End-users may configure five (5) settings through this portal including the cycle time of both air conditioners, the auxiliary compressor status and enable time, and if installed with the Option K4 – Open Door Kill Switch, the open door delay time prior to the system powering off. A hardwired Ethernet connection is required. Compatible with Redundant Systems only.
