10k Ohm or Digital Input
The universal input, when configured as a 10k ohm or digital input, accepts a 10k
ohm resistance input or a digital input such as a switch, also known as a cold
contact.
The 10k ohm resistance range accommodates 10k ohm thermistors used in space
temperature sensors or duct temperature sensors, or a 10k ohm potentiometer used
as a setpoint offset.
Use the conversion table for resistance input of more than 10k ohm. The digital
range accommodates the occupancy contact, bypass switch, and window switch.
See Figure 9 for wiring information for both 10k ohm resistance and digital inputs.
