Scheduling

Scheduling is used to start heating or cooling (become occupied) based upon a day of week and a time period and control to the occupied heating or cooling setpoints. Scheduling functions are located under occupancy determination and the schedule menu accessed by the Menu softkey (see Appendix - for menu structure). Your local time and date should be set for these functions to operate properly. Five scheduling functions are available by changing the Occupancy Source to one of the following selections:

Always Occupied (Default Occupancy)

The unit will run continuously. RTU-MP ships from the factory with this setting.

Local Schedule

The unit will operate according to the schedule configured and stored in the unit. The local schedule is made up of three hierarchy levels that consist of two Override schedules, twelve Holiday and four Daily schedules, and are only accessible by the BACview screen (handheld or virtual).

The Daily schedule is the lowest schedule in the hierarchy and is overridden by both the Holiday and Override schedule. It consists of a start time, a stop time (both in 24 hour mode) and the seven days of the week, starting with Monday and ending in Sunday. To select a daily schedule scroll to the Schedules menu off of the Menu selection. Enter the User password and change the Occupancy Source to Local Schedule. Scroll down and over to the Daily menu and press enter. Choose one of the four Daily schedules by pressing the Next softkey and change the Use? point from NO to YES by selecting the point and pressing the INCR or DECR softkey. Press the OK softkey and scroll to the start and stop times. Edit these times following the same steps as the Use? point. Finally scroll down to the Days: section and highlight the days required for the Daily schedule by INCR or DECR softkeys and press OK softkey.

The Holiday schedule is created to override the Daily schedule and identify a specific day and month of the year to start and stop the unit and change control to the unoccupied heating and cooling setpoints. Follow the same steps to turn on one of the twelve Holiday schedules and start and stop times. Next, select one out of the twelve months and one out of the thirty-one days of that month. The RTU-MP will now ignore the Daily schedule for the specific day and time you selected and follow the Holiday Schedule for this period.

The Override schedules primary purpose is to provide a temporary change in the occupied heating and cooling setpoints and force the unit to control to the unoccupied heating and cooling setpoints. This would occur on a set day in a particular month and last during the start and stop time configured. The Override schedule is enabled by following the same steps to create the Holiday schedule.

NOTE: Push button override is only available when running a local or BACnet Schedule.

BACnet Schedule

For use with a Building Automation System that supports native BACnet scheduling is scheduling the unit. With the Occupancy Source set to BACnet schedule the BAS will control the unit through network communication and it’s own scheduling function.

BAS On/Off

The Building Automation System is scheduling the unit via an On/Off command to the BAS ON/OFF software point. The Building Automation System can be speaking BACnet, Modbus, or N2 and is writing to the BAS On/Off point in the open protocol point map.

NOTE: If the BAS supports NATIVE BACnet scheduling, then set the Occupancy Source to BACnet schedule. If the BAS is BACnet but does NOT support NATIVE BACnet scheduling, then set the Occupancy Source to BAS On/Off.

DI On/Off

Ahard-wired input on the RTU-MP will command the unit to start/stop. Inputs 3, 5, 8, and 9 on plug J5 can be hard-wired to command the unit to start/stop.

NOTE: Scheduling can either be controlled via the unit or the BAS, but NOT both.

Indoor Fan

The indoor fan will be turned on whenever any one of the following conditions is true:

SIt is in the occupied mode. This will be determined by its own internal occupancy schedule.

SWhenever there is a demand for cooling or heating in the unoccupied mode.

S Whenever the remote occupancy switch is closed during DI On/Off schedule type or if occupancy is forced occupied by the BAS during BAS On/Off schedule type.

When transitioning from unoccupied to occupied, there will be a configured time delay of 5 to 600 seconds before starting the fan. The fan will continue to run as long as compressors, heating stages, or the dehumidification relays are on when transitioning from occupied to unoccupied with the exception of Shutdown mode. If Fire Shutdown, safety chain, SAT alarm or SPT alarm are active; the fan will be shutdown immediately regardless of the occupancy state or demand.

The RTU-MP has an optional Supply Fan Status input to provide proof of airflow. If this is enabled, the point will look for a contact closure whenever the Supply Fan Relay is on. If it is not enabled then it will always be the same state as the Supply Fan Relay. The cooling, economizer, heating, dehumidification, CO2 and power exhaust routines will use this input point for fan status.
