• Inputs (5–10)
– to switch between the “Kitchen”, “Fireplace”, “Override” ventilation modes (see “Domekt User Guide”),
connect the respective terminals together with the common terminal 5 (ventilation modes will operate until the termi-
nals are connected). To activate these modes, a switch, a motion detector or kitchen hood with normally open contacts
(NO) can be connected to the terminals. Each function may have a separate switch.

Example of “Override” ventilation mode activation when using additional air extraction
with a motorised damper (see Fig. 9).
Fire alarm requires a normally closed contact (NC), therefore, a jumper is connected between terminals 5 and 7, instead
of which, building fire system can be connected. When the contact is disconnected, the unit is stopped and a fire alarm
message is displayed. The control terminal 6 is required for switching between heating and cooling functions when the
duct is equipped mounted water heater is used for both heating and cooling. When in the settings “External coil” type
is selected as “Auto” (see “Domekt User Guide”), the water mixing valve and the water pump will be controlled by the
heating signal if terminals 5/6 are open, and by cooling signal if the terminals are closed. For example, a thermostat can
be connected here to close the terminals when cold water circulates in the system.
• AUX (11–14)
– can be used for connection of additional elements that require a 24 V power supply and when there are no
dedicated terminals (for example, to connect a second control panel). 0...10 V signal is used to control an external heater
installed in the duct upstream the unit when “External coil” is selected in the “Frost protection” settings (see “Domekt
User Guide”) and electrical pre-heater installed in the unit is not used.
• DX (15–16)
– control signal for external direct expansion (DX) cooler/heater.
• TG1 (17–19)
– power and control signal for the mixing valve actuator of the external heat exchanger for mixing. Depend-
ing on the “External coil” type selected in the settings (see “Domekt User Guide”), the valve actuator will be controlled
by a heating or cooling signal.
• RS485 (20–21)
– data cable connection, to control the unit from a building management program via Modbus RTU pro-
tocol.
• B6/B7 (22–27)
– if VAV airflow control method is used (see “Domekt User Guide”), it requires the installation and con-
nection of optional pressure sensors in the ducts. Follow the manufacturer’s instructions when installing VAV pressure
sensors. Also, these terminals are used for DCV airflow control when a separate 0...10 V signal can be used to adjust the
ventilation intensity (see “Domekt User Guide”).
• B8/B9 (28–33)
– for connection of air quality or humidity sensors for “Air quality” function. When the sensors are con-
nected, its type and connection point must be specified in the settings (see “Domekt User Guide”).
• Outputs (34–37)
– the terminals are used when external heating/cooling units require an additional closed/open con-
tact (i.e. to start the DX unit). The corresponding contacts are closed depending on whether the air handling unit heats or
cools. The alarm signal contact is closed if the air handling unit has critical messages and its operation is stopped.
• FG1 (38–40)
– terminals used to connect air damper actuators. 230 V power supply actuators with or without a spring
return can be connected to them.
• S1 (41–42)
– a water circulation pump used in conjunction with external water coils and is activated when required for
heating/cooling.
