Mounting the controller
This chapter gives recommendations and requirements for mounting a
Tracer ZN521 zone controller.
Location recommendations
Trane recommends locating the Tracer ZN521 zone controller:
• Near the controlled piece of equipment to reduce wiring costs
• Where it is easily accessible for service personnel
• Where public access is restricted to minimize the possibility of tam-
pering or vandalism
The controller can often be mounted inside the wiring enclosure of the
associated mechanical equipment.
Operating environment requirements
Operate a Tracer ZN521 zone controller in an indoor environment that
meets the following requirements:
• Temperature: from 32°F to 140°F (from 0°C to 60°C)
• Relative humidity: 5–95%, noncondensing
