Setting Indoor Group Address

Indoor Group Address (centralized address) is required for proper CoolMasterNet operation. Without Group Address Indoor unit is not visible and can not be controlled by CoolMasterNet or any other Daikin equipment. Group Address is set with wired remote controller. Here is a simple sequence of operations for Daikin BRCE61 wired remote controller to set Group Address.

• Press and hold Cancel button for a few seconds
  

• Scroll down to Group No. setting function and press Menu/Enter button
  

• Program Group Address and then press Menu/Enter to save address
  

Remember if Indoor unit can not see a CoolMasterNet you won't have the Group Address menu option. So make sure the CoolMasterNet is wired to F1 F2 HVAC line and powered.

Reading Thermostat ambient temperature instead of return air

CoolMasterNet will read ambient temperature measured by Thermostat - local wired controller (like BRC1E72) if following field settings had being done on Thermostat:
Setting 10-2 = 03 - Only the thermostat thermistor will be utilized by Indoor unit.
Setting 10-5 = 02 - Room temperature value reported to CoolMasterNet by Indoor is taken from Thermostat

KRP928A2S Auto Mode Control

To enable proper Auto Mode control from CoolMasterNet of the Indoor Unit connected via KRP928A2S adapter, make sure to configure SW3 switch to GLO position:

KRP928xxx Limitations

This is taken from original Daikin document "Interface Adaptor for DIII-NET" :

• The range of temperatures that can be set from the central controller is 18°C to 32°C in cooling and 14°C to 28°C in heating.
• Fan operation cannot be selected from the central controller or wired remote controller.
• Group control (i.e., control of multiple indoor units with a single remote controller) is not available.
• Monitoring is not available of the thermo status, compressor operating status, indoor fan operating status, electric heater, or humidifier operating status.
• Forced thermo off, filter sign display and reset, fan direction and speed settings, air conditioning fee management, energy savings instructions, low-noise instructions, and demand instructions cannot be made.
