ConnecngInputsandOutputs
Nailor EZvav series controllers have precongured inputs and outputs to support only the supplied programs and applicaons.
• For input and output connecon informaon, see the topic Applicaon drawings on page 29.
• To connect room temperature sensors, see the topic Connecng room temperature sensors on page 9.
• To connect a DAT sensor, see the topic Connecng a DAT sensor on page 10.
• For the BACnet object descripons of the inputs and outputs, see the topic BACnet objects on page 44.
ConnecngRoomTemperatureSensors
Connect any of the following sensors to the RJ-45 thermostat and sensor jack. The controller automacally detects the type of
sensor. No programming or conguraon is required.
• STE-6014W36
• STE-8001W36
• STE-8201W36
Connect the controller to sensors with standard Ethernet cables up to 75 feet long.
