Setting Indoor Group Address

Indoor Group Address is required for proper CoolMasterNet operation. Without Group Address Indoor unit is not visible and can not be controlled by CoolMasterNet. 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

BRC1E61-buttons.gif

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

BRC1E61-group-address-menu.gif

  • 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:
