The default settings are shown in Table 12. Accessthe Installer Configuration Menu on the rooftop controller to reconfigure theparameters.To access the Installer Configuration Menu, press and hold the MENU key forapproximately 8 seconds. Once the Installer Configuration Menu begins, press theNO key to scroll through the parameters listed in Table 12. When the desiredparameter appears, use the YES key to choose the desired selection option. Pressthe YES key and then the NO key to continue scrolling through the parameters.When the rooftop controller is in the Installer Configuration Menu and leftunattended for approximately 8 seconds, the rooftop controller reverts to the AutoScroll Display.Configuring Input DI1N/ASet the analog reheat stageto the desired temperature.This setting can be differentthan the on/off reheat stagetemperature setting.Set the on/off reheat stageto the desired temperature.Set the on/off reheat stageto the desired temperature.This setting can be differentthan the analog reheat stagetemperature setting.When DI1 is configured for an alarm condition, an alarm condition appears locallywhen the input is closed. An alarm message is included on the Auto Scroll Display,and when the message appears, the backlight momentarily lights up.The DI1 input can be configured to the selection options included in Table 12.Table 12: TEC2664Z-2 Rooftop Controller Installer Configuration Menu (Part 1 of 5)ParameterAppearingon DisplayRTC MAC 1Description and DefaultSets a unique device address forthe rooftop controller on the MS/TPnetwork.Default: 4Note: This parameter setting mustbe the same as the RTCMAC parameter setting forall zone controllersassociated with this rooftopcontroller.Selection OptionsRange: 004 to 127Note: When setting the device address, press the UP/DOWN arrowkeys to change the device address in increments of 1; pressand hold the UP/DOWN arrow keys to change the deviceaddress in increments of 10.32TEC Zoning Control System for Stand-Alone and BACnet® MS/TP Networked ApplicationsTechnical Bulletin
