Function introduction of central controller
1. 40VCC617FQEE can control MRV and SuperMatch (including single split and multi split). 128 indoor units can be
controlled when used with MRV and 128 indoor units when used with single split & SuperMatch.CD.
When controlling MRV, 40VCC617FQEE should be used together with converter.
converters are hand in hand connected to 40VCC617FQEE. How to choose MRV: System Settings-Local-Type
Select-MRV.
2. When 40VCC617FQEE controls the SuperMatch series, each indoor unit requires one 40VCAR17FQEE as the
adapter. The 40VCAR17FQEE adapters are connected with 40VCC617FQEE hand in hand.
How to choose multi: System settings - Local - Type Select- Single.
3. Main functions of central controller
CD Monitoring and controlling indoor running state such as ON/OFF, Mode, Fan, Set temp. and error code.
• Zone setting, editing and deleting.
• Realizing ON/OFF, mode, fan, temperature setting for single/zone/all indoor unit(s).
• Checking indoor unit detailed information such as real temperature, coil temperature, error code.
For MRV, three kinds of controlling mode:
LIFO, Central & Force can be selected for indoor units; while only Force &
LIFO mode can be selected for single split unit.
LIFO: the indoor unit will execute the last command sent by central controller, Wired controller or remote controller.
For example,if central controller sends a low fan speed command and wired controller sends a high fan speed
command, the indoor unit will execute high fan speed command.
Central: Central controller enjoys all functions while wired & remote controller can only control ON/OFF of indoor
units.
Force: Central controller enjoys all functions while wired & remote controller cannot control indoor units.
controller will turn all indoor units o󰀨.
When it receives a re alarm signal, the central controller will turn all indoor units o󰀨.
4 Weekly timer setting: Weekly timer for one or some or all units can be set and will run in a cycle.

For every AC system, address starts from No. 1 to last indoor unit of the system. If a total of 20 indoor units are
connected in one system, the address should be 1-20; if 50 units are connected in one system, address should be
1-50; the biggest address is 64.
Note: Every indoor address starts from 1.
