A maximum of 3 extension modules per RMK770 can be used.
Prior to attaching an extension module, the plant must be disconnected from power.
The order in which the extension modules are fitted is not mandatory but must accord
with the settings made on the controller.
When selecting the plant type, an extension module is automatically preconfigured, if
required. This can be changed in the basic configuration.
