USER-FRIENDLY SOLUTIONS FOR HVAC
FAN-COIL UNITS CONTROLLERS
Models available with On/Off, floating or Proportional control with manual/automatic fan speed selec-
tion. Some models (e.g. AXCU22/WMB) offer electric heater, automatic S/W change-over, window
contact and ModBus connectivity.
PARAMETER-SETTING CONTROLLERS
OMNIA® is the name of our range of digital controllers with 9 Inputs/Outputs for Temperature, Humid-
ity and Pressure control. With P+I action, 4 control loops, 24Vac or 230Vac power supply, outside tem-
perature compensation, low / high temperature/humidity limits, enthalpy control, free cooling. Models
with RS485 provide Modbus connectivity, Real Time Clock, daily & weekly programs. All air handling
units, including those with variable speed fan, are easily controlled by OMNIA controllers.
LIBERTY controllers are slightly bigger than Omnia controllers, with 19 I/Os and also include additional
I/O modules. Display can be in-built or remote.
All these ddc controllers are parameter-setting. No configuration tool is needed.
CONTROLS FOR INDUSTRIAL THERMAL PROCESSES
Digital controllers with PID action (Proportional, Integrative, Derivative), with relay and analogue out-
puts, display with set-point and actual values, Pt100 temperature sensor, suitable to applications with
hot water service, plate heat exchangers, industrial thermal processes and whenever high accuracy
control is required.
PROGRAMMABLE CONTROLLERS
OMNIA Pro programmable controllers have 6 digital + 5 analogue Inputs and 5 digital + 3 analogue Out-
puts, 2 triacs, I/O expansion modules, in-built or remote display, ModBus connectivity RS485 and RTC
(option), Temperature & Humidity room sensor with display.
Applications include: AHUs with heating/cooling/humidity control, frost protection, compensation,
optimization, free cooling, electric heater, heat pump. Central heating, hot water service, boliers and
chillers sequencing and more. Models with with RS485 can be remotely monitored by GT Touch Screens.
Maximum number of controllers monitored by one GT touch screen: from 10 to 40 controllers, depend-
ing on the architecture.
TOUCH SCREEN THERMOSTATS
AXT are user-friendly touch-screens for heating, cooling and many applications with 2-pipe/4-pipe
FCUs, including electric heater, manual or automatic S/W change-over, remote control.
ROOM CONTROLLERS
Not only FCU control! These DG8000 controllers perform room control management e.g. badge con-
tact, room power input, window contact, occupancy control, alarms. Display panel frame can easily
customised. Thanks to ModBus connectivity, these controllers are easily monitored through our GT
touch-screens, thus representing an ideal solutions for hotels, hospitals, offices.
