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. HEAT HOLD COOL OFF 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. Infinity Control™ SYSTXCCUID01 A03149 NOTE: Read the entire instruction manual before starting the installation. This symbol → indicates a change since the last issue.

Follow all local electrical codes during installation. All wiring must conform to local and national electrical codes. 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. 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. Special screen prompts and start-up capabilities are provided in the Infinity System to simplify and lead you through the initial commissioning of the system. So: • • • • Install the Infinity Control™ according to this instruction. Install the indoor unit, outdoor unit, and accessories according to their instructions. Wire the complete system according to this instruction. Setup, commission, and operate the system according to this instruction to assure yourself a smooth and trouble free start-up. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

INSTALLATION STEP 1 — CHECK EQUIPMENT AND JOB SITE It is not mandatory that the above color code be used, but each ABCD connector in the system MUST be wired consistently. INSPECT EQUIPMENT — File claim with shipping company, prior to installation, if shipment is damaged or incomplete. 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. STEP 2 — INFINITY CONTROL™ LOCATION AND WIRING CONSIDERATIONS 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. ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury or possible equipment damage. Disconnect Power before routing control wiring. NOTE: Always ensure the Infinity Control™ location is acceptable before cutting any holes in wall. All wiring must comply with national, local, and state codes. 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. 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: 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. 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: 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. • 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). A03185 Fig. 2—Infinity Control™ 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. STEP 3 — INSTALLING INFINITY CONTROL™ ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury or death. Before installing Infinity Control™, turn off all power to equipment. There may be more than one power source to disconnect. 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: 1. Turn off all power to equipment. A — Green = Data A B — Yellow = Data B C — White = 24VAC (Com) D — Red = 24VAC (Hot) 2. If an existing thermostat is being replaced: a. Remove existing thermostat from wall. b. Disconnect wires from existing thermostat. 2 Recessed terminal block in wall 11/2˝ wide by 2 1/8˝ high Recessed Mount Interlocking Tabs (4) A03186 A03190 Fig. 3—Recessed Mount Backplate Fig. 6—Recessed Mount Assembly Surface Mount Backplate to wall Interlocking Tabs (4) A03187 Fig. 4—Surface Mount Backplate A03191 Fig. 7—Surface Mount Assembly A04017 Fig. 5—Thin Decorative Backplate A03188 Fig. 8—Large Decorative Backplate c. Discard or recycle old thermostat. 8. Match and connect thermostat wires to proper terminals on User Interface backplate. See wiring diagram figures 12, 13 and 14. A — Green = Data A B — Yellow = Data B C — White = 24VAC (Com) D — Red = 24VAC (Hot) NOTE: It is not mandatory that the above color code be used, but each ABCD connection in the system MUST be wired consistently. A separate ABCD Connector comes inside packaging and should be used when connecting to the furnace (or fan coil). (See Fig. 10) NOTE: Insert connector properly into circuit board. 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. 3 Humidity/OAT Button Fan Button Display Screen (LCD) Left-Side Button Right-Side Button Time (+/-) Button HEAT Hold Button HOLD Heat Button Cool Button COOL Temperature (+/-) Button SCROLL SCHEDULE VACATION BASIC Schedule & Vacation Program Buttons PROGRAM A03192 System On/Off Button Basic & Advanced Setup Buttons ADVANCED SETUPS Up/Down Scroll Buttons Fig. 9—Decorative Backplate Assembly Schedule Vacation to program to start/end temperature vacation schedule Basic to set time, humidity Advanced for all other settings Flip Down Door Scroll up & down A B C D A03194 A03193 Fig. 11—Functional Overview Fig. 10—4–Wire ABCD Connector Variable-Speed Furnace/ Fan Coil ELECTRICAL OPERATION HAZARD Failure to follow this caution will result in equipment damage or improper operation.

Fig. 12—Universal Four-Wire Connection Diagram EQUIPMENT WIRING DIAGRAMS: See wiring diagram Figs. 12, 13 and 14. A03146 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. 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. 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. 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. 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. 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. 4 Variable-Speed Furnace/Fan Coil typical example for a communicating Variable-Speed Furnace / Fan Coil with a 2-spd.

Service = RUN / FAULT HISTORY Equipment Cycle Timer (adjustable 4-6 cycles per hour) This timer prevents the start of a heating or cooling cycle until 15 (or 10) minutes after the last start of the same cycle. Its function is to assure that the equipment is not cycled more than the selected times per hour. This timer is adjustable from 4 to 6 cycles per hour. This timer is defeated for one cycle when the desired temperature is manually changed. It can also be defeated for one cycle by simultaneously pressing the Fan and Temp + buttons. The indoor unit and outdoor unit (if communicating) has the following histories: NOTE: For Critical Fault Screens, see Trouble Shooting section in this document. Ten-Minute Staging Timer Resettable Faults: In multistage heating or cooling, this timer prevents any higher stage from turning on until the preceding stage has been on for 10 minutes. This timer is defeated if temperature error is greater than 5°F (usually due to a large change in desired temperature). • Fault counters for each piece of equipment that can be reset. Cycle Counters: • Number of heat/cool/power cycles the unit has performed. Run Times: Three-Minute Minimum On Time In normal operation, when a stage turns on, it will remain on for a minimum of three minutes. If the set point is changed, this timer is automatically cancelled, allowing the equipment to turn off immediately when the demand is removed. • Lifetime hours of operation in heating, cooling, and how long the unit has been powered. Service = TODAY’S DATE • This menu item allows the installer to enter the current date. It is used for time/date stamping of system faults. This should be entered every time prior to viewing ″LAST 10 SYSTEM FAULTS″ section. Service = MODEL / SERIAL NUMBERS Heat/Cool Set points (Desired Temperatures) A minimum difference of 2° (default) is enforced between heating and cooling desired temperatures. This is done by allowing one setting to ″push″ the other to maintain this difference. This difference is adjustable via the Install/Service menu under Thermostat Setup. • If available, this menu item allows the installer to view the model number and serial number of all communicating pieces of equipment in the system. Service = SERVICE PHONE NUMBER Auto Changeover This menu item allows the installer to enter a name and phone number that the homeowner can call for future service of the system. This name and phone number will appear to the homeowner whenever a service reminder pop-up message is displayed (i.e. Change Filter, etc.) When Auto mode is enabled (factory default) a change from heat to cool (or vice versa) will not occur until an opposite mode demand has existed for 30 minutes. If the set point is changed, the 30-minute requirement is defeated. This Auto Changeover time is adjustable via the Install/Service menu under Thermostat Setup. Range = 5 - 120 min. To edit: Smart Recovery 11 With Smart Recovery selected (factory default), transition out of setback begins a fixed time period before selected recovery time and gradually adjusts room temperature so desired temperature will be achieved at selected recovery time. The fixed time period is 1.5 hours. It operates in both heating and cooling. This only applies to programmable operation. The following errors will cause a Critical Malfunction screen to pop up.
