37 6.3.6.2. Zone Offsets This option allows actual temperature offset for each zone, allowing calibration (or deliberate miscalibration) of each sensor. Use the Left () buttons to change the zone. After the selection is made, touchSAVE. STemperature Offset:Adjustable between --5 to 5_F(--3to3_C) dDefault = 0_F 6.3.6.3. Zone Airflow Limits Since a bypass damper is prohibited in this system, this setting is used to select the maximum allowable noise/airflow relationship into each zone based on air noise and comfort requirements.LOWmeans 100% of maximum assessed airflow; MED-- LOWmeans 138% of maximum assessed airflow;MEDIUMmeans 176% of maximum assessed airflow;MED-- HIGHmeans 214% of maximum assessed airflow;HIGHmeans 250% of maximum assessed airflow; andNO LIMITmeans the equipment does not stage down. CFM associated for each limit is shown on the screen. Compare this value with the equipment’s low stage CFM value to ensure that equipment will run for each zone. Assessed airflow is determined as described inDUCT ASSESSMENT. After the selections are made, touchSAVE. STouch the zone name that you wish to change SSelect the zone to adjust airflow:Low, Med --Low, Medium, Med --High, High, or No Limit dDefault = High 6.3.6.4.
