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
Zone Manager
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 I will 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

T est 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.
EXAMPLE OF SMART START FOR AUTO MODE: Auto Mode Deadband = 10
TIME SETPOINT TYPE OF PERIOD 12:00 am 25° C SETBACK 8:00 am 25° CON

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. The unit will control the room air temperature to the "ON" periods set point minus 5 degrees. The controlling set point will then ramp to the "ON" periods set point.
