14.3 Setting the outdoor unit model via DIP switch S1
14.3.1 For FDC outdoor units: Set DIP switch S1 on the CompTrol Interface
Procedure for FDC outdoor units
1. Set the DIP switch SW4-3 to ON on the outdoor unit PCB of the FDC outdoor unit (see other
applicable documents: FDC series Technical Manual).
2. Identify which FDC outdoor unit is installed on site (see “Table 51: Setting the outdoor unit
model with DIP switches S1-5 to S1-8” on page 71).
3. Set DIP switches S1-5 to S1-8 in line with the FDC outdoor unit installed on site (see “Ta-
ble 51: Setting the outdoor unit model with DIP switches S1-5 to S1-8” on page 71).
