable with all other devices on your site.
The V3000 uses Proportional-Integral-Derivative (PID) control to simultaneously operate an air conditioner’s valves, electric heater and fan speeds. It comes with display or dial terminals to optimally adjust indoor comfort conditions. The factory-set control parameters (PID, deadband ventilation, etc.) can be adjusted on the display terminal. The V3000 can manage the Master/Slave functions via a Konnex bus (bus supply optional) if it is not connected to a BMS. The V3000 automatically controls CIAT’s HEE concept to improve the energy efficiency of CIAT’s fan coil units: - Modulating output for adjusting the fan speed to room needs. For further information on how this control operates and the many configuration possibilites, please consult our documentation.
