Manual Analog Override Switch
Initial installation or trouble shooting can be smoother and much less costly by adding the RIBMNA1D0. It allows you to
manually control an analog output without accessing complicated algorithms in a controller. An indicator is provided for
visual confirmation of percentage output. When you are finished, you can switch back to auto to put the controller back
in control.

The self-calibrating current sensor begins its 30 second self calibration process the first time current is applied within the operating
range. This procedure uses the user selected differential to set the trip threshold at a 15% or 25% level. Selection is completed prior
to install using the appropriate DIP switch setting, keeping the installer’s hands away from possible shock hazard, as well as saving
installation time.

Echelon® Thermistor-In Application
A thermistor is used to read the temperature of a room or area. That data is fed back to the LonWorks® system. When the
temperature is out of range, the relay is commanded by the network, activating the exhaust fan, heater, or other
device. A current sensor is used to feed back load status to the network. If there is a command and status mismatch, the
network can issue an alarm to the operator’s console.
