Taco Clar-asc-1 Clarity 3 Programmable Controller Instruction Manual

Taco CLAR-ASC-1 Clarity 3 Programmable Controller

DESCRIPTION

Taco Clarity3™ ASC series controllers are designed to operate unitary and terminal equipment. The integrated alarming, scheduling, and trending enable these BACnet Advanced Application Controllers to be powerful edge devices for the modern smart building ecosystem.
The factory-supplied programming covers common unitary applications. The controllers feature simple, menu-driven setup choices using an NS-100/200series digital sensor, which can be installed permanently as the room sensor or used temporarily as a technician’s service tool.
Alternately, quick configuration of controller properties can be done using NFC (Near Field Communication) from a smart phone, tablet, or computer (using TacoVision Lite™ app) while the controller is unpowered.
The Ethernet-enabled models can also be configured by connecting an HTML5-compatible web browser to the built-in configuration web pages.
To meet the most demanding building automation custom requirements, these controllers are also fully programmable. Custom configuration and programming, with wizards for application programming selection/configuration, are enabled by Taco Vision software.
The Taco Programming software additionally provide the capability of creating custom graphical web pages (hosted on a remote web server) to use as a custom user-interface for the controllers.

APPLICATIONS

Can be used with the following types of unitary equipment:

• Air handling units (AHU)
• Chilled beams
• Constant air volume (CAV) with external actuator
• Fan coil units (FCU)
• Heat pump units (HPU)
• Roof top units (RTU)
• Unit ventilators
• Variable air volume (VAV) with external actuator
  (Some applications require custom programming. See also Sample Installation on page 5.)
