INTRODUCTION

The Evolution Zone System consists of several intelligent communicating components which includes the Evolution Zone Control (or User Interface), Smart Sensors, Damper Control Module, variable speed furnace or FE fan coil, 2--stage AC or HP and Evolution Packaged Products, which continually communicate with each other via a four--wire connection called the ABCD bus. Commands, operating conditions, and other data are passed continually between components over the ABCD bus. The result is a new level of comfort, versatility, and simplicity.

All Evolution furnaces or fan coils are variable--speed and multi--stage for maximum flexibility, efficiency, and comfort. They support controlled ventilation, humidification, dehumidification, and air quality control. Either an Evolution (communicating) or a standard 24VAC controlled outdoor unit may be used.

When using conventional outdoor units, the Evolution furnace or fan coil provides the 24 volt signals needed to control them. Also, the Evolution Damper Control Module (P/N SYSTXBB4ZC01) allows connection of a Bryant HRV or ERV without the need for a separate wall control.

All system components are controlled through the wall mounted Evolution Zone Control, which replaces the conventional thermostat and provides the homeowner with a single wall control for all features of the system.

Design Considerations

The Evolution Zone system is unique because a bypass damper must not be used. This is possible due to the intelligence of the system and variable speed motor technology. For trouble--free applications, the following parameters should always be met:

1. Zones should be sized so that each zone can deliver at least the minimum airflow for the system in both heating and cooling modes.

2. Oversize duct work by 25% to avoid excess noise at minimum zone airflow.

3. Be aware that heating airflow may be higher than cooling airflow depending on equipment combination.

INSTALLATION, START--UP OVERVIEW

This instruction covers installation of the Evolution Zone Control only. Physical installation instructions for the indoor and outdoor equipment, Damper Control Module, and accessories are provided with each unit.

Setup, commissioning, operation, and troubleshooting of the Evolution Zone System are covered in this installation instruction. It is the guide to connecting the system components and

UIZ01--D

commissioning the system once all physical components are installed. Special screen prompts and start--up capabilities are provided in the Evolution System to simplify and automate the initial commissioning of the system.

S Install Evolution Zone Control according to this instruction.

S Install indoor unit, outdoor unit, and accessories according to

their instructions.

S Wire complete system according to this instruction.

S Setup, commission, and operate system according to this

instruction to assure a smooth and trouble free start--up.

INSTALLATION

Check Equipment and Job Site

Inspect equipment. File claim with shipping company prior to installation if shipment is damaged or incomplete.

Evolution Zone Control Location and Wiring Considerations

The Evolution Zone Control and Room Sensors should NOT be mounted:

S Close to a window, on an outside wall, or next to a door leading

to the outside.

S Exposed to direct light or heat from a lamp, sun, fireplace, or

other temperature--radiating objects which could cause a false

reading.

S Close to or in direct airflow from supply registers.

S In areas with poor air circulation, such as behind a door or in an

alcove.

Remote Room Sensor Option

A Remote Room Sensor can be used with the Evolution Zone Control to take the place of the User Interface internal temperature sensor. This allows the Evolution Zone Control to be mounted in areas with less than optimal airflow (such as near an exterior door, window or in a closet). The remote sensor can be wired to the terminal block connectors labeled S1 and S2 at the User Interface backplate, or the ZS1 and ZS1C connection at the Damper Control Module. In either case, the Evolution Zone Control will automatically detect the Remote Room Sensor and ignore its internal temperature sensor. It is also important to note the humidity sensor cannot be remotely located, so do not locate the Evolution Zone Control in an area where humidity sensing may not be accurate.

In addition, the Remote Room Sensor is a temperature sensor only, having no additional user inputs. This sensor is typically connected to the Damper Control Module and used to sense and control temperature in each zone.

Remote Sensor Averaging

Typically, one Remote Room Sensor is used per zone, but multiple sensors may be used and averaged in some applications. Averaging requires a special series--parallel wiring method with a specific number of sensors. See Fig. 2 in this manual for wiring diagram.

WARNING

ELECTRICAL OPERATION HAZARD

Failure to follow this warning could result in personal injury or death.

Disconnect power before routing control wiring.

All wiring must comply with national, local, and state codes.

Evolution Zone Control Location

The Evolution Zone Control User Interface is the command center for the Evolution Zone System and is typically located in Zone 1 to sense and control temperature in this zone. It should be located where it is easily accessible and visible to the adult homeowner or end user.

For accurate temperature measurement, the following guidelines should be followed:

The Evolution Zone Control and Room Sensors should be mounted:

S Approximately 5--ft (1.5 meters) from the floor.

S Close to or in a frequently used room, preferably on an inside

partitioning wall.

S On a section of wall without pipes or ductwork.

Fig. 2 -- Remote Room Sensor -- Parallel Wiring

Smart Sensor

Any zone may use a Smart Sensor. It provides a temperature display and buttons to adjust the desired temperature in that zone only. It also displays outdoor temperature and indoor humidity sensed at the User Interface. Only one Smart Sensor may be used per zone. They cannot be averaged like Remote Room Sensors. If a Smart Sensor is used in a zone, a Remote Room Sensor may also be used in the same zone. The Remote Room Sensor has priority over the Smart Sensor. The Smart Sensor will display the Remote Room Sensor temperature.

NOTE: Smart Sensors must be addressed to identify which zone it will control. See Smart Sensor Installation Instructions for details.

Wiring Considerations

Ordinary thermostat wire is recommended. Use 22 AWG or larger for normal wiring applications. Continuous wire lengths over 100-- ft. (3 m) should use 20 AWG or larger.

NOTE: ABCD bus wiring only requires a four--wire connection; however, it is good practice to run thermostat cable having more than four wires in the event of a damaged or broken wire during installation.

Each communicating device in the Evolution Zone System has a four--pin connector labeled ABCD. It is recommended that the following color code be used when wiring each device:

A — Green = Data A B — Yellow = Data B C — White = 24VAC (Com) D — Red = 24VAC (Hot)

It is not mandatory that the above color code be used, but each ABCD connector in the system MUST be wired consistently.

Shielded Wire

If the thermostat wiring will be located near or in parallel with high voltage wiring, cable TV, Ethernet wiring, or radio frequency equipment, then shielded thermostat wire can be used to reduce or eliminate potential interference. The shield wire should be connected to the C terminal, or ground, at the indoor unit. The shield wire should NOT be connected to any terminal at the user interface. Connecting the shield to ground at both ends can cause current loops in the shield, reducing shield effectiveness.

Locating Damper Control Module

All wiring is run back to the Damper Control Module. Select a location near the furnace or fan coil where wiring from the User Interface, each Remote Room Sensor or Smart Sensor, each damper actuator, and the equipment itself can come together easily.

The Damper Control Module is approved for indoor use only and should never be installed with any of its components exposed to the elements. The Damper Control Module (and zone dampers) may be installed in any area where the temperature remains between --4_F to 158_F(--20_Cto70_C), and there is no condensation. The cover must be installed to prevent damage from other sources. Do not locate where it will be accessible to children. It may be mounted in either vertical or horizontal position. Remember that wiring access is likely the most important consideration.

CAUTION

ELECTRICAL OPERATION HAZARD

Failure to follow this caution may result in equipment damage or improper operation.

To prevent possible damage to the Damper Control Module, DO NOT mount on plenum, ductwork, or flush against furnace or fan coil.

ABCD

A03193

Fig. 11 -- Wire ABCD Connector

Bypass Humidifiers

A bypass humidifier should be wired directly to the furnace or fan coil HUM and 24VAC COM terminals. The Evolution Zone Control will automatically energize the HUM output during a call for humidification.

Fan Powered Humidifiers

Most fan powered humidifiers produce internal 24VAC in order to energize upon a switch or contact closure. For this application, a 24VAC N.O. Isolation Relay (DPST) MUST be used to prevent mixing the internal humidifier power with the indoor equipment transformer. Applying 24VAC isolation relay coil to furnace or fan coil HUM and COM terminals will allow the Evolution Zone Control to automatically energize the HUM output during a call for humidification. The N.O. relay contacts will be used to energize the humidifier. See fan powered humidifier installation instructions for more details.

CAUTION

ELECTRICAL OPERATION HAZARD

Failure to follow this caution may result in equipment damage or improper operation.

Improper wiring of the ABCD connector will cause the Evolution Zone System to operate improperly. Check to make sure all wiring is correct before proceeding with installation or turning on power.

9. Push any excess wire into the wall. Seal hole in wall to prevent any air leaks. Leaks can affect operation.

10. Attach Evolution Zone Control to the mounting plastic by lining up the plastic guides on the back of the control with the opening on the mounting plastic and push on.

11. Perform installation of all other system equipment (i.e. dampers, humidifier, ventilator, UV lights, etc.).

12. Turn on power to equipment.

See wiring diagrams Fig. 8, 9, and 10 for connecting the Evolution Zone Control and Smart Sensors to the Damper Control Module. More information regarding Damper Control set--up and wiring can be found in Damper Control Module Installation Instructions.

See wiring diagram, Fig. 8, which includes an indoor communicating furnace or FE fan coil, with a 2-- stage Puronr refrigerant communicating outdoor unit. No additional OAT (outdoor air temperature) sensor is required because the Evolution Zone Control will use the temperature sensor inside the outdoor unit.

In a hybrid heat installation with a non--communicating heat pump, an OAT sensor must be installed or the heat pump will not run.

See wiring diagram, Fig. 9, for connecting an indoor communicating furnace or FE fan coil with a 1--stage air conditioning unit (non--communicating outdoor). An Outdoor Air Temperature (OAT) sensor may be installed (but is not required) at the indoor furnace or fan coil OAT terminals. When OAT sensor is applied, the Evolution System will provide enhanced system features and benefits.

See wiring diagram Fig. 10 for connecting an FE fan coil with a 1-- stage heat pump (non--communicating outdoor unit). When OAT is applied, the Evolution System will provide enhanced system features and benefits.

NOTE: For other applications not listed, refer to the Network Interface Module (NIM) Installation Instructions.

Humidifier Connection

A 24VAC bypass or fan powered humidifier may be installed. NOTE: Do Not Use a traditional humidistat to control humidifier

operation. If a humidifier is installed, let the Evolution Zone Control operate humidifier.

CAUTION

EQUIPMENT HAZARD

Failure to follow this caution may result in equipment damage.

Do not apply 24VAC fan powered humidifier (with internal power supply) direct to indoor unit HUM and COM terminals.

INITIAL POWER--UP

NOTE: Refer to Functional Overview (Fig. 12) to become

familiar with key function buttons such as “System On/Off”, “Zone”, “Fan”, “Left--Side” and “Right--Side” buttons, etc. These function buttons will be used frequently during setup.
