Info

The OVERRIDE key also allows access to the Installer Configuration Menu.See Configuring the TEC2647Z-2 or TEC2647Z-2+PIR Zone Controller onpage 15.• UP/DOWN arrow keys change the configuration parameters and activate asetpoint adjustment.Backlit LCDThe zone controller includes a two-line, eight-character backlit display. Low-levelbacklighting is present during normal operation and brightens when any userinterface key is pressed. The backlight returns to low level when the zonecontroller is left unattended for 45 seconds.Light-Emitting Diodes (LEDs)Two LEDs are included to show a call for heating or a call for cooling:• The HEAT LED is on when heating or reheat is on.• The COOL LED is on when cooling is on.Passive Infrared (PIR) Onboard Occupancy Sensor (TEC2647Z-2+PIR Model)The PIR onboard occupancy sensor allows for automatic switching between fullyadjustable occupied and standby temperature setpoints without user interaction.This feature results in incremental energy savings during scheduled occupiedperiods when the space is unoccupied.Status Display MenuThe Status Display Menu appears during normal zone controller operation. Thismenu continuously scrolls through the following parameters:• Room Temperature• Occupancy Status(Occupied/Unoccupied/Standby/Override)• Outside Temperature (Installation of an outside air temperature sensor allowsthe H lock and C lock parameters of the rooftop controller to discontinueheating or cooling operation in response to the outside air temperature. If anoutside air temperature sensor is not installed, an ambiguous outside airtemperature displays on the zone controller unless its MenuScro parameter isset to off.)Note: An option is available within the Installer Configuration Menu to lock outthe scrolling display and show only the Room Temperature parameter.PIR Onboard Occupancy Sensor Operation (TEC2647Z-2+PIR Model)The zone controller provides advanced occupancy logic when equipped with aPIR occupancy sensor cover or a remote PIR occupancy sensor attached to BI1.Note: Set the PIR Func parameter to on as described in Table 2 to enable thePIR occupancy sensing function.12TEC Zoning Control System for Stand-Alone and BACnet® MS/TP Networked ApplicationsTechnical Bulletin
The zone controller automatically switches occupancy levels from standby tooccupied as required, when local motion is sensed.Occupancy sensing is enabled only if a PIR occupancy sensor cover is installed onthe zone controller, or if a remote input is configured as a remote PIR occupancysensor (MotionNO or MotionNC) and the PIR Func parameter is set to on asdescribed in Table 2.PIR Diagnostic LEDsThe diagnostic LEDs within the zone controller brighten when motion is detectedwithin the first 30 minutes after the unit is powered up. The diagnostic LEDs donot light up or brighten after the initial 30-minute powerup period.Standby SetpointsThe standby setpoints have the same limitations and restrictions as the occupiedand unoccupied setpoints. The standby setpoints reside between the correspondingoccupied and unoccupied setpoint values.TEC2664Z-2 Rooftop Controller Operation OverviewBacklit, plain textLCD is easy to readin any condition.YESRoom Temp70.0ºFNOLEDs indicatesystem activity.Five keys on the rooftop controllermake operation easy and intuitive.Figure 3: Front Cover of Rooftop ControllerFIG:frnt_vw_rftp_cntrlrRooftop Controller User Interface KeysThe TEC2664Z-2 Rooftop Controller user interface consists of five keys on thefront cover (as illustrated in Figure 3). The function of each key is as follows:• Use the YES/SCROLL key to:- confirm display selections and to advance to the next display item- stop the Auto Scroll Display from automatically scrolling and to manuallyscroll to the next parameter on the displayNote: When the rooftop controller is left unattended for 45 seconds, therooftop controller display resumes scrolling.TEC Zoning Control System for Stand-Alone and BACnet® MS/TP Networked ApplicationsTechnical Bulletin13
