The Intelligent Controller is a centralized air conditioning management system dedicated to PAC and GHP for small
and medium sized buildings.
Number of connectable units ········• By connecting communication adaptors to one Intelligent Controller, up to
256 indoor units can be connected.
•Up to 120 outdoor units can be connected.
Display ·········································· • Touch panel type 6.5-inch TFT color (640x480 pixel VGA) LCD display
 Operation functions······················· •Start and stop, temperature settings, operation mode selection, fan speed
settings, fan direction settings, ventilation etc.
 Operating monitoring ···················· •All unit monitoring of operation status (operating/stopped, operation
mode, alarms)
•Display of alarm logs
•One-operation checking of all filter cleaning signs and engine oil
inspection signs
•External output of all errors, external output of all operations (relay
connections)
 Program timers …………………… •Up to 50 types of weekly timers can be programmed by combining 50
types of daily timers (50 times per day).
 Air conditioning energy
distribution ····································· •Recording and display of accumulated operating time and total number
of operations for each indoor unit.
•Calculation of gas and electricity distribution ratios and energy amounts
used (m3, kWh) for each indoor unit and each tenant.
•Distributions are available in two modes: the “simple distribution” calculated
based on the operating time and “loaded distribution” calculated based
on the actual air conditioning capacity, respectively. (In order to make
operation in the “Loaded distribution” mode, the air conditioner side needs
to be adaptable to the “Loaded distribution”.
•Distribution by time zones (regular hours, out of hours, special days).
•Recording of up to past 24 months of cut-off data.
