Control Features
The following control functions are standard features on units with Tracer UC400, ZN010, ZN510,
ZN520, or UC400.
Occupied/Unoccupied Operation
The occupancy input utilizes a binary switch (i.e. motion sensor, timeclock, etc.) that allows the zone
sensor to utilize its unoccupied internal setpoints.
Random Start
This feature randomly staggers multiple unit startup to reduce electrical demand spikes.
Warmup
The two-position fresh air damper option closes during the occupied mode when the space
temperature is three degrees or more below the heating setpoint temperature. The damper
remains closed during warmup until the space temperature is within two degrees of the heating
setpoint temperature.
