ActronAir Remote Sensing System provides wall-mounted temperature sensing for ActronAir residential ducted systems in applications where the wall controller is not in the optimal sensing location, measuring the return air temperature at a separate sensing point and transmitting the data to the indoor PCB for more accurate zone temperature control. Remote sensing is particularly effective in open-plan rooms where the wall controller is located near a heat source or cold air register that would otherwise skew the sensed temperature. Isolate power at mains before installing or replacing any remote sensing components.
