3. Group Control Operation

(Collective Operation and Control of Multiple Refrigerant Systems (2 to 16))

Multiple Mr.Slim air conditioners can be operated with the same settings (e.g., operation mode, preset temperature, etc.) by using 1 remote

controller. Each outdoor unit can be turned ON/OFF individually by the intake sensor.

Up to 16 refrigerant systems can be controlled as a group by 1 remote controller.

A refrigerant address must be set for each outdoor unit. Addresses "0" to "15" can be set with no duplicates. Address "0" must be set for one of

the outdoor units.

* In the case of simultaneous twin, triple and quad units, only 1 refrigerant system is used.

[Reference]

For 2-remote controller control, refer to "2. 2-Remote Controller Operation". However, when using both wired and wireless remote controllers,

receivers must be connected to indoor units that are connected by crossover wiring.

Connect an indoor unit having the highest functions among the group to the outdoor unit assigned to refrigerant address "0". <Refer to the example

given below> If indoor units with vanes are used with those without vanes, connect the outdoor unit to a unit with vanes.

Function specifications <Example>

In the case of multi type systems consisting of simultaneous twin, triple and quad units, the indoor units should not be connected

by crossover wiring. (Prohibited)

Outdoor unit address setting

For group control, an address must be set for each outdoor unit.

To set addresses to outdoor units, use the DIP switch SW1 (3–6) provided on each outdoor control board (initial setting: all are set to "OFF").

Address setting by SW1 is as follows.

* Checking the outdoor unit refrigerant addresses

To find the location of an outdoor unit with a specific refrigerant address, specify the address in self-diagnosis mode. The outdoor

unit will operate intermittently. (For details on using self-diagnosis mode.)

Group operation by multiple remote controllers

Up to 2 remote controllers can be connected to each group. For details, refer to " 2.2-REMOTE CONTROLLER OPERATION".
