Introduction
1.1 Notes on these instructions
These instructions contain important information that
should be followed when installing the M-WRG-GW
gateway.
►
Read all the instructions carefully to avoid possible risks and
mistakes.

instructions that were supplied with your unit.
1.2 Description
The M-WRG-GW gateway is used for cloud-based operation of
ventilation units from the M-WRG-II and M-WRG series constructed
from 2020 onwards (excluding bus unit types) via an iOS or Android
app. The gateway forms the interface between the ventilation unit(s)
and the Meltem app. It can be used to control, program and read
the units decentrally, centrally on site or online from anywhere in the
world. It is used to create time programs for different controllers to
suit the unit configuration. The user can also program various unit
functions and sensors. The app is used to create a personal user
account for configuring and managing the gateway. Communication
between the gateway and ventilation units is also established and
controlled via the app. Data protection has top priority; the data is
fully encrypted and can only be released by the user. Up to 20 units
may be logged into a gateway; the number is only limited by the
wireless range.
The following components are needed to control the ventilation units
using the app:
— Ventilation units from the M-WRG-II and M-WRG series
constructed from 2020 onwards (excluding bus unit types)
— Smartphone or tablet, iOS or Android operating system
— Meltem app
— M-WRG-GW gateway with Meltem cable and mains adapter
— Router with Internet access (provided by the customer)
The gateway can also be used in parallel with the M-WRG-FBH
wireless remote control, M-WRG-FT 4-way wireless pushbutton
switch, M-WRG-II FSF wireless humidity sensor and M-WRG-II FSC
wireless CO
