Central Station EZ

The Central Station EZ is a central AC control that includes all the daily air conditioning management functionalities. Users can see and control what’s happening inside their facility from temperature to maintenance.

From the Central Station EZ central AC control system, you can select the target rooms and optimize the air conditioning according to the occupants’ needs. Available customisations include the turning on/off of the indoor units, modification of the temperature setpoint, fan speed and airflow direction

Use the scheduling function to meet your building’s AC needs. Up to 10 slots can be set for each day of the week. You can pre-cool/pre-heat selected rooms before opening hours, and schedule the AC to turn off during the building's vacant hours.

With Central Station EZ, facility managers can always know when an air conditioning indoor unit requires filter cleaning. A filter symbol appears on the AC control panel screen and indicates which indoor unit requires cleaning.

In case of AC malfunction, the users are alerted with a visual symbol alarm. AC error code and time can be accessed from the screen. The error history can show up to 100 errors.

Connect a 3rd party equipment to the Central Station EZ for a smarter building operation. 2 input * and 2 output ports are available on the back of the Central Station EZ. Example: To improve building safety, add the fire alarm as an external input, so the fire alarm can trigger emergency stoppage of the AC. *4 output ports on Central EZ models sold in Japan and North America.

Instead of using one large centralized control system, some facility managers of big buildings may prefer to install several Central Station EZ in their offices. See how multiple Central Station EZ central air conditioning control system is installed at the Nippondaira Hotel in the video.

In other venues, one Central Station EZ can be installed on each floor. See how one Central Station EZ is installed on each floor of North Kellyville Public School in Australia in the video.

Connect the Central Station EZ to Hitachi air conditioning equipment via the exclusive H-LINK communication system. It enables flexible wiring, connecting at any point of the system. H-LINK is default for Hitachi VRF systems. Other types of Hitachi AC units can be connected using an H-LINK adapter * . *Confirm compatibility and models with your Hitachi Cooling & Heating representative.
