NOTE: On standard units, the fire shutdown input is the terminals Fire Shutdown 1 and 2. On
Outdoor Enthalpy
If an Outdoor Enthalpy accessory was field installed, the unit must be configured for it by setting Configuration→ECON→EN.SW, identifies the normally open or normally closed status of this input when the outdoor enthalpy is low.
IAQ Switch
If an IAQ Switch accessory was field installed, the unit must be configured for it by setting Configuration→AIR.Q→II.CF, identifies the normally open or normally closed status of this input when the indoor air quality value is low (good) and also selects the unit response to this input.
NOTE: An IAQ switch cannot be used if an enthalpy switch is already on this input.
IAQ Sensor
If an CO2 Sensor accessory was field installed, the unit must be configured for it by setting Configuration→AIR.Q→IA.CF selects the unit response to this input. Default conversion to 0 to 2000 ppm.
OAQ Sensor
If an Outdoor Air Quality Sensor accessory was field installed, the unit must be configured for it by setting Configuration→AIR.Q →OA.CF selects the unit response to this input. Default conversion to 0 to 2000 ppm.
Fan Status
If a Fan Status accessory was field installed, the unit must be configured for it by setting Configuration→UNIT→FN.SW to normally open (1) or normally closed (2). Normally open (1) is the preferred configuration.
NOTE: Fan Status input is not on the terminals marked Fan Status.
Filter Status
If a Filter Status accessory was field installed, the unit must be configured for it by setting Configuration→UNIT→FL.SW to normally open (1) or normally closed (2). Normally open (1) is the preferred configuration.
Programming Operating Schedules
The ComfortLinkt controls will accommodate up to eight different schedules (Periods 1 through 8), and each schedule is assigned to the desired days of the week. Each schedule includes an occupied on and off time. As an example, to set an occupied schedule for 8 AM to 5 PM for Monday through Friday, the user would set days Monday through Friday to ON for Period 1. Then the user would configure the Period 1 Occupied From point to 08:00 and the Period 1 Occupied To point to 17:00. To create a different weekend schedule, the user would use Period 2 and set days Saturday and Sunday to ON with the desired Occupied On and Off times.
NOTE: By default, the time schedule periods are programmed for 24 hours of occupied operation.
To create a schedule, perform the following procedure:
1.Scroll to the Configuration mode, and select CCN
CONFIGURATION (CCN). Scroll down to the Schedule Number (Configuration→CCN→SCH.O=SCH.N). If password protection has been enabled, the user will be prompted to enter the password before any new data is accepted. SCH.N has a range of 0 to 99. The default value is 1. A value of 0 is always occupied, and the unit will control to its occupied set points. A value of 1 means the unit will follow a local schedule, and a value of 65 to 99 means it will follow a CCN schedule. Schedules 2−64 are not used as the control only supports one internal/local schedule. If one of the 2−64 schedules is configured, then the control will force the number back to 1. Make sure the value is set to 1 to use a local schedule.
2.Enter the Time Clock mode. Scroll down to the LOCAL TIME SCHEDULE (SCH.L) sub−mode, and press ENTER. Period 1 (PER.1) will be displayed.
3.Scroll down to the MON.1 point. This point indicates if schedule 1 applies to Monday. Use the ENTER command to go into Edit mode, and use the Up or Down key to change the display to YES or NO. Scroll down through the rest of the days and apply schedule 1 where desired. The schedule can also be applied to a holiday.
4.Configure the beginning of the occupied time period for Period 1 (OCC). Press ENTER to go into Edit mode, and the first two digits of the 00.00 will start flashing. Use the Up or Down key to display the correct value for hours, in 24−hour (military) time. Press ENTER and hour value is saved and the minutes digits will start flashing. Use the same procedure to display and save the desired minutes value.
5.Configure the unoccupied time for period 1 (UNC). Press ENTER to go into Edit mode, and the first two digits of the 00.00 will start flashing. Use the Up or Down key to display the correct value for hours, in 24−hour (military) time. Press ENTER and hour value is saved and the minutes digits will start flashing. Use the same procedure to display and save the desired minutes value.
6.The first schedule is now complete. If a second schedule is needed, such as for weekends or holidays, scroll down and repeat the entire procedure for period 2 (PER.2). If additional schedules are needed, repeat the process for as many as are needed. Eight schedules are provided. See Table 3 for an example of setting the schedule.
