Installation, connection and control of accessories
Peripheral Control Capability (EXT-CTRL)
The Airobot can be used to control the heating and cooling circulating pump via the EXT 1
output. The heater is connected to the circuit in the presence of geothermal heating and the Airobot
switches on a separate circulation pump. In winter it is possible to preheat the outside air and in
summer to cool the supply air. The output operates on the normally opened (NO) principle and the
cable of the circulation pump L must be connected to socket C in the electrical panel EXT1 and
continued to the pump via the NO terminal. The pump is powered externally. Driving capability is not
standard and is available as an option.
Connection to an automatic fire alarm system (ATS)
The device can be connected to the ATS system in the house, which automatically shuts off when it
receives a signal in the event of a fire (NO - normally opened contact). The ATS is connected to the
FIRE output under the GND and STOP contacts. ATS system capabilities are standard with each
device.
The connection of outdoor units, building automation and other similar systems to the ventilation unit
must be carried out by a qualified specialist!
Connecting the pressure switch
Kitchen air purifiers create a temporary negative pressure in the premises, which is not beneficial for
building structures. A pressure switch is available as an option, which is installed next to the kitchen
hood piping so that the ventilation unit automatically switches to overpressure mode when the hood is
started. It is also possible to connect another contact that signals the start of the hood - the contact
must be normally opened.
