Installation Instructions for the
TBIQ-2-1-aa IQnomic Plus Module
GOLD/COMPACT
1. General
The IQnomic Plus is used for extra functions for which
inputs and outputs are not included as standard in the
control unit of the air handling unit.
2. Installation
Mount the IQnomic Plus at a suitable location. One helpful
hint is to mount the module at an unoccupied spot on the
rail inside the control cubicle of the air handling unit.
Wire the IQnomic to the control unit inside the electrical
equipment cubicle of the air handling unit.
Connect the communication cable, supplied with the unit,
to one of the connections on the module. It is not im-
portant which connection is used. The reason why there
are two connections is to make it possible to connect seve-
ral IQnomic in series.
Connect the other end of the communication cable to one
of the connections of the control unit, marked Internal
EIA-485.

The IQnomic Plus module is used for the ReCO2 function
(function selector switch set to position 0, see Figure 1).
The function is activated in the GOLD unit’s hand terminal
or via the communication interface.
The module controls mixture and outdoor air dampers.
Connect signal response from the mixture damper’s actua-
tor to terminal 18 (+) on the module. Do not connect
outdoor air damper’s signal response, monitoring is carried
out by the unit’s flow alarm.
Connect the control signal for the mixture damper’s actua-
tor to terminal 14 (+) on the module. Connect the control
signal for the outdoor air damper’s actuator to terminal 6
(+).
If the function is to be controlled from an external CO2
sensor, or similar with signal 0- 0 VDC, connect it to termi-
nal 9 (-) and 20 (+).
Intermittent night-time heating + extra control se-
quence
The module can also be used for a combination of the in-
termittent night-time heating and extra control sequence
functions (function selector switch in position 0, see Fig.
1).
Connect the air recirculation damper just like you would
for the ReCO2, see Fig. 2.

4.3 Coil heat exchanger
The IQnomic Plus module is used for the coil heat exchan-
ger function.
An IQnomic Plus module is installed, as standard, in all
GOLD CX air handling units. The IQnomic Plus module’s
function selector switch is set to Position 1.
The module controls the circulation pump of the pipework
package and the valve actuator on the coil heat exchan-
ger.
A limiting sensor is connected to the module. Readings
from the temperature sensor (strap-on type) prevent the
water circulating through the extract air coil from reaching
such low temperatures that freezing is likely.
The GOLD CX unit requires communication with an IQno-
mic Plus module (1) so that no alarm will trip.
The contactor for controlling the circulation pump is con-
nected to terminals 1 and 2 on the module.
Signal response from the contactor is connected to termi-
nals 7 and 8 on the module.
The control signal (Y) for the valve actuator is connected
to terminal 6 (+) on the module.
The valve position signal (U) is connected to terminal 20
(+) on the module.
The conductors for supplying 24 V AC power to the valve
actuator must be connected to Terminals 203 (G0) and
204(G). A jumper must be fitted between Terminal 12 on
the module and Terminal 203 (GO) to give reference to
control signals.
Connect the temperature sensor conductors to Terminals
24 (white wire) and 23 (brown wire).

4.4 Plate heat exchanger
The IQnomic Plus module is used for the plate heat
exchanger function.
An IQnomic Plus module is installed, as standard, in all
GOLD PX air handling units. The IQnomic Plus module’s
function selector switch is set to Position 2.
The module controls the by-pass and shut-off damper
actuators on the plate heat exchanger.
Two limiting sensors are connected to the module.
Readings from the temperature sensor (strap-on type)
prevent the temperature in the foil, in the extract air pas-
sages of the heat exchanger cube, from reaching such low
temperatures that freezing is likely.
The GOLD PX unit requires communication with an IQno-
mic Plus module (2) so that no alarm will trip.
The control signal (Y) for the damper actuator is connec-
ted to terminal 6 (+) on the module.
The damper actuator signal response (U) is connected to
terminal 20 (+) on the module.
The conductors for supplying 24 VAC power to the valve
actuator must be connected to Terminals 201 (G0) and
202(G). A jumper must be fitted between Terminal 12 on
the module and Terminal 201 (GO) to provide reference to
the control signals.
Connect the conductors of the one temperature sensor
to Terminals 24 (white wire) and 23 (brown wire); those
of the other sensor to Terminals 22 (white wire) and 21
(brown wire) with the other.

PACT and GOLD
Select external cooling control in the hand-held micro
terminal of the air handling unit (function selector switch
set to position 6, see Figure 1).
When the IQnomic Plus module is used for control-
ling other types of cooling circuit valves or cooling units
(external cooling control), the inputs must be fitted with a
jumper (if they are not used for external alarms). Jumpers
must also be fitted from terminal block 14 to terminal
block 20 and terminal block 18 (if they are not used for
external in-service pressure switches).
IQnomic Plus Module Number 6 must be manually activa-
ted in the hand-held micro terminal.
Relay outputs, DO 1 (terminal block 1-2) and DO2 (ter-
minal block 4-5) are used for on/off controlling of the
cooling units or the circulation pump in the cooling water
circuit.
The digital inputs, DI 1 (terminals 7-8) and DI 2 (terminals
9-10), can be used for external alarms with normally-
closed function (alarms 85 – 86).
The AO 1 analogue output (terminal block 15 (+)) is used
for modulating 0-10 V to the actuator for the cooling
circuit valve or the cooling unit with capacity regulation.
The AO 2 analogue output (terminal block 14 (+)) is used
for modulating 5 V as a reference for supervising the in-
service pressure switches, for instance, via analogue inputs
AI 1 and AI 2. 0V in on input AI 1 stops output DO 1 and
0 V in on input AI 2 stops output DO 2. Each relay is ener-
gised when the input has 5 V in again and the restarting
time has expired.
