Improper wiring or installation may damage Infinity Control System. Recognize safety information. This is the safety-alert symbol . When you see this symbol on the equipment and in the instruction manual, be alert to the potential for personal injury. Understand the signal words

DANGER, WARNING, and CAUTION.

These words are used with the safety-alert symbol. DANGER identifies the most serious hazards, which will result in severe personal injury or death. WARNING signifies a hazard, which could result in personal injury or death. CAUTION is used to identify unsafe practices, which would result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

INTRODUCTION

The Infinity System consists of intelligent communicating components (User Interface, variable speed furnace or fan coil, AC or HP), which continually communicate with each other via a four-wire connection called the ABCD bus. Conventional 24-volt signals on dedicated wires are not needed. Commands, operating conditions, and other data are passed continually between the components over the ABCD bus. The result is a new level of comfort, versatility, and simplicity.

An Infinity System consists of a Infinity Control™ (thermostat plus much more) and an Infinity furnace or fan coil. All Infinity 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 Infinity dual capacity (communicating), or a standard 24 vac controlled outdoor unit may be used.

When using conventional outdoor units, the Infinity furnace or fan coil provides the 24 volt signals needed to control them. Also, the Infinity Network Interface Module (NIM) allows connection of a conventional HRV or ERV without the need for a separate wall control.

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

INSTALLATION AND START-UP OVERVIEW

This instruction covers installation of the Infinity Control™ only. Physical installation instructions for the indoor, outdoor equipment and accessories are provided with each unit.

Setup, commissioning, operation, and troubleshooting of the Infinity System is covered only in this installation instruction. It is your guide to connecting the system components and commissioning the system once all the physical components are installed.

INSTALLATION

STEP 1 — CHECK EQUIPMENT AND JOB SITE

INSPECT EQUIPMENT — File claim with shipping company, prior to installation, if shipment is damaged or incomplete.

STEP 2 — INFINITY CONTROL™ LOCATION AND WIRING CONSIDERATIONS

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or possible equipment damage.

Disconnect Power before routing control wiring.

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

INFINITY CONTROL™ LOCATION— The Infinity Control™ is the command center for the Infinity System. 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 Infinity Control™ should be mounted:

•Approximately 5 feet (1.5 meters) from the floor.

•Close to or in a frequently used room, preferably on an inside partitioning wall.

•On a section of wall without pipes or duct work.

The Infinity Control™ should NOT be mounted:

•Close to a window, on an outside wall, or next to a door leading to the outside.

•Exposed to direct light or heat from a lamp, sun, fireplace, or other temperature-radiating objects which could cause a false reading.

•Close to or in direct airflow from supply registers.

•In areas with poor air circulation, such as behind a door or in an alcove.

REMOTE SENSOR OPTION — A remote room sensor can be used with the Infinity Control™ to take the place of the internal temperature sensor. This allows the 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 is wired to the terminal block connectors labeled S1 and S2. The Infinity Control™ will automatically detect the remote sensor and ignore its internal sensor. It is also important to note the humidity sensor cannot be remotely located, so do not locate the Infinity Control™ in an area where humidity sensing may not be accurate.

NOTE: S1 & S2 connection on UI back-plate is now used for the Remote Room Sensor, NOT for OAT Sensor hookup (S1 & S2 was previously used for OAT).

WIRING CONSIDERATIONS — Ordinary thermostat wire is recommended. Use 22 AWG or larger for normal wiring applications. Continuous wire lengths over 100 ft. 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 the installation.

Each device in the Infinity 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.

MOUNTING INFINITY CONTROL™ — There are two options

for mounting the Infinity Control™ to the wall. First, familiarize yourself with all plastic assembly pieces shown in Figs. 2 through 9. The User Interface will snap together with either the Recess Mount or the Surface Mount backplate.

RECESS MOUNT — This provides the thinnest mounting configuration (See Fig. 3). The backplate containing the recessed terminal block can be mounted directly to the wall by cutting a hole 1 ½″ wide by 2 1/8″ high. Mark location and cut hole in wall.

NOTE: Always ensure the Infinity Control™ location is acceptable before cutting any holes in wall.

SURFACE MOUNT — This provides surface mounting configuration, which allows use of a small hole in the wall. A surface mount backplate is supplied (See Fig. 4). Attach backplate as shown in figure 7, and the assembly will mount directly to the wall requiring only a small hole in the wall allowing a four wire connection to pass through.

NOTE: Once Infinity Control™ is secured to wall with the backplate assembly (snapped together), care must be taken not to bend or break the interlocking tabs when removing. Gently remove Infinity Control by rocking up/down until interlocking tabs release.

DECORATIVE BACKPLATE — Supplied, is a thin, decorative backplate (see Fig. 5), to hide any marks/screw holes left from the previous thermostat. This decorative backplate (or beauty ring) can be used in either the recess or surface mount installation by snapping it onto the back of the recessed mount backplate or surface mount backplate before securing to the wall. See Fig. 8 and 9 for a larger decorative backplate (5.75″ wide X 6″ tall), which can be ordered separately.

c. Discard or recycle old thermostat.

NOTE: Mercury is a hazardous waste and MUST be disposed of properly.

3.Select Infinity Control™ mounting plastic (recess mount or surface mount and decorative backplate if desired).

4.Route wires through large hole in mounting plastic. Level rear plastic against wall (for aesthetic value only - Infinity Control™ need not be level to operate properly) and mark wall through two mounting holes.

5.Drill two 3/16 inch mounting holes in wall where marked.

6.Secure mounting plastic to wall using two screws and anchors provided.

7.Adjust length and routing of each wire to reach each wire entry on the connector backplate. Strip ¼ inch of insulation from each wire.

ELECTRICAL OPERATION HAZARD

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

Improper wiring of the ABCD connector will cause the Infinity Control™ 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 Infinity 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. humidifier, ventilator, UV lights, etc.)

12.Turn on power to equipment.

EQUIPMENT WIRING DIAGRAMS:

See wiring diagram Figs. 12, 13 and 14.

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

See wiring diagram figure 12 for a Typical Four-Wire Connection Diagram, which includes an Infinity indoor communicating furnace or FE fan coil with a 2-speed Puron® communicating outdoor unit. No additional OAT (outdoor air temperature) sensor is required because the Infinity Control will use the temperature sensor inside the 2-speed unit.

See wiring diagram figure 13 for a Typical Connection Diagram, which includes an Infinity indoor communicating furnace or FE fan coil, with a 1-speed air conditioning unit (non-communicating outdoor). An Outdoor Air Temperature sensor may be installed (not required) at the indoor furnace or fan coil OAT terminals. When OAT is applied, the Infinity System will provide full system features and benefits.

See wiring diagram Fig. 14 for a Typical Connection Diagram for FE fan coil with a 1-speed heat pump (using non-communicating outdoor unit). When OAT is applied, the Infinity System will provide full system features and benenfits.

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 Infinity System control humidifier operation.

Bypass Humidifiers — A bypass humidifier should be wired directly to the furnace or fan coil HUM and 24vac COM terminals. The Infinity 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 Infinity 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.
