ZONE MASTER with dap4 User’s Guide
1.0 Introduction
The Zone Master offers unit lead/lag, rotation and a teamwork control solution for DataAire units.
The Zone Master consists of one Master Unit and up to fifteen (15) Slave Units. Unit #1 is always
assigned as the Master Unit (U1). Units #2 through #16 are slave units. Zone Master control logic
is configured in the Master unit.
The Zone Master units are connected together in a daisy chain topology using the dap4 pLAN
communication port (see the dap4 Zone Master wiring connections on page 9).
Note: The Zone Master is optional and requires anActivation Code for each unit in the zone.
The Zone Master provides selectable logic choices as listed below:
• Auto Lead/Lag Standby Rotation
• Secondary Operating Schedule for Economical Control
• Activate Standby Unit on Selectable Alarm
• Turn Unit Off Selectable Alarm
• Zone Inhibit Control Preventing Units from Conflicting Operations
• Standby Unit Activation on Temperature Control
1.1 Logic
1.1.1 Auto Lead/Lag Standby Rotation and Temperature Assist Logic – provides a means to au-
tomatically rotate the designation of STANDBY among a group of units that must be ON based on
programmable schedule.
The user may assign a number of units to a zone where a number units must always be ON and
others in STANDBY or OFF. ON units will have a PRIMARY designation on their status page at
the Zone Master’s display screen.
ON units will have a ONbyZM (On by Zone Master) designation at status display.
STANDBY will have a STBbyZM (Standby by Zone Master) designation.
Units that are ONbyZM but do not display the PRIMARY designation, have been brought ON by
the Zone Master because of a temperature requirement or an alarm.
OFF units will have a OFFbyZM (Off by Zone Master) designation.
The OFF mode setting will cause the blower and all cooling, heating, dehumidification and humidi-
fication functions to be held off regardless of the zone’s requirements. The main control display
will display the following message: OFFbyZM
The message will also be displayed in the summary page of the master unit (such as – Status:
OFFbyZM).
5
In the STDBY (standby) mode there are two scenarios:
1. The unit that has been selected to always run (ONbyZM – Primary as shown in the master unit
display) will operate non-stop providing all cooling, heating, dehumidification and humidification
functions required. The blower will run continuously for ventilation and provide airflow across the
sensors for accurate temperature and humidity requirements even if no cooling, heating, dehu-
midification and humidification are required.
2. The standby units that are not required to always run will hold off the blower and all cooling,
heating, dehumidification and humidification functions unless among the units which are ONbyZM
the average return air temperature in the zone is more than the average setpoint plus average
deadband plus 1.5°. If this occurs, one of the STBbyZM will change its status to ONbyZM. The
blower of the standby unit will start and the standby unit will then be allowed to regulate cooling as
if it was in the ON mode. Normal operation messages will be displayed whenever a standby unit
has been reactivated for operation.
If the temperature and humidity condition at the standby unit are satisfied, it will return to inactive
(STBbyZM) when the average zone temperature is maintained below the average setpoint plus
the average deadband for 15 minutes (this is adjustable and has a range from 30 to 999 sec-
onds).
If the temperature or humidity condition at the standby unit isn’t satisfied even though the zone’s
average temperature is maintained below average setpoint plus deadband for 15 minutes (adjust-
able), the unit will continue to run until its temperature and humidity is satisfied. Its status will be
RUNtoSTB (run to standby). Once its own temperature and humidity setpoint is reached, if the
zone average temperature is below setpoint plus deadband, the zone master will turn the unit to
standby and the status will be STBbyZM.
Example - With four units assigned to a Zone, two units must be always ON and one unit always
OFF, the settings are as follows:
Zone Master
Zone ID: 1
Units in Zone: 4
Units Online: 4
Primary Schedule Only
Number of Units On: 2
Zone Master
Note: U1 is the Master
Unit #1: Stdby
Unit #2 Stdby
Unit #3 Stdby
Unit #4 Off
6
Based on the above settings, the zone logic will automatically set unit # 1 and unit # 2 as ONbyZM
(On by Zone Master). Unit # 3 will be STBbyZM (Standby by Zone Master). Unit # 4 will be OFF-
byZM (Off by Zone Master)
Typical Screen (values for reference only):
Units that are set to OFF by the Zone Master do not rotate. Auto rotation start time can be set to
OFF for no rotation or to any hour during the day for rotation. Rotation can be programmed to oc-
cur every 8, 12, 24 hours or day of the week.
Assume 24 hours rotation, on the status page of each unit the following will be displayed:
Unit Number 1 Unit Number 2 Unit Number 3 Unit Number 4
Day 1 ONbyZM ONbyZM STBbyZM Off
Day 2 STBbyZM ONbyZM ONbyZM Off
Day 3 ONbyZM STBbyZM ONbyZM Off
Day 4 ONbyZM ONbyZM STBbyZM Off
Day 5 STBbyZM ONbyZM ONbyZM Off
Day 6 ONbyZM STBbyZM ONbyZM Off
Day 7 ONbyZM ONbyZM STBbyZM Off
Note:
- If communication with the Zone Master is broken, all units will operate independently and
for the first five (5) minutes, the message will displayed at on each unit’s display screen:
“Master (U1) has Gone Offline”
- If communication between a slave unit (for example Unit #3) and the Zone Master is broken,
the Master will exclude Unit Number 3 from its calculation and report on its status loop:
“Unit 3 is Offline”
During this time, Unit Number 3 will operate independently on its own setpoints.
The auto Lead/Lag Standby Rotation Logic is enabled through the Zone Master (see Program-
ming and Selection section).
One unit is designated the Master (U1). Each individual unit may be set to OFF or STDBY (Stand-
by).

1.1.2 Standby Alarm Logic – Within a zone one or more units may be designated as STANDBY
(STDBY) units which are only available when required by an alarm condition. The Zone Master is
designed to detect alarm conditions and to activate standby units as necessary.
Note: Standby unit activation and deactivation are independent of other zones
The user may assign one or more alarms as “Standby Alarms” by selecting Y (yes) in Zone Master
Alarms page (see Zone Master Set-Up). The Zone master temporarily activates standby units to
supplement units that have experienced one or more Standby Alarms per the following rules:
• For each unit in a zone that experiences a Standby Alarm, a standby unit will activated (if
available) in that zone
• Once activated, each activated standby unit remains ON until the Standby Alarm has gone
away and for fifteen minutes (adjustable) thereafter.
1.1.3 OffAlarm Logic – Within each zone one or more units may be designated as Standby
(STDBY) units which are only available when required by an alarm condition. The Zone Master is
designed to detect alarm conditions and to activate standby units as necessary.
Note: - Standby unit activation and deactivation are independent of other zones.
- Off alarm and standby alarm selection can not be duplicated.
The user may assign one or more alarms as “OFF” by selecting Y (yes) in Zone Master Alarms
page (see programming and selections section). The Zone master temporarily activates standby
units to supplement units that have experienced one or more OFF alarms per the following rules:
• Whenever an ON unit is on by the Zone Master (OnbyZM) experiences an OFFAlarm, the
Zone Master immediately reconfigures the unit to OFF (OffbyZM). If there are any standby
units available in the affected zone, the Zone Master reconfigures the standby unit with the
lowest identification (ID) number ON and changes its status to ONbyZM (on by Zone Mas-
ter).
• Any reconfiguration accomplished by the Zone Master in response to Off Alarms continues
until the user manually changes the status setting through the Zone Master’s menus.
• The last ONbyZM unit in the zone will remain on even when an Off Alarm is detected.
1.1.4 Zone Inhibit Control Logic – Logic stops units within the same zone from engaging in coun-
terproductive heating and cooling or humidification and dehumidification at the same time in the
same zone. Reheat is not considered in the Inhibit Logic since it only accompanies dehumidifica-
tion.
The logic in enabled by selecting YES for the Inhibit Control in the Zone Master (see programming
and selections section).
8
The following rules apply:
• Cooling/Heating
o The Inhibit Logic can only be influenced by units that are within 3°F of the average mea-
sured zone temperature. This prevents a unit with mis-calibrated sensor from causing
an inhibit function. Units set to OFF mode are not included in the average.
o If any unit within the zone is currently cooling or starts cooling, then all other units within
the zone are inhibited or prevented from continuing or starting heating.
• Humidification/Dehumidification
o The Inhibit Logic can only be influenced by units that are within 5% of the average mea-
sured zone humidity. This prevents a unit with mis-calibrated sensor from causing inhibit
function. Units set to OFF mode are not included in the average.
o If any unit within the zone is currently dehumidifying or starts dehumidifying, then all
other units within the zone are inhibited or prevented from continuing or starting humidifi-
cation.
NOTE: An “EXCLUDED” message will display on the Zone Master when a unit is excluded from
the zone by temperature or humidity calibration.
1.2 Additional Zone Master Features:
• Sync Slaves TSP (synchronize the units’ temperature setpoint) – With the Zone Master
enabled, under Menu B: Setpoints, users can synchronize the temperature setpoint
and deadband of the Master unit to all its units in the zone by selecting YES at the Sync
Slaves TSP selection. Individual units’ setpoint can be changed at its own controller.
• Sync Slaves Clock (synchronize the slave unit’s clock) – With Zone Master enabled,
under Menu C: Clock/Scheduler, users can synchronize the clock of the Master to all its
units in the zone by selecting YES at the Sync Slaves Clock.
• Primary vs. Secondary Schedule – Users have the option to operate the Zone Master
under a secondary schedule. The user can select the number of units to run in the sec-
ondary schedule and when. The scheduler in the Zone Master will take over the Set-
back Schedule in Clock/Scheduler of Menu C.

2.0 Wiring and Addressing Units within a Zone
2.0.1 Wiring
All communication wire must be at least 22 gauge twisted and shielded pair with a drain line. Up
to 16 units may be connected in any order (daisy chained). Unit addresses must be assigned at
start-up prior to wiring.
Each unit is connected through the unit’s control module pLAN connection (J11 - See dap4 Zone
Master wiring connection drawing for wiring details).
2.0.2 Addressing units within a Zone
10
In pLAN network, both the dap4 controller and the display have separate addresses. “Display Ad-
dress” is he address of the display and I/O Board Address is the address of the dap4 controller.
In a Zone Master network where all units are connected via pLAN, each unit and its display must
have different addresses. Below is the recommendation addresses combination:
Table 1: Recommended Addresses in Zone Master control
Unit 1 Unit 2 Unit 3 Unit 4 Unit 5 Unit 6 Unit 7 Unit 8
dap4 pLAN address 12345678
Display Address 32 31 30 29 28 27 26 25
Unit 9 Unit 10 Unit 11 Unit 12 Unit 13 Unit 14 Unit 15 Unit 16
dap4 pLAN address 9 10 11 12 13 14 15 16
Display Address 24 23 22 21 20 19 18 17
2.0.3 Changing the address of the dap4 controller:
Since all units will be shipped as Unit #1, a change of Controller Addresses needs to be done in
order to establish a Zone Master communication.
Follow this procedure to set pLAN address to each dap4 controller in the zone:
• Press buttonA for 5 seconds by using a small screw driver or a small pin. The pLAN ad-
dress will start flashing.
• Press repeatedly or hold the button until reaching the required address (2, 3, 4…16).
Note: You can set up dap4 address from 1 - 16. Address 17 to 32 are reserved for display mod-
ules. Follow the table on previous page to set the display module address.
• Wait until the address starts flashing rapidly. In this stage the address has been saved but it
not yet active for the application program. Power down the controller.
• Power up the controller again. The address is now set to the dap4
Figure 1: Address pin on dap4 controller
2.0.3.1 Changing the Address of the Mini dap4
Change the display module address to 00 by holding three buttons (UP+ENTER+DOWN) at the
same time. A screen will appear showing addresses of the display terminal and I/O board. Use
