The unit is factory calibrated to output a 10K-2, 10K-3 or 10K-3(11K) thermistor curve. The ROM receives data from a BAPI 418 or 900 MHz Receiver through a four-wire bus. Up to 127 different Output Modules can be connected to a single receiver to send multiple variables to the controller. The ROM is easily trained to a single transmitter temperature or humidity variable with a pushbutton and LED. The ROM is surface, 2.75” snaptrack or 35mm din rail mountable.
