RZ VAV-L: Application Specific Controller

The RZ VAV L is a zone controller intended for VAV heating and cooling applications with one or two stages of reheating. The controller keeps a constant temperature in the zone by controlling the air flow and heating stages. By using a carbon dioxide sensor, the air quality can be controlled in the zone.
The RZ VAV L is equipped with an integrated, static air velocity transducer and a motorized bidirectional actuator in a single package.
The differential pressure air velocity transducer requires a minimum of maintenance. Thus it is also well suited to be placed in the zone return air duct.The controller is a LONMARK® compliant device aimed at communicating on a LONTALK® TP/FT-10 network via a twisted-pair, unpolarized cable. It is able to operate both as a stand-alone unit and as part of a system. All relevant network variables can be monitored and configured via the Network Plug-in or, locally, via the intelligent thermostat device (RZ VAV STC-300) or the commissioning device RZ VAV TOOL.

FEATURES

Plug-on input terminals for a thermostat, communications, power, and four external      devices.

Two input ports for the integrated air velocity sensor.

Plug-terminals for three external outputs.

A 12-position DIP switch for setting up the initial application/equipment configuration.

Indicator lamps for communication, power, and self-test.
