This function enables the facility administrator or maintenance person to acquire and register the information about all air conditioners connected to VRF system.

(a)  Scan settings

• Select “Scan All” or “Scan Meters”.
  
  • When “Scan All” is selected, outdoor unit, indoor unit, electricity meter, and RB unit connected to VRF network are all scanned and registered.
  • When “Scan Meters” is selected, only electricity meter is scanned and registered.

• Set whether to enable “Bus Priority”.

  • Selecting the “On” is recommended for safe scanning. If you do not stop the operating indoor unit, select “Off”.

• Status
  • Running: Outdoor unit (refrigerant system) is detected by the last scanning.

(b)   Electricity Meter Address Range  (Set only for “Scan Meters”)

• Sets the range of electricity meter to be scanned to 0 to 199.
