Back Light Time-out
The LCD is back-lit in the NRM and lights up when the fan or °F/°C push
button is pressed or the dial is turned. The back-light time-out is set in the
Back-light Time-out
configuration property. The factory default setting is
30 seconds. A value of 0 disables the back-light; a value greater than 60
keeps the back-light permanently on.
Temperature Units on Display
In NRM models without the °F/°C push button, the temperature units on
the display are determined by the
Temperature Units
configuration
property.
In NRM models with the °F/°C push button, the
Temperature Units
configuration property determines the temperature units on the display at
start-up, but the units are toggled between °F and °C by pressing the push
button.
Physical Address
The NRM has a physical address that you must set in the
PhysicalAddress
configuration property in the Room Sensor object of the
FX controller.
Non-addressable NRM models have a fixed address of 191, which is the
default setting of the Room Sensor object. Addressable NRM models
include DIP switches, allowing you to set the physical address between
191 and 194.
Note:
You must cycle power to the NRM (disconnect/reconnect the
NRM or cycle power to the field controller) for the address change to take
effect.
