Product Name(s): Terminal Box Controller; Constant Volume Controller; Dual Duct Controller; Unit Conditioner Controller; Unit Vent Controller; Heat Pump Controller; Room Pressurization Controller; Laboratory Room Controller; Fume Hood Controller
Product Description: The TEC Series are secondary controllers with fixed I/O designed for specific types of air terminal and packaged HVAC equipment applications. They reside on the secondary P1 Field-Level Network, and can be programmed using either standard template-based methods (for common control sequences) or custom programmed.
Product Application(s): Terminal Box Controller - designed for pressure independent VAV air terminal applications with or without reheat options. Constant Volume Controller - designed for pressure independent temperature control and constant volume air terminal applications. Dual-Duct Controller - offered with one and two air velocity sensor configurations and are designed for pressure independent dual-duct VAV and constant volume air terminal applications. Unit Conditioner Controller - designed for pressure dependent boxes, fan coil units, and induction units. Unit Vent Controller - designed for unit ventilators for ASHRAE Cycle I, ASHRAE Cycle II, ASHRAE Cycle III, and Nesbitt Cycle W (0-10V controller only) applications. Heat Pump Controller - designed for water source heat pumps with ventilation or mixed air control and air to air heat pumps with ventilation and mixed air control. Single or multiple stage configurations are offered. Room Pressurization Controller - designed for room pressurization and room temperature control. The RPC controls a room's supply and exhaust terminal units to maintain differential flow between the supply and exhaust. Typical applications include isolation rooms, surgical suites, labs without fume hoods or wherever positive or negative pressurization of the room is critical. Laboratory Room Controller - designed for similar applications as the Room Pressure Controller, but adds the capability to interface with fume hoods and Siemens' Fume Hood Controller. Flow control speed of response listed at 1.5 sec. The pneumatic version uses 2 DO-to-pneumatic converters. Fume Hood Controller - designed for VAV control of laboratory fume hoods. The controller maintains face velocity as the fume hood sash is raised and lowered. This device must be used with Siemens' electronic or pneumatic Fume Hood Exhaust Terminal. An Operator Display Panel is also available. Face velocity is calculated from input parameters and sash position.

Additional Information
* Items in NV memory are not lost upon power or battery failure. Other types of NV memory such as EPROM, NOVROM, etc. do not directly impact system performance.
Can trend data be stored in this controller? No
How many total trend values can be stored? N.A.
What is the controllers role in trending? None. Trend point data is called by the SI and stored temporarily before being archived at the OWS.
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller?
When full, does controller automatically send up trend data, overwrite data, or stop logging data? N.A.
Programming Method(s) Pre-existing programs ('applications') are configured using Voyager. Voyager is a Windows-based program that allows users to communicate directly with any Terminal Equipment Controller to view, modify, or command point information. Initially, secondary control units must be configured locally, then address is kept in EEPROM allowing complete access and re-configuration capability from workstation or portable terminals.
Resident vs Non-Resident Program Execution Resident programming will allow control to function as stand-alone. Primary controllers or supervisory interface devices manage scheduling, trending, global control, and communication functions.
Scheduling
Resident/Supervisory. This controller supervises the scheduling of other controllers.
Resident/Stand Alone. This controller contains its own schedule.
Non-Resident. This controller is dependent upon another controller for its schedule.
None. This controller has no scheduling features.
