System Screen with Rack View of Sensors

The System Screen with Rack View of Sensors will display the average, maximum and minimum of

all connected sensors for the supply, return and remote sensors.

This system screen display is calculated using information from the connected units in the unit two

unit (U2U) network. If the unit is stand along, the information displayed will represent values only

from that unit.
