Tracer® ZN.010
and ZN.510
Binary Inputs
BIP1: Low
Temperature
Detection
Option
BIP2: Condensate
Overflow Detection
Option
BIP3: Occupancy Sensor
The factory hard wires the low temperature detection sensor to binary input #1 (BIP1) on the Tracer® ZN.010 and ZN.510. The sensor defaults normally closed (N.C.), and will trip off the unit on a low temperature diagnostic when detecting low temperature. In addition, the Tracer® ZN.010 and ZN.510 control unit devices as listed below:
Fan: Off
Valves: Open
Electric heat: Off
Damper: Closed
Note: See the “Diagnostics” section on page 50 for more information.
The factory hard wires the condensate overflow sensor to binary input #2 (BIP2) on the Tracer® ZN.010 and ZN.510. The sensor defaults normally closed (N.C.), and will trip off the unit on a condensate overflow diagnostic if condensate reaches the trip point. In addition, the Tracer® ZN.010 and ZN.510 control unit devices as listed below:
Fan: Off
Valves: Closed
Electric heat: Of
Reference Table 6 for the Tracer® ZN.010 and ZN.510’s six binary outputs.
Binary input #3 (BIP3) on Tracer® ZN.010 and ZN.510 is available for field- wiring an occupancy sensor, such as a binary switch or a timeclock, to detect occupancy. The sensor can be either normally open or normally closed. Reference Table 5 on page 43.
