9 Special functions
Shutter function: The switching contact closes
as soon as the fans switch on. If there is no
speed, the contact opens. This also happens dur-
ing pauses when operating with humidity protec-
tion.
Cooling function: The switching contact closes
as soon as the max. room temperature has been
exceeded.

9.5 Contact for external safety device

An external safety device (differential pressure
controller, smoke detector, fire alarm control
panel) can be connected to terminal X2 (12 V).
Air-ventilated fireplaces
If the ventilation unit is being operated at the
same time as an air-ventilated fireplace, a differ-
ential pressure controller is needed as the safety
device. The differential pressure controller pre-
vents the ventilation system from being operated
if the air pressure in the fireplace's installation
area falls by the permitted pressure in relation to
the flue draught. If this happens, the ventilation
unit switches off. The differential pressure control-
ler is connected as a normally closed contact.
When the impermissible partial vacuum is
reached, the differential pressure controller opens
and thereby directly interrupts the current supply
to the fans. An electric heat register, if present,
shuts off too. Info: The note "External safety shut-
down triggered" appears on the control unit. If the
differential pressure controller is closed, the vent-
ilation unit starts up again.
External safety device
If the safety device connected to terminal X2 (12
V) is triggered (pressure error, smoke etc.), the
ventilation unit shuts down automatically.

9.6 Switching test

A switching test can be used to check the follow-
ing unit or accessory components.
• Supply air / outside air fan
• Exhaust air / outgoing air fan
• Bypass shutter
• Heat register (on main board)
• Switching contact Basic circuit board (main
board)
• Brine circulation pump (with ZP 1)
• Zone shutter, zone 1 and 2 (with ZP 1)
• 3-way air shutter (with ZP 1)
• Supplementary heating relay (with ZP 1)

You receive information as to whether the
components are currently switched on or off
and/or are open or closed.
9.7 Connection via network/web
server
WARNING! Danger of electric shock. Before
removing the service cover, disconnect the
ventilation unit at all poles from the power
supply, secure against being accidentally
switched back on and position a visible warn-
ing sign.
1. Connect ventilation unit and PC* with the
router/network using a patch cable.
* System requirements: PC with Internet ac-
cess and Internet Explorer of at least version
11.
2. On the PC/notebook, set the IP address to
automatic (DHCP) and save the setting.
3. Enter http://maicokwl in the Internet browser's
address line. An input window appears.
4. As a user: Enter user name `admin´. There is
no need to enter a password. The web server
opens.
As an installer: Enter user name `service´ and
password 6940. The web server opens. Info:
You can now access your ventilation unit from
any PC in your network via http://maicokwl.
5. Undertake commissioning.
6. Remove connection cable. Fit service cover
and front plate.

9.8 Operation via app / web tool

1. Make connection. In step 2, under Settings/In-
ternet in the web server also set air@home
parameter to yes.
2. Call up AIR@home web tool (www.air-
home.de) or AIR@home APP.
3. Log in with the access details e-mailed to you
during registration.

9.9 Factory settings

Unit settings are permanently lost with the
factory settings. Back up the data with the
commissioning software before resetting. The
unit settings can be reset with the two factory
settings functions.
Resetting customer & installer level
Complete factory setting, all unit parameters are
reset to the factory settings.
