SYSTEM OVERVIEW
SK19-Connect switching contact
Figure 7: SK19-Connect switching contact
The SK19-Connect switching contact (in the following text "switching contact") is a radio interface
and is used to integrate safety devices, e.g. a 4 Pa pressure sensor, into the ventilation system
while simultaneously operating the ventilation system with fireplaces.
WARNING:
For joint operation with fireplaces, safety measures must be taken to prevent a negative pressure
from developing in the building. The responsible chimney sweep and/or building planner decides
which measures need to be carried out.
If this interface is used in conjunction with an external pressure sensor (4 Pa pressure sensor),
the air pressure indoors is continuously monitored. As soon as this exceeds the safety-relevant
limit value, the sensor transmits this to the controller.
The system reacts as follows:
•
The controller switches off all ventilation devices paired with it. The LED on the Easy Connect
e16 controller flashes alternately RED and WHITE.
•
The closing flaps on the Connect inner covers remain open or are opened.
The LED on all Connect inner covers flashes alternately RED and GREEN.
•
The LED on the Sk19-Connect switching contact flashes alternately RED and GREEN.
The function remains active until the air pressure drops below the safety-relevant limit again. Then
all of the ventilation devices connected to the controller switch back to their originally set operating
mode.
If the connection between the switching contact and the controller is interrupted, the system reacts
in the same way as when the safety-relevant limit of the air pressure is exceeded.
