48TC
T55/56 Override Duration
This sets the occupancy override duration when the override button is pushed on the space sensor.
Factory Default = 1 hr Range =
IAQ Low Reference @ 4mA
This is used when an IAQ sensor is installed on Input 1 or
2.This value is displayed and used when 4mA is seen at the input.
Factory Default = 0 PPM
Range =
IAQ High Reference @ 20mA
This is used when an IAQ sensor is installed on Input 1 or
2.This value is displayed and used when 20mA is seen at the input.
Factory Default = 2000 PPM Range =
NOTE: IAQ low Reference @ 4mA and IAQ High Reference @ 20mA are used to set the linear curve of mA vs. PPM.
OAQ Low Reference @ 4mA
This is used when an OAQ sensor is installed on Input 1 or 2. This value is displayed and used when 4mA is seen at the input.
Factory Default = 0 PPM Range =
OAQ High Reference @ 20mA
This is used when an OAQ sensor is installed on Input 1 or 2. This value is displayed and used when 20mA is seen at the input.
Factory Default = 2000 PPM Range =
NOTE: OAQ low Reference @ 4mA and OAQ High Reference @ 20mA are used to set the linear curve of mA vs. PPM.
Economizer
Economizer Exists
This point tells the controller if there is an economizer installed on the unit.
Factory Default = NO if no economizer YES if there is an economizer installed
Economizer Minimum Position
This defines the lowest economizer position when the indoor fan is running and the building is occupied.
Factory Default = 20% Range =
Economizer High OAT Lockout
If the outdoor air temperature rises above this value, economizer cooling will be disabled and dampers will return and stay at minimum position.
Factory Default = 75_F Range =
Power Exhaust Setpt
When the economizer damper position opens above this point the power exhaust operation will begin. When the damper position falls 10% below the setpoint, the power exhaust will shutdown.
Factory Default = 50% Range =
NOTE: This point is only used when Continuous Occ Exhaust = NO
Continuous Occ Exhaust
This point tells the controller when to run the power exhaust if equipped on the unit. If set to YES, the power exhaust will be on all the time when in occupied mode and will be off when in unoccupied mode. If set to NO the power exhaust will be controlled by the Power Exhaust Setpoint.
Factory Default = NO
IAQ
Max Differential CO2 Setpt
If the difference between indoor an outdoor air quality becomes greater then this value the damper position will stay at the IAQ Greatest Min Dmpr Pos. configuration point
Factory Default = 650 PPM Range =
IAQ Greatest Min Dmpr Pos.
This is the greatest minimum position the economizer will open to while trying to control the indoor air quality, CO2 differential.
Factory Default = 50% open Range =
Clockset
This submenu screen allows you to set the date and time manually. The Daylight Savings Time (DST) can also be changed here. The date and time is automatically set when ever software is downloaded. The clock is a 24 hour clock and not am/pm. The time should be verified (and maybe changed) according to unit location and time zone.
Factory Default = Eastern Standard Time
USERPW
This submenu screen allows you to change the user password to a four number password of choice. The User password change screen is only accessible with the Administrator Password (1111). The ADMIN password will always override the user password.
