Sequencing

The zone concept is based on the idea to

obtain a homogeneous room climate within a

determined space by distributed generation

of conditioned air. Within a zone only one

room temperature exists, which is calculated

as the average value of all connected room

temperature sensors of the units in opera-

tion; this also applies to the room humidity,

1. Sequencing

Within a zone you can have a unit sequencing with change-over dependent on

time and failure.

The following parameters must be speciﬁed for this:

➊. Unit assignment

A zone is deﬁned by the assignment of units. A maximum of 32 zones can be

deﬁned with the adjustments from 1 to 32. Zone 0 means that the unit is assigned

to no zone. The assignment is made individually for each unit.

➋. Standby units

When a sequencing takes place the zone must contain at least one standby unit.

This setting must be made for each unit/IOC by means of the ON/OFF-button on

the InRoom Controller.

➌. Number of defective units (errorunits) (zone parameter)

This entry is optional. If the number, adjusted here, is reached, the emergency

operation will be put into force.

➍. Emergency temperature (zone parameter)

This temperature is the new sepoint when emergency operation is enabled.

Time dependent changeover

The cycletime

➎ determines the lapse of time after which a changeover will peri-

odically take place. This means that the standby status is changed over the units

one by one. With the setting 0 (hrs) no sequencing is made.

Setting the cycletime causes the sequencing start after the sequencing menu has

been left.

To let the standby units (set under item

➋) participate in the sequencing, they have

to be locally switched on by means of the ON/OFF-button on the InRoom Controller.

For this the corresponing unit must be selected in the bus overview window.

Enabling the test sequencing

➏ with the ﬁxed cycletime of 5 minutes helps you to

check the sequencing function.

supply temperature, and supply humidity. The set values can be individually adjusted

for each unit, but they should only vary slightly.

There are two zone speciﬁc functions:

1. Sequencing 2. CW standby management

assigns unit 7 to zone 1

deletes unit 7 from zone 1

puts unit 3 into standby

switches unit 3 on

en- (1) or disables (0) test sequencing

Time dependent change-over

(normal sequencing)

e. g. with 2 standby units:

1. cycle unit 07, 11 standby

cycle unit 08, 14 standby

cycle unit 11, 01 standby

etc.
