2INTRODUCTIONThe Infinity Zone System consists of several intelligentcommunicating components which includes the Infinity ZoneControl (or User Interface), Smart Sensors, Damper ControlModule, variable speed furnace or FE fan coil, 2--stage AC or HPand Infinity Packaged Products, which continually communicatewith each other via a four--wire connection called the ABCD bus.Commands, operating conditions, and other data are passedcontinually between components over the ABCD bus. The result isa new level of comfort, versatility, and simplicity.All Infinity furnaces or fan coils are variable--speed andmulti--stage for maximum flexibility, efficiency, and comfort. Theysupport controlled ventilation, humidification, dehumidification,and air quality control. Either an Infinity 2--stage (communicating),or a standard 24VAC controlled outdoor unit may be used.When using conventional outdoor units, the Infinity furnace or fancoil provides the 24 volt signals needed to control them. Also, theInfinity Damper Control Module (P/N SYSTXCC4ZC01) allowsconnection of a Carrier HRV or ERV without the need for aseparate wall control.All system components are controlled through the wall mountedInfinity Zone Control, which replaces the conventional thermostatand provides the homeowner with a single wall control for allfeatures of the system.Design ConsiderationsThe Infinity Zone system is unique because a bypass damper mustnot be used. This is possible due to the intelligence of the systemand variable speed motor technology. For trouble--freeapplications, the following parameters should always be met:1. Zones should be sized so that each zone can deliver at leastthe minimum airflow for the system in both heating andcooling modes.2. Oversize duct work by 25% to avoid excess noise at mini-mum zone airflow.3. Be aware that heating airflow may be higher than coolingairflow depending on equipment combination.INSTALLATION AND START--UPOVERVIEWThis instruction covers installation of the Infinity Zone Controlonly. Physical installation instructions for the indoor and outdoorequipment, Damper Control Module, and accessories are providedwith each unit.Setup, commissioning, operation, and troubleshooting of theInfinity Zone System are covered in this installation instruction. Itis the guide to connecting the system components andcommissioning the system once all physical components areinstalled. Special screen prompts and start--up capabilities areprovided in the Infinity System to simplify and automate the initialcommissioning of the system.S Install Infinity Zone Control according to this instruction.S Install indoor unit, outdoor unit, and accessories according totheir instructions.S Wire complete system according to this instruction.S Setup, commission, and operate system according to thisinstruction to assure a smooth and trouble free start--up.INSTALLATIONCheck Equipment and Job SiteInspect equipment. File claim with shipping company prior toinstallation if shipment is damaged or incomplete.Infinity Zone Control Location and WiringConsiderationsELECTRICAL OPERATION HAZARDFailure to follow this warning could result in personal injuryor death.Disconnect power before routing control wiring.! WARNINGAll wiring must comply with national, local, and state codes.Infinity Zone Control LocationThe Infinity Zone Control User Interface is the command center forthe Infinity Zone System and is typically located in Zone 1 to senseand control temperature in this zone. It should be located where itis easily accessible and visible to the adult homeowner or end user.For accurate temperature measurement, the following guidelinesshould be followed:The Infinity Zone Control and Room Sensors should be mounted:S Approximately 5 feet (1.5 meters) from the floor.S Close to or in a frequently used room, preferably on an insidepartitioning wall.S On a section of wall without pipes or ductwork.The Infinity Zone Control and Room Sensors should NOT bemounted:S Close to a window, on an outside wall, or next to a door leadingto the outside.S Exposed to direct light or heat from a lamp, sun, fireplace, orother temperature--radiating objects which could cause a falsereading.S Close to or in direct airflow from supply registers.S In areas with poor air circulation, such as behind a door or in analcove.Remote Room Sensor OptionA Remote Room Sensor can be used with the Infinity ZoneControl to take the place of the User Interface internal temperaturesensor. This allows the Infinity Zone Control to be mounted inareas with less than optimal airflow (such as near an exterior door,window or in a closet). The remote sensor can be wired to theterminal block connectors labeled S1 and S2 at the User Interfacebackplate, or the OS1 and OS1C connection at the Damper ControlModule. In either case, the Infinity Zone Control will automaticallydetect the Remote Room Sensor and ignore its internal temperaturesensor. It is also important to note the humidity sensor cannot beremotely located, so do not locate the Infinity Zone Control in anarea where humidity sensing may not be accurate.NOTE: S1 & S2 connection on User Interface backplate is nowused for Remote Room Sensor, NOT for OAT Sensor hookup.In addition, the Remote Room Sensor is a temperature sensor only,having no additional user inputs. This sensor is typically connectedto the Damper Control Module and used to sense and controltemperature in each zone.Remote Sensor AveragingTypically, one Remote Room Sensor is used per zone, but multiplesensors may be used and averaged in some applications. Averagingrequires a special series--parallel wiring method with a specificnumber of sensors. See Fig. 2 in this manual for wiring diagram.CCUIZ01-- B
