*To use Static Pressure Reset with a Comfort System AirManager, configure the variable name to SPRESET.

Currently, to make use of the static reset information, a cus- tom program must be written in a Comfort Controller to read the reset value and change the set point of the static pressure control in the air source. Use this configuration to create a vari- able name (Static Pressure Reset Value). See the application manual for information about creating this custom program.

The Comfort System AirManager™ control has an internal SPRESET variable which functions to accept the static pres- sure reset value from the linkage coordinator (refer to the Air Manager manual for configuration setup).

→CCN Linkage Data — A zone controller configured as a Linkage master has the ability to poll its slaves and collect the high, low or average value of any variable within its slaves. Once the high, low or average is determined, the master can then transfer that value to a configured bus number, element number and point name. Typically this feature is used to deter- mine a system’s highest indoor air quality reading.

In order to utilize this feature the CCN Variable Name being collected from the slaves must be supplied. The data transfer rate must be specified and whether the high, low, or average value is being determined. After the value has been deter- mined, a valid point name and CCN address to transfer the value to must be entered.

→Temp Sensor Grouping — Each ComfortID™ controller has the capability to broadcast the associated space temperature sensor’s data or listen to another controller’s sensor data over the network. All controllers sharing the same sensor must be installed on the same CCN bus.

There are three configuration decisions that must be config- ured in order to share sensors. The Temp Sensor Mode is used to specify if a controller will use its own local sensor, broadcast its local sensor, or listed to another controller’s sensor broad- cast. The Temp Sensor Config is used to specify if the control- ler is sharging the space temperature information only or the space temperature and temperature offset slidebar information. The Broadcast Device ID decision is used to specify which controller number a zone will listen for when configured to receive another controller’s broadcast.

	Range	1	= Local Sensor,
		2	= Broadcast, 3 = Listen

OCCUPANCY CONFIGURATION SCREEN — The Oc- cupancy Configuration screen is used to set the occupied schedule. See Table 7.

Manual Override Hours — The Manual Override Hours deci- sion is used to command a timed override by entering the num- ber of hours the override will be in effect.

If the occupancy schedule is occupied when this number is downloaded, the current occupancy period will be extended by the number of hours downloaded.

If the current occupancy period is unoccupied when the oc- cupancy override is initiated, the mode will change to occupied for the duration of the number of hours downloaded.

If the occupancy override will end after the start of the next occupancy period, the mode will transition from occupancy override to occupied without becoming unoccupied, and the occupancy override timer will be reset.

An active occupancy override or a pending occupancy over- ride may be canceled by downloading a zero to this configura- tion. Once a number other than zero has been downloaded to this configuration any subsequent downloads of any value oth- er than zero will be ignored by the zone controller.

	Range	0 to 4
	Default Value	0

Occupancy Scheduling — For flexibility of scheduling, the occupancy programming is broken into eight separate periods. For each period the scheduling, the active days of the week, occupied start time, and occupied stop time needs to be configured.

Day of Week — This configuration consists of eight fields corresponding to the seven days of the week and a holiday field in the following order: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday, Holiday. A separate con- figuration screen is used.
