Function Guide for the GOLD,
Xzone
1. General
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 venti-
lation 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.
Xzone can be used for all types of GOLD air handling unit
with program version 5.00 or later, and both postheating
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 tem-
perature 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 in section Material
Specification).
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 sys-
tem 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 function requires två IQnomic Plus modules
for wiring temperature sensors as well as an air heater for
postheating and an air cooler. The wiring of temperature
sensors to the IQnomic Plus requires the presence of both
modules in the system even if there is only one air heater
or one air cooler in the zone.
Connect a cable for 0-10 V DC control of valve actua-
tor - heating and cables for control of the pump for the
reheater (if any), supply air temperature and freeze pro-
tection monitor sensors to the IQnomic Plus module
A(function selector switch = A). If an electric air heater
is used, connect the overheating protection alarm signal
cable to the input of the freeze protection monitor sensor.
Connect a cable for 0-10 V DC control of the valve actua-
tor cooling or air cooler for cooling in 1 - 3 steps or cool-
ing pump control and extract air/room air sensors to the
IQnomic Plus module B (function selector switch = B).
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 postheating with freeze protection
monitor is selected for the extra zone, the heat retaining
function operates completely separately. The heat retain-
ing and alarm limit values preset at service level are appli-
cable to both the extra zone and the main zone.
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, cool-
ing will be blocked in both zones.
If intermittent night-time operation is activated, the con-
ditions 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 tem-
perature control settings.
Connect the cable of the air heater for main zone post-
heating 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 air
heater of the extra zone to the screw connection terminals
of the IQnomic Plus module. The heating output cannot
have modular connection and if standard coils for GOLD
with modular connection are used for the extra zone, the
cable will have to be cut.
Important!
The function with output power reduction (for an electric
air heater), activated in the event of low airflows for pro-
tecting the heater elements from overheating, is blocked
when the Xzone is selected. Since the control system
cannot measure the flow in the different zones, the func-
tion is blocked both for the extra zone and the main zone.

6. Performance checks
IQnomic Plus module:
Light-emitting diode L2 lit with a steady glow indicates
that power is being supplied from the GOLD unit’s control
unit.
A flashing light-emitting diode L1 indicates correct com-
munication with the GOLD unit’s control unit.
Temperature sensor:
Current temperatures can be read under INSTALLATION
– READINGS – IQNOMIC PLUS – XZONE HEATING/XZONE
COOLING. 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.
