CONFIGURATION PARAMETERS

Using the ZM7601 or ZM7603 Configuration Tool Software, it is possible to program variables that affect control of the

variable air volume system. The variables that may be programmed and a brief description are listed below.

Recommended

Variable Name

Variable Label

Functional Description/Program Options

Value

Number of Fan Stages

FAN_STG

Only one fan stage is available.

1

Type of Supply and

FAN_TYPE

VAV fan actuator type.

Return Fans

0 = Modulating fan control of inlet vanes

or variable speed drive.

1 = Floating fan control.
2 = Velocity pressure control (2-speed fan).

Fan Motor Speed

FAN_MOTOR_SPEED

Programmable duration, in number of
seconds, for full motor travel from 0-100%.
Range = 30-160 seconds programmed to
specified motor speed; i.e., 60.
Default = 100 seconds.

Supply Fan Start Delay

FANSTART_DELAY

Prevents fan start-up after power-up or reset

60-90

condition. Valid if VN_CSD is not configured.

seconds

Value should equal number of seconds for full
supply fan motor travel. One second accuracy,
0-255 seconds.

Type of Cooling

COOL_TYPE

Programmable:

Equipment

0 = Staged cooling.
1 = Stages plus floating.
2 = 1 stage plus modulating cooling valve.

Number of Cool Stages

COOL_STG

Programmable cool stages 0-12 (total
compressors and unloaders).

Cooling Modulation

MOD_COOL_DELAY

Time delay between cooling on/off stages

30 seconds

Delay

and cooling modulation. Fifteen second
accuracy, 0-180 seconds.

Cool Motor Speed

COOL_MOTOR_SPEED

Programmable duration, in number of
seconds,  for full motor travel from 0-100%.
Range = 30-160 seconds, programmed to
specified motor speed; i.e., 60.
Default = 100 seconds.

Compressor Number

COMP_NUM[ ]

Compressor/unloader array for configuration

Array

of cooling equipment. Compressors =
1, 2, 3, 4 and unloaders = 0; for example,
array: 6 stages, 2 compressors, 2 unloaders
per compressor programmed as:

Comp_Num [1] = 1
Comp_Num [2] = 0
Comp_Num [3] = 0
Comp_Num [4] = 2
Comp_Num [5] = 0
Comp_Num [6] = 0

Compressor Minimum

COOL_TIME

Value used for minimum on and off time

240 seconds

Time

with each compressor stage and for interstage
time delay. Fifteen second accuracy, 0-3780
seconds.

Unloader Minimum

UNLOAD_TIME

Value used for minimum on and off time

120 seconds

Time

with each unloader stage and for interstage
time delay. Fifteen second accuracy, 0-3780
seconds.
