Control Wiring Termination

In some cases with relatively big HVAC systems, where the total length of the wiring is high, control wire termination may be required. Termination can also be helpful if a control communication is noisy as a result of external electromagnetic influence. Termination can be easily made on CoolMasterNet side. To do it turn ON DIP Switch S2 - for line L1 and/or S3 - for line L2 as shown below. Rest of the DIP Switches should not be changed.
