Master/Slave Setup
Chiller setup for dual unit (WDC) or two single (WSC) units with master/slave and or lead/lag control.
There are several menus that require modification to accomplish this setup. The first menu that has to
be modified is menu 26. One MicroTech controller has to be designated as the Master unit. The other
unit will be the Slave unit.
Set the toggle switch on the face of the MicroTech panel (master and slave units) to the stop
position. Go to menu 26 on the Master unit. Only the values that require changes will be discussed.

Config= This defines the communication link, com port type and MicroTech controller level. The
master unit must be set to L2-Master-Slave. This setting makes menu 23 available only on the master
unit.
(The slave unit must be set to L3TTY-Slave).
Master/Slave= Set this to 'Master' on the Master unit. (Set this value to 'Slave' on the slave unit).
This completes the setup of menu 26 on both the master and slave units.
