Function Guide for the GOLD version E/F, Xzone
1. General
2. Material Specification
The Xzone function is designed for controlling one extra
temperature zone via the ventilation system.
Sometimes it is necessary to control a part of the ventilation system with different temperature prerequisites.
This may be due to proximity to the perimeter wall of the
building facing north or south; workshop, office or other
conditions that give rise to different temperature loads in
various parts of a building.
The Xzone function can control one extra temperature
zone, max.
Both re-heating and cooling can be controlled in the extra
zone.
When Xzone is activated, several menus appear in the
hand-held micro terminal under user level for setting and
reading the extra zone parameters.
The type of temperature control for the extra zone must
be selected separately, and can be of another type than
that used in the main zone.
If extract air temperature control is selected, the temperature sensors must be positioned so that they will not
be influenced by the temperature in the other zone. This
means that the internal extract air sensor (inside the air
handling unit) must not be used for control for the main
zone. The room sensor or extra extract air sensor should
be used, (see TBLZ-1-30 or TBLZ-1-24-2 in section Material
Specification).

Supply air temperature sensor, set (TBLZ-1-30), according
to selection above consists of the following:
Duct temperature sensor 32106304
Jack for wall mounting 019611
Extract air temperature sensor, set (TBLZ-1-30), according
to selection above consists of the following:
Duct temperature sensor 32106304
Jack for wall mounting 019611
Room temperature sensor (TBLZ-1-24-2), according to
selection above.
The air heater and air cooler for the main and extra zone
must be sized on the basis of separate computerized
calculations. Always take into account that the duct system where the air heater and air cooler are fitted, does
not have the same dimensions as the connection spigots/
frames of the air handling unit.

3. Operation
The Xzone for heating and Xzone for cooling must each
be activated separately. The type of control signal for the
heating and cooling function respectively must be selected
individually.
Temperature control for the Xzone operates completely
separated from the temperature control of the main zone.
If an air heater for re-heat with frost guard is selected for
the extra zone, the heat retention function will operate
completely separately. The heat retention and alarm limit
values preset at service level are individual for the extra
zone and the main zone.
N.B.!
The function with output power reduction (for an electric
air heater), activated in the event of low airflows in order
to protect the heater elements from overheating, is active
both for the extra zone and the main zone.
In cases where loose IQlogic + modules will be used for
integration into a different existing zone control box, the
Xzone function requires two IQlogic+ modules for connecting supply air and extract air sensors respectively.
The cooling min. flow function applies to the flow from
the air handling unit, not the flow for each zone.
When the total flow reaches below the preset value, cooling will be blocked in both zones.
If intermittent night-time operation is activated, the conditions in the main zone are controlled according to the
settings of the function. When the air handling uit starts
up, the extra zone is controlled according to ordinary temperature control settings.
Connect the cable of the air heater for main zone postheating to the ordinary heating output on the GOLD air
handling unit control unit. Connect the main zone’s cooling control cables to the ordinary cooling outputs on the
GOLD air handling unit control unit. Connect the extra
zone's air heater/air cooler to the TBLZ-3-50 zone control
box.

4. Electrical connections.
See the Installation Instructions for the TBLZ-3-50 zone
control box.
5. To enter settings.
For basic facts on how to use the hand-held terminal, see
the Operation and Maintenance Instructions for the GOLD
air handling unit.
The Xzone function must be manually activated under
Functions/Heat resp. Cool respectively.
1. Activate Xzone under Heat if re-heat is required in the
extra zone. The type of air heater is automatically detected
when the function is connected.

Xzone
2. Set the required values for exercising the pump and
valve (applies to air heaters for water).
3. Activate Xzone under Cool if cooling is required in the
extra zone and select the operating mode. The type of
air cooler for water is automatically detected when the
function is connected. If DX cooling is used, select 1-step,
2-step or 3-step binary operation.
2. Set the required values for exercising the pump and
valve (applies to air coolers for water).
When any of the Xzone heat or Xzone cool functions
is activated, a new image is displayed in the hand-held
terminal: "Temperature regulation Xzone under Functions/
Temperature”.
4. Set the required temperature regulation function for the
extra zone and the required set point.

Temperature sensor:
Current temperatures can be read under TEMPERATURE –
STATUS. If the temperature readings are resonable, wiring
has been carried out correctly.
If the functions are activated but the accessories have not
been connected correctly, an alarm will be initiated. See
the Operation and Maintenance Instructions for the GOLD
unit for a description of each alarm.
