 RB unit can be switched cooling priority and heating priority by using RB 
unit PC board CNA01 or CNA02.

 

 The "external input priority mode" must be set by changing DIP switch 
SET2-1, 2 on PC board of RB unit.

 

 A twisted pair cable (22AWG) should be used. Maximum length of cable is 
150m.

 

 Use an external input cable with appropriate external dimension, depending 
on the number of cables to be installed.

 

The wire connection should be separate from the power cable line.
