Fan Off Delay

— The Fan Off Delay configuration is used to

define a delay time. The delay time is from when the heat is de-

activated (in a parallel terminal) until the parallel fan is deacti-

vated. This allows the fan to circulate air and remove the resid-

ual heat from the heat source.

Fan Off Delay: Units minutes

Range 1 to 15

Default Value 2

Two-Position Heat Logic

— This configuration is used for

controlling a normally closed or normally open valve for hot

water. Use normal logic if the valve is normally closed. Use in-

verted logic if the valve is normally open.

Two Position

Heat Logic: Range Normal/Invert

Default Value Normal

Space Temperature Trim

— This configuration is used to trim

a space sensor which might need calibration. For example, if

the temperature displayed is two degrees above the value mea-

sured with calibrated test equipment, input a value of –2.0.

Space Temperature

Trim: Units delta F (delta C)

Range –9.9 to 9.9

Default Value 0.0

Supply Air Temperature Trim

— This configuration is used

to trim a supply air sensor which might need calibration. For

example, if the temperature displayed is two degrees above the

value measured with calibrated test equipment, input a value of

–2.0.

Supply Air Temperature

Trim: Units delta F (delta C)

Range –9.9 to 9.9

Default Value 0.0

Remote Contact Config

— The remote timeclock contact in-

put can be configured as a normally open or normally closed

contact. When the timeclock input is ‘On’ the zone will follow

it’s local occupancy schedule. When the timeclock input is

‘Off’ the zone will be forced into unoccupied state.

Remote Contact

Config: Range Close/Open

Default Value Close

OPTIONS SERVICE CONFIGURATION SCREEN —

The Options Service Configuration screen is used to configure

the service options of the air terminal controller. See Table 11.

Occupancy Schedule Number

— The Occupancy Schedule

Number defines what Occupancy schedule the zone controller

will use. Occupancy Schedule 64 is a local schedule. Occupan-

cy Schedules 65 to 99 are global schedules.

Occupancy Schedule

Number: Range 64 to 99

Default Value 64

Global Schedule Master

— The Global Schedule Master con-

figuration allows the Occupancy Schedule to be used as a Glo-

bal Schedule Master (Occupancy Schedules 65-99).

Global Schedule

Master: Range No/Yes

Default Value No

Override

— The Override parameter is used to configure the

number of hours and minutes the override will be in effect. The

user initiates override by pressing the override button on the

space temperature sensor. This will cause the schedule to enter

into the Occupied mode. If global scheduling is used, all zones

using the global schedule will enter Occupied mode. Pushing

the override button during Occupied mode will have no effect.

If the occupancy override is due to end after the start of the

next occupancy period, the mode will transition from occupan-

cy override to occupied without becoming unoccupied, and the

occupancy override timer will be reset.

NOTE: If using the tenant billing function, the override

hours set point must be configured between 1 and 3 hours.

Override: Units Hours: Minutes

Range 00:00 to 24:00

Default Value 00:00

Broadcast Acknowledger

— This configuration defines if the

zone controller will be used to acknowledge broadcast messag-

es on the CCN bus. One broadcast acknowledger is required

per bus, including secondary busses created by the use of a

bridge.

Broadcast

Acknowledger: Range No/Yes

Default Value No
