8. Annex 1: Master/Slave of Operation Mode
The Master/Slave of Operation mode only applies under the following conditions:
1. The AC system is VRV
2. The VRV system uses a Heat pump as outdoor unit
3. There more than one indoor unit in a unique system working at different modes
(Table 8.1)
If they are not matched the parameter is going to be ignored.
The Heat pump outdoor unit of a VRV system can only work in one mode (either Heat, Cool or
fan). The Master of mode is the indoor unit that defines which is the working mode of the outdoor
unit. If no unit has been chosen as the one that defines the working mode of outdoor unit, the
first indoor unit to be turned On is the one which is going to define and control the mode.
In a VRV system, there is only one device acting as Master of Mode. If more than one is configured
in this way, the system is not going to work properly. The configuration will be determined by the
Remote Controller of Daikin. The unit which controls the Operation mode must have installed a
Remote Controller.
When an INMBSDAI001R000 is configured as Master of Mode via the Remote Controller of its
indoor unit, it can control all the modes of the system. The Mode selection of the gateways
remaining and remote controllers installed in the indoor units remaining is going to be affected
by the one chosen as Master of Mode. These ones are going to acquire the Slave of mode
configuration, not being able to change to any mode selection out of the Table 8.1.
