The lead controller polls the controllers from all the A/C units in the work
group and calculates the averaged value of their Temperature sensors,
Humidity sensors and optional Underfloor Pressure sensors. It also
determines the minimum (lowest) temperature sensor value and the lowest
humidity sensor value in the A/C group and conversely, determines the
maximum (highest) temperature sensor value and maximum humidity sensor
value in the A/C group.
Display Description Variables Default
Temp/Hum
Control the work group using the sensors connected to
individual A/C units (Local) or control the work group using
network sensor values transmitted from the lead controller.
To control by network sensors, select from the network
sensor values to be Lead, Average, Min or Max values. The
selections made in this screen will affect all the controllers
in the work group no matter which controller the screen is
accessed from.
