Safety instructions
The installation notes in the section “Installation” must
be observed! Ignoring installation instructions can cause
fires or other hazards.
Make sure that the specified wiring and wire cross-sections are used when connecting to device terminals.
Do not use the device if there are signs of damage to the
housing or connecting sockets, for example, or if it
demonstrates a malfunction. If you have any doubts,
please have the device checked by an expert.
In order for the device to be connected to the supply
voltage and the consumer load work needs to be carried
out on live voltage-carrying parts. Before connecting the
device, remove the fuse from the fuse box.
Using the device for any purpose other than that
described in this user manual does not fall within the
scope of intended use and shall invalidate any warranty
or liability. This also applies to any conversion or
modification work. The device is intended for private use
only.
The circuit to the which the device and the load will be
connected has to be secured by a cable protection switch
in accordance with EN60898-1 (tripping characteristic B
or C, max. 16A rated current, min. 6kA interrupting
rating, energy limiting class 3).

With the MAX! Boiler Controller you can control your central
heating and hot water tank according to your personal needs.
You can easily adjust the times and temperature for your heating and hot water via PC from home or via smartphone app,
no matter where you are.
The device has two channels:
• MAX! Central heating for controlling your heating and
• MAX! Hot water for controlling your warm water tank.
Each channel can be controlled independently.
The configuration of the device is done via the MAX! software.
Therefore, simply connect the MAX! Boiler Controller to the
MAX! Cube. Then set up your individual week programs with
temperatures and times according to your personal needs.
With the smartphone app, you can control your system even
while being away from home.
You can control the channel “Central heating” also via
the MAX! Wall Thermostat+ and the Boiler Controller,
without the need of a MAX! Cube or Internet connection.
In this case, the configuration of your heating is done
directly on the MAX! Wall Thermostat+. Simply install the
MAX! Wall Thermostat+ in a room of your house or flat
that is frequently heated and connect the MAX! Boiler
Controller with the device. For further information,
please refer to the user manual of the MAX! Wall
Thermostat+.

Note. Only to be installed by persons with the relevant
electro-technical knowledge and experience!
Incorrect installation can put
• your own life at risk;
• and the lives of other users of the electrical system.
Incorrect installation also means that you are running the risk
of serious damage to property, e.g. because of a fire. You may be
personally liable in the event of injuries or damage to property.
Contact an electrical installer!
Specialist knowledge is required for installation!
The MAX! Boiler Controller can be easily mounted to pattress
boxes or simply on the wall.

• Turn the screws into the plugs so that they protrude from
the wall by approx. 1.5 mm.
• Mount the device on the wall. Hang it using the brackets
on the back behind the screw heads.
• Pass the cables through the strain relief clamps.
• Connect the cables of the central heating and hot water
tank to the terminals as described in the wiring diagram

In order to integrate the MAX! Boiler Controller into a MAX!
system it has to be connected to the MAX! Cube via the MAX!
software first. All settings and programming (e.g. week programs) can be done via the MAX! software afterwards.
You have to teach-in the two channels (MAX! Central heating
and MAX! Hot water) separately.
• Start the local MAX! software and click on “New device”.
• Press and hold down the first channel button (B) of the
MAX! Boiler Controller for at least 3 seconds to activate
teach-in mode. The channel LED will start flashing green.
• The first channel will appear in the software.
• Press and hold down the second channel button (D) of the
MAX! Boiler Controller to activate teach-in mode of the
second channel.
• The second channel will appear in the software as well.
• Click on “Next” in the software to give the device a name
and assign it to a room.
• The MAX! Boiler Controller is now integrated into the
system and can be configured for each room via the MAX!
software or the smartphone app.

15
Manual operation
In the MAX! software, you need to create one separate
room for the channel “Central heating” and one for the
channel “Hot water”. The channel “Central heating” can
also be used in rooms that include a MAX! Wall Thermostat+ already.
If you want to use your system without a MAX! Cube, you
can also directly teach-in the channel “Central heating”
to the MAX! Wall Thermostat+.
7
With the channel buttons B or D, the single channels can be
switched on and off directly on the device. If the device is operated in connection with a MAX! Cube or MAX! Wall Thermostat, the set comfort or eco temperature will be applied.
Manual operation of “Central heating” channel:
• Press the channel button B shortly.
The central heating is switched on until the next time the current week program changes.
Manual operation of “Hot water” channel:
• Press the corresponding channel button D shortly.
This activates the Boost function: the hot water tank will be
switched on for 60 minutes.
By the end of the Boost phase, the channels automatically
change back to the prior operating mode.

16
Response to power recovery
You can also activate the Boost function via the MAX!
Wall Thermostat+. Simply press the Boost button to
activate the function.
8
resPonse to Power recovery
After power recovery, the device starts with both channels in
MANU Off mode (regardless of the previously set mode).
As soon as the MAX! Boiler Controller receives time information from the MAX! Cube or Wall Thermostat, the channels
switch into AUTO mode (only if a Cube or Wall Thermostat has
been taught-in to the corresponding channel).
If any action is carried out by the user, e.g. operation/configuration of mode, setpoint temperature, week program, profile
settings etc., the channel switches into AUTO mode as well.
9
The factory settings of the MAX! Boiler Controller can be restored manually. Restoring the factory settings deletes all
settings and information about taught-in devices.
First delete the device from the MAX! software.
• Press and hold down both channel buttons (B and D) si-
multaneously for at least 10 seconds.
• Release the buttons. The channel LEDs first go off and
then start flashing 4 times shortly.
• The factory settings will be restored.

The product does not require any maintenance. Enlist the help
of an expert to carry out any repairs. Clean the product using
a soft, lint-free cloth that is clean and dry. You may dampen the cloth a little with lukewarm water in order to remove
more stubborn marks. Do not use any detergents containing
solvents, as they could corrode the plastic housing and label.

InformatIon about raDIo oPeratIon
Radio transmission is performed on a non-exclusive transmission path, which means that there is a possibility of interference occurring. Interference can also be caused by
switching operations, electrical motors or defective electrical
devices.

18
Technical specifications
The range of transmission within buildings can differ
greatly from that available in the open air. Besides the
transmitting power and the reception characteristics of
the receiver, environmental factors such as humidity in
the vicinity have an important role to play, as do on-site
structural/screening conditions.
eQ-3 AG hereby declares that this device complies with the
essential requirements and other relevant regulations of Directive 1999/5/EC. You can find the full declaration of conformity at www.eQ-3.de.
