Datamate Software

Datamate is a customer software tool for all controller communications. There are two versions: Datamate Base, and Datamate Advanced. Datamate Base works on an IBMcompatible Personal Computer (PC), or a Handheld PC or Pocket PC™ running Windows CE. Datamate Advanced works only on an IBM-compatible Personal Computer.

With Datamate, you can back up, restore and edit any APOGEE® database (but only Datamate Advanced allows you to edit points offline). Backing up and restoring a database is accomplished while connected to any APOGEE® field panel, or to the Automation Level Network (ALN) or Field Level Network (FLN) device in question. A modem and telephone lines can also be used. Databases can be saved for permanent storage or used as backup.

For more information on Datamate software, refer to the appropriate user guide for the version of Datamate you are using (Base or Advanced), or contact your local Siemens Building Technologies, Inc. representative.

Product Overview

Introduction

The Unit Vent Controller—0 to 10V Output is the Siemens Building Technologies, Inc. Terminal Equipment Controller (TEC) used in unit ventilator applications. See Figure 1. It provides Direct Digital Control (DDC) for five applications. The controller can operate as an independent, stand-alone, DDC room controller or be networked with an APOGEE field panel.

The controller provides all termination, input/output, system and local communication connections. See Figure 1. The controller hardware consists of the controller with cover and mounting bracket.

Temperature Sensors

Temperature sensors used with the Unit Vent Controller—0 to 10V Output include an electronic room, mixed air or discharge air temperature sensor.

Room Temperature Sensor

The Terminal Equipment Controller room temperature sensor connects to the controller by means of a cable pre-terminated at both ends with a 6-conductor RJ-11 plug-in connector. See Figure 1 for the location of the room temperature sensor/Man-Machine Interface (MMI) port.

Siemens Building Technologies, Inc.

Introduction

Mixed Air/Discharge Air Temperature Sensor

The mixed air/discharge air temperature sensor is a 100K ohm thermistor that connects to the controller at the screw terminals for Al 3.

For more information about Siemens Building Technologies, Inc. temperature sensors, contact your local Siemens Building Technologies, Inc. representative.

Actuators

Damper Actuators

The damper actuator used with the Unit Vent Controller—0 to 10V Output is a 0 to 10V spring return electronic damper motor that positions an outside air damper. A 0 to 10V electronic damper motor can be used to position a face-and-bypass damper.

Valve Actuators

The valve actuators used with the Unit Vent Controller—0 to 10V Output are modulating spring return and non-spring return electronic valve motors that position the valves.
