GREE GMV5 HR HEAT RECOVERY UNITS
103
On the master module, the SA8 DIP switch must be set again, the SA1 DIP switch cannot be
further set, and other DIP switches retain the factory settings without special requirements.
Function DIP switches must be set when the ODU is powered off, and then the settings are
valid after the ODU is powered on.
If above DIP switch setting is incorrect, unit will work abnormally and compressor may even be
damaged.
Meanings and setting methods of function DIP switches are as follows:
3.1.1 Unit Capacity DIP Switch (SA1_capacity)
The unit capacity DIP switch (SA1_capacity) has been set upon factory departure. It is unnecessary
to further set the DIP switch. In addition, users are not allowed to change the DIP switch settings.
Otherwise, the system may work abnormally or even the compressor may be damaged.
3.1.2 Centralized Control Address DIP Switch (SA2_Addr-CC)
The centralized control address DIP switch (SA2_Addr-CC) indicates the centralized control
address required when different refrigerating systems are controlled in a centralized manner. The default
factory setting is "00000".
If it is not required to use centralized control between multiple refrigerating systems, this DIP switch
can retain the factory settings without being changed.
If it is required to use centralized control between multiple refrigerating systems, set the DIP switch
according to the following methods:
(1) The DIP switch must be set on the master unit. Otherwise, the setting is invalid.
(2) On the same refrigerating system, the centralized control address DIP switch (SA2_Addr-CC)
on a non-master unit is invalid, and it is unnecessary to change the settings.
(3) The centralized control address DIP switch (SA2_Addr-CC) on the master unit of a refrigerating
system must be set to “0000X”, and this system is the master system.
(4) The centralized control address DIP switch (SA2_Addr-CC) on the master unit of other
refrigerating systems must be set as follows:
SA2
