1.4. External elements connection
Depending on the model of a Domekt air handling unit and component parts, several additional cables can be led
outside the unit for connecting external elements of the automatics:
•
External control contacts.
They are designed in all Domekt units. Outside the unit, a cable is led (see Picture
1.4 a), to which an external control device (switch, sensor, timer, button, etc.) can be connected, i.e. interconnection
of normally open contacts (short circuit) will activate the OVR function. A more detailed description of connection
possibilities is presented in Chapters 2.6 and 3.6.
•
External control box.
If a water heater or a cooler is designed in the Domekt unit, then the unit is fitted with an
external control box (see Picture 1.4 b), which is connected to the unit with a JW1 cable. Some elements specified
below are connected to the contacts of the box.
The connection diagram of the external elements is presented on the internal
side of the doors of the control box.
•
Air damper actuator.
Domekt air handling units can be ordered with the prepared connection for air damper
actuators. In this case, an additional cable is led outside the unit. 230V AC supply and control voltage is provided
for the connection of the actuator.
Note:
For units with water heater the connection of air damper actuators is designed from the external control box;
therefore, connection should not be ordered additionally.
For all units with a water heater, it is recommended to connect an actuator
with a spring-return mechanism, i.e. in the case of loss of voltage, the actuator
should close the air damper.
