REMOTE CONTACT CONFIG — The remote timeclock

contact input 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

Damper Service Configuration Table — The Damp-

er Service Configuration Table (DAMPER) contains decisions

used to configure the damper minimum, maximum and

ventilation positions. See Table 7.

COOL MINIMUM POSITION — This configuration is the

minimum damper position the terminal will control to when

the equipment mode is Cooling (or Fan Only), or free cooling

and the space requirements for cooling are at a minimum.

Cool Minimum

Position: Units %

Range 0 to 100

Default Value 0

COOL MAXIMUM POSITION — This configuration is the

maximum damper position the terminal will control to when

the equipment mode is cooling (or fan only), or free cooling

and the space requirements for cooling are at a maximum.

Cool Maximum

Position: Units %

Range 0 to 100

Default Value 100

REHEAT MINIMUM POSITION — This configuration is

for single duct units with ducted reheat. Configure the desired

damper position at which the reheat will provide optimum

performance. This value is compared to the Minimum Cool

value and the greater of the two values is used to determine the

damper position.

Reheat Minimum

Position: Units %

Range 0 to 100

Default Value 0

HEAT MINIMUM POSITION — This configuration is the

Minimum damper position the terminal will control to when

the equipment mode is Warm-Up or Heat. If the terminal is not

configured for VAV central heating this is the only position the

terminal will control to for these equipment modes.

Heat Minimum

Position: Units %

Range 0 to 100

Default Value 0

HEAT MAXIMUM POSITION — This configuration is used

to configure the maximum damper position at which the zone

controller will operate if VAV central heat is configured to yes.

If the equipment mode is Heat or Warm-Up and the demand in

the space is for heat the zone controller will calculate the

proper damper position needed to achieve space temperature

set point, operating between the Heat Min and Heat Max.

Heat Maximum

Position: Units %

Range 0 to 100

Default Value 100

VENTILATION POSITION — This configuration is used to

specify the ventilation damper position the terminal will con-

trol to when the air source operating mode is VENT.

Ventilation

Position: Units %

Range 0 to 100

Default Value 30

Holiday Configuration Table — The Holiday Con-

figuration Table (HOLDYxxS) contains decisions used to con-

figure the start date and duration of holidays. See Table 8.

START MONTH — The start month is the month in which

the holiday starts. Months are represented by numbers with 1

representing January, 2 February, up to 12.

Start Month: Range 1 to 12

Default Value 1

START DAY — The start day is the day on which the holiday

will start.

StartDay: Range 1to31

Default Value 1

DURATION — Length of time, in days, that the holiday will

last.

Duration: Range 0 to 365

Default Value 0

Linkage Configuration Table — The Linkage Con-

figuration Table (LINKAGE) contains decisions used to

configure the linkage coordinator zone controller's linkage

settings. This is where the linkage coordinator zone controller,

the air source and the bypass controller options are configured.

It also includes Carrier Network Function Configuration used

for collecting data from multiple controllers and finding the

high, low or average value and transferring the data to another

controller. This table is also used to setup Temperature Sensor

Grouping, which is the sharing of one space temperature sensor

among multiple zone controllers. See Table 9.

LINKAGE MASTER ZONE — This decision defines if the

zone controller will function as a Linkage Coordinator

(Linkage Master) for itself and other zones.

If the zone controller is to use a supply air sensor for

stand-alone operation, this configuration must be configured to

No and the number of Zones to 1.

If the zone controller will use its primary air sensor to deter-

mine the air handler mode for a number of zone controllers,

configure this configuration to Yes, input the number of zones,

and leave the air source decisions at the default values of zero.

If this zone controller will communicate linkage informa-

tion with an air source, configure this configuration to Yes. The

number of zones must be configured and the address of the air

source entered.

Linkage

Master Zone: Range Yes/No

Default Value No

NUMBER OF ZONES — This decision defines the number of

zone controllers (including itself) for the Linkage Coordinator to

scan and include as part of the average temperature, set points,

and occupancy information to the air source. The address of the

zone controller functioning as a Linkage Coordinator must be

larger than the number of zones configured. The zone controller

will scan addresses less than its own, including information for

as many zones as are configured. Other zone controller config-

ured as linkage coordinators will also be included, so it is possi-

ble to have zones scanned by more than one linkage coordinator.

Therefore care must be taken in addressing to prevent overlap-

ping systems, unless overlapping systems is necessary. In large

buildings the use of bridges and multiple busses is recommended

to improve communication and provide system differentiation.

Number of

Zones: Range 1 to 32

Default Value 1

1 2 ... 56 57 58 59 60 61 62 63 64 65 66 ... 315 316
