  • Unless asked differently, CoolMasterNet comes with only one line opened. If you wish to add another HVAC brand to a new line or change the current connected HVAC to a new line, you should first ask CoolAutomation support to make sure you have enough lines opened.

  • CoolMasterNet can be reconfigured from one brand to another from the HVAC Lines menu and corresponding position of DIP switches, located behind the door on the front, right-hand side of the device. For DIP switch positions, and list of the brands please refer to the Installation section and select the right brand.
