Wiring
• The Zone Manager can be connected to one unit (that is the
first in the network).
• Each unit must be connected one after the other (daisy chain).
• If the Zone Manager is to use its room sensor the controller has to
be located in the same area as the addressed unit(s) number 1.
Power
Note that the Zone Manager requires no batteries and is not
"power stealing". It requires 12 VDC to be connected for proper
operation, which is easily obtained from any of the unit by
means of an auxiliary board.
The Zone Manager will not operate without this connection.

Choosing the installation site
The Zone Manager Location
The Zone Manager can be located anywhere.
However, if the installation requires the systems in the location
in zone 1 to use the Air Sensor on the Zone Manager; then, the
controller should be mounted:
•Approximately 1.5 m from floor.
•In the same area where the units from group are located,
preferably on an inside partitioning wall.
•On a section of wall without pipes or duct work.
If the air sensor on the Zone Manager has been selected, it
should NOT be mounted:
•Close to a window, on an outside wall, or next to a door
leading to the outside.
•Exposed to direct light or heat from a lamp, sun, fireplace, or
other temperature-radiating object which may cause a false
reading.
•Close to or in direct airflow of a heating or cooling supply.
•In areas with poor air circulation, such as behind a door or in
an alcove.
Minimum clearances

GB - 4
ZoneManager
Considerations
• Maximum of 500 m of total network wiring.
• Maximum of 32 units allowed on a system.
• Maximum number of zones 8.
• Only zone 1 can use the room sensor located on the Zone
Manager.
Network wiring must be daisy chained.
CAUTION:
Star configuration can cause improper operation of the
Zone Manager.
Mounting
WARNING:
Before installing the Zone Manager, turn off all power to
the unit that will supply power to the Zone Manager.
Electrical shock can cause personal injury or death.
• Turn OFF all power to unit.
• Open the front door and unscrew the fixing screw placed
near the “FAN” and “LOUVER” keys.
• Open the Zone Manager rear door (mounting base) to expose
mounting holes.
The base can be removed to simplify mounting (snap apart
carefully at hinge to separate mounting base from remainder
of the Zone Manager).
• Route the Zone Manager wires through the large hole in the
mounting base.
Level mounting base against wall (for aesthetic value only the
Zone Manager need not be level for proper operation) and
mark the wall through the 2 mounting holes.
• Drill two 5 mm mounting holes in wall where marked.
• Secure mounting base to wall with 2 screws and anchors
provided, (additional anchoring holes available for more
secure mounting if needed) making sure all wires extend
through hole in mounting base.
• Adjust length and routing of each wire to reach the proper
terminal in the connector block on the mounting base, with 6
mm of extra wire (strip only 6 mm of insulation from each wire
to prevent adjacent wires from shorting together when
connected).
• Match and connect equipment wires to proper terminals in the
connector block (See section "Electrical connections").
Both power and communication wires must be connected
correctly for proper Zone Manager operation.
• Push any excess wire into the wall and against mounting
base.
If the air sensor is being used on the Zone Manager, seal
hole in wall to prevent air leaks.
Leaks can affect sensor operation.
• Snap hinge back together.
• Close the Zone Manager assembly making sure pins on back
of circuit board align with sockets in connector.
• Tighten the fixing screw placed on the unit keyboard.

Unit zone addressing
The units must have their communications address changed to
the zone number in which they will occupy. Figure shows an
example using 9 units and 4 zones. For this example, the
values shown in Table 1 should be used. For this example,
units B, C, E, H, and Iwill occupy Zone 4. Therefore their
communications addresses should be configured to address 4.
The numbering of the zones must begin with Zone 1. Any
further zones must be added in a sequential order.
For example, configuring the zones 1, 2, 3, and 5 will result in
improper operation. (Fault code C4 would be seen).
Configuring the communications address using the
IR remote
The instructions below refer to the unit configuration shown in the
drawing.
•Each unit must have its own address ("UAdr" in the IR remote
control menu) which will be different from the others. The
example shows 9 units, so 9 different addresses will have to
be configured.
•Suppose you want to configure units A and D in room (zone)
1. Keeping the IR remote control OFF, press the keys mode
and louver simultaneously for at least 5 seconds to
access to the 12 configuration menus.
Use "MODE" button to select item "UAdr" and then use and
buttons to select address "1". Now press louver button to
send a message to unit "A". A "beep" confirms the address
reception.
Make sure one same address is not sent to the other units.
•Press button to select address "2" and by means of louver
button send the message to unit "D".
Press mode button again to select item "ZONE". Use
and buttons to select zone "1". Press louver button to
send the message to unit "A" and "D".
Configuration of unit "F" is made as follows:
•If "ZONE" menu is still active, press button to select zone
"2". Press louver button to send the message to unit
"F".
A "beep"
confirms message reception .
If more than 30 seconds have passed from configuration of unit
"D" , the IR remote control exits from the configuration menu
automatically.
If so, go back to the menu as previously described.
•By means of mode button scroll all menus and select
item "UAdr". Use button to select address "3". Press
louver button to send the message to unit "F.
A "beep" confirms message reception .

Test System Installation
To assist with installation wiring and unit zone addressing
issues, an installation test mode exists, that allows the installer
to easily verify that all units, by zone, are communicating
properly with the Zone Manager.
•To enter installation test mode on the Zone Manager, depress
and hold the "LOUVER" button down for 5 seconds. When test
mode is entered, the display will show zone number and
"CONF" in place of the system clock.
•The only buttons that are active at this time are "NEXT ZONE"
and "END PROGRAM".
The Zone Manager will continuously send out messages to the
units in the displayed zone, telling them to flash theirprotect
LED (RED) at a rate of 1 sec on and 1 sec off.
The installer can now visually verify that the units in the zone
are communicating properly with the Zone Manager.
The "NEXT ZONE" button can be depressed to select a new zone
to test. Once the zone is changed, all units in the new zone will
start blinking their protect LEDs, assuming addressing and
wiring is correct. The previous zone will time out and stop
blinking their protect LEDs (RED), after 10 seconds of not
receiving a message from the Zone Manager.
The installer should run this test on all zones in the system, verifying
that every unit is addressed and wired properly. When complete, the
installer can depress the "END PROGRAM" button to disable Installation
Test Mode and have the Zone Manager operate normal again.
Once complete, the installer can be confident that the Zone
Manager will control all of the zones, based upon each zones’o
programming information.

Setback to ON period
If the Zone Manager is currently operating in a Setback period
and the next period is an "ON" period and the setpoint in the
Setback period is the same as the setpoint in the "ON" period,
the unit will ramp the same as going from an "OFF" period to
an "ON" period.

• The Cool setpoint ramps from 30
° C to 27 ° C from 6:30 am
until 8:00 am.
If the Zone Manager is currently operating in a Setback period and
the next period is an "ON" period with a different setpoint, the
following will occur 1.5 hours before the next period is entered.
1.5 hours before the "ON" period starts Smart Start is
activated. The unit will control the room air temperature to the
Setback periods setpoint plus of minus the Auto Mode
Deadband divided by two and ramp towards the "ON" periods
setpoint plus or minus two degrees.
The purpose of Smart Start is so that the room temperature is
at the desired temperature by the time the "ON" period starts.
Smart Start is only valid if the period transition is from " OFF"
to "ON" in "HEAT", "COOL", or "AUTO" modes; or a "Setback" to
"ON" period in "AUTO".
If the Zone Manager has been configured for Smart Start then
the following applies, otherwise period transitions will occur on
time boundaries.
If the Zone Manager is currently operating in an "OFF" period
and the next period is an "ON" period, the following will occur
1.5 hours before the next period is entered.
"OFF" to "ON" period if the operating mode is Heat
If the operating mode is "HEAT", 1.5 hours before the "ON" period
starts, the unit will turn on in Heat mode.
