The One of a Kind UT3000 Zone Control System provides intelligent

control of a communicating HVAC system or 24volt legacy HVAC

system at a maximum of three zones using 24volt motorized dampers

and any off-the-shelf 24volt thermostat or compatible

communicating thermostat. The UT3000 is 100% plug and play when

connected to a communicating HVAC system and network

thermostats. The UT3000 includes features such as Proportional

Operation, Automatic Equipment Recognition, Dual Fuel Functions

and Precise Control of Supply Air Target & Limit set-points.

EWC® Controls raises the bar again and sets another new standard

for Residential and Light Commercial HVAC Air Zoning.

Control Any Communicating HVAC

system based on the ClimateTalk™ Open

Protocol. Or any 24volt 2 Heat / 1 Cool

Gas/Electric system or 2 Heat / 1 Cool

Conventional or Dual Fuel Heat Pump.

The UT3000 panel features automatic

changeover from any thermostat allowing

for individual zone comfort from the

zoned HVAC system.

The Liquid Crystal Display scrolls to

show current zone thermostat demand

input and HVAC system demand output.

In addition, all programming is performed

at the LCD.

In addition to the LCD, a total of 5 colored

LED’s provide indication of the HVAC

system status and mode of operation.

A total of 3 green LED’s labeled Zone 1

thru Zone 3, are also provided to indicate

which dampers are energized to Open.

A total of 4 green Pulsing LED’s are provided to

indicate a Comm Link has been established with each

Communicating T-stat and/or the Communicating

HVAC system. A series of Rapid & Random Pulses

indicate a successful link and data transmission.

Otherwise, the Comm LED’s will blink On & Off

very slowly for non-communicating devices.

The UT3000 includes a SPDT Dry Relay with an

Input Trigger that can be used to Connect, Interlock

and Control Ancillary IAQ devices:

Fresh Air Damper * Whole House Humidifiers

Heat Recovery Ventilator * Energy Recovery Ventilator

Whole House De-humidifiers * Combustion Air Damper

The UT3000 will start the Indoor Fan when the Dry

Relay Input is Energized. Connected Zone Dampers

operate normally and are not affected by the relay’s

function.

Four buttons are provided just below the

LCD screen. The buttons are used to scroll

thru the Menu on the LCD and make your

selections. Program the UT3000 and

select the features you like. Non-volatile

memory maintains your settings even

after a long power failure.

UT3000

The UT3000 comes pre-loaded with Default

Operating Parameters for Zoned HVAC Systems. The

Default Program Settings free the Technician from

Programming but also allows Fine Tuning of the

System to Optimize Performance and Personal

Preference. The UT3000 operates in Proportional

Mode at all times. Multi-Stage and Modulating

Equipment will be operated in a manner that

Minimizes Blower Speed, Maximizes Temperature

Control and Improves System Efficiency.

INSTALLATION INSTRUCTIONS MOUNT: Choose a suitable location to mount the UT3000 housing. Likely locations are the Return Duct, a Nearby Wall or Convenient Studs where plywood can be installed to support the housing. Avoid mounting the UT3000 on the Supply duct. Do not mount the UT3000 directly to any Air-Handler, Furnace, Hot Water Coil or Evaporator Cabinet to avoid damage to these devices. Follow National and/or Local Mechanical Code. Typical Up-flow Installation with DX Cooling OK EW CONTR OLS INC.

LCD Screen Programming Remember if you are installing a Communicating HVAC system, the programming is done for you. There is no need to perform these Programming steps. You can still program certain detail functions ie. (24v T-stat Type). Select only the functions you want or need. Your program changes take effect in real time and the UT3000 will remember your settings even after a power failure. When the power is restored, the UT3000 will re-configure the network automatically.
PAGE 4
LCD Screen Programming The UT3000 staging process is very unique. The difference between the Target Set-point and the Actual Supply Air temperature along with the SAS Response Delay determines how fast or slow the UT3000 will stage the HVAC system. Via the System (SYS) Output screen, (see the next page) the UT3000 will increase or decrease the System Output value so it can match the Target set-point. When the target is matched, the UT3000 will stop staging.
PAGE 5
LCD Screen Scrolling Displays Once the programming is complete and the System is functioning, the LCD screen will scroll and display the following data continuously. The HVAC system mode of operation is displayed including Supply Air and Outdoor Air temperature, Auxiliary/Emergency mode and Ancillary Functions. The UT3000 LCD will continuously Scroll data as to which Zones are actively calling for a Heating, Cooling or Fan Operation.

WIRING INSTRUCTIONS WARNING: THESE PANELS ARE DESIGNED FOR USE WITH 24VAC. DO NOT USE OTHER VOLTAGES! USE CAUTION TO AVOID ELECTRIC SHOCK OR EQUIPMENT DAMAGE. ALL WORK SHOULD BE PERFORMED TO LOCAL AND NATIONAL CODES AND ORDINANCES. USE 18 AWG SOLID COPPER, COLOR-CODED, MULTI-CONDUCTOR THERMOSTAT CABLE. Thermostat Wiring Communicating thermostats can be used on all zones for all applications. You can also mix Communicating thermostats with 24v thermostats.
PAGE 10
System Wiring The UT3000 panel was designed to be easy to wire up and operate. We have provided several typical field wiring diagrams to review. Your actual field wiring may vary. In full communicating mode, 4 wires are all that is required from each thermostat and to the HVAC system. The UT3000 will “Talk” to the HVAC system and “Talk” to the thermostats in order to automatically setup and start operating the HVAC system.
