EWC Controls ULTRA-TALK 3000 Technical Bulletin

®
Forced Air Zone Controls
The patented UT3000 Zone Control System has been enhanced to provide
intelligent zone control of the Daikin FIT™ and ComfortNet™ communicating
HVAC systems or 24volt legacy HVAC systems. Create 2 or 3 air zones with a
single panel or "twin" two UT3000's together to create a 4 or 5 zone system. Use
EWC® 24volt motorized dampers and any off-the-shelf 24volt thermostat or
compatible communicating thermostats. Features like Automatic Equipment
Recognition, Modulating and Staged BTU capacity control, Dual Fuel
functions, Energy Saving features and Precise Control of Supply Air Target &
Limit set-points still come standard. Even the LCD display has been enhanced
to include easy to read "System Status" messages. EWC® Controls raises the
bar again and sets another new standard for Residential HVAC Air Zoning.

addition, all UT3000 programming is
performed at the LCD.

A total of 4 green Pulsing LED's are provided to
indicate a Comm Link has been established with each
LED's
Communicating Thermostat network and the HVAC
Communicating System network. A series of Rapid &
Random Pulses indicate a successful comm-link and
data transmission. Otherwise, each Comm LED will
blink at a slow rate for non-communicating devices.
The UT3000 comes pre-loaded with Default Operating
Parameters (See Page 2, Table 1) for Zoned HVAC
Systems. The Default Programing means less work for
&
the Installer, but also allows Fine Tuning of the System
to Optimize Performance and Personal Preference. The
UT3000 operates in Staged and Modulating mode at all
times. Multi-Stage and Modulating Equipment will be
operated in a manner that maximizes efficiency,
maximizes temperature control & improves system
performance.
The UT3000 includes a SPDT Indoor Air Quality Dry
Relay (IAQ Relay), with a digital & 24v Input
Trigger. It can be used to interlock and control
* Fresh Air Damper * Whole House Humidifier
The UT3000 must detect a Fan, Heat or Cool demand
from one or more communicating zone thermostats or
legacy non-communicating zone thermostats, before
the IAQ relay will energize. See page 8.
