Function
- The MAX! Radiator Thermostat basic is responsible for regulating the radiators within the MAX! system. During ventilation, the MAX! Radiator Thermostat automatically reduces the temperature in a room in order to save on energy costs.
- Communication between the MAX! components is bidirectional.
- This ensures that the information sent reaches the recipient.
- The configuration of the MAX! Radiator Thermostat depends on the system variant used. You have the possibility to choose between the following two variants:
MAX! House solution
This is the solution for the entire house. With a MAX! Cube, all settings of connected devices in your house can comfortably be made via the MAX! software
By using the MAX! Cube, several MAX! Radiator solutions and MAX! Room solutions can be connected to a new MAX! House solution in a new installation. In this installation, the MAX! Eco Switch can optionally be integrated.
MAX! Room solution
- In the room solution, the settings of all connected devices in your room can comfortably be made via the MAX! Wall Thermostat+. Up to 8 MAX! Radiator
- Thermostats and 8 MAX! Window Sensors can be connected and controlled via the MAX! Wall Thermostat+.
- The MAX! Wall Thermostat+ has an internal sensor that measures the temperature in the room and cyclically transmits it to the radiator thermostats.
- With a MAX! Cube, the solution can be extended to a House solution.
Device overview
Display content in normal mode
The setpoint temperature is displayed during normal operation, along with the mode. In the example, the MAX! Radiator Thermostat is in automatic mode (Auto) and the comfort temperature ( 
) of 21.0°C is set. The antenna symbol ( 
) indicates that the connection to the taught-in component has been established
Start-up
Inserting (replacing) batteries
In the initial state, the batteries are already inserted. Simply remove the insulation strip.
To replace the batteries, please proceed as follows:
- Press the battery compartment cover on both sides with your fingers and remove the cover by pushing it downwards.
- Insert 2 new LR6/mignon/AA (1.5 V) batteries in the battery compartment, making sure they are the right way round.
- Reattach the battery compartment cover and latch it into place.
After inserting batteries, the radiator thermostat has to be mounted on the radiator (see sec. “6.2 Installation on the radiator” on page 11). The radiator thermostat starts an adapting run afterwards (see sec. “6.3 Adaption run” on page 15).
Information
- A battery symbol (
) on the display indicates that the batteries need to be replaced. After removing the empty batteries, wait approx. 1 minute before inserting the new ones. - The service life of new alkaline batteries is approximately two years.
- Operation with rechargeable batteries is not possible.
- Never recharge standard batteries. Doing so will present a risk of explosion. Do not throw the batteries into a fire! Do not short-circuit batteries.
- Never recharge standard batteries. Do not throw the batteries into a fire. Do not expose batteries to excessive heat. Do not short-circuit batteries.
- Doing so will present a risk of explosion
Installation on the radiator
The MAX! Radiator Thermostat is easy to install and can be done without draining heating water or intervening in the heating system. No special tools are required, nor does the heating have to be switched off. The union nut attached to the radiator thermostat can be used universally and without accessories for all valves with a thread size of M30 x 1.5 from the most popular manufacturers such as
- Heimeier
- MNG
- Junkers
- Landis+Gyr (Duodyr)
- Honeywell-Braukmann
- Oventrop
- Schlösser
- Comap
- Valf Sanayii
- Mertik Maxitrol
- Watts
- Wingenroth (Wiroflex)
- R.B.M
- Tiemme
- Jaga
- Siemens
- Idmar
By means of the adapter in the delivery, the device can also be installed on radiator valves of type Danfoss RA.
Removing the old dial
Rotate the thermostat dial to the maximum value (1) (anti- clockwise). The thermostat dial then no longer presses against the valve spindle, making it easier to remove. There are different ways of fixing the position of the thermostat dial:
- Union nut: Unscrew the union nut in an anticlockwise direction
- The thermostat head can then be removed (3).
- Snap-on fastenings: Thermostat dials that have been attached using this method can be easily released by giving the lock/union nut a slight turn in the anticlockwise direction
- The thermostat head can then be removed (3).
- Compression fitting: The thermostat dial is held in place by a mounting ring which is held together with a screw.
- Loosen this screw and remove the thermostat head from the valve (3).
- Threaded connection with set screw: Loosen the set screw and remove the thermostat head (3).
- In case of visible damage of the existing radiator, valve or heating pipes, please consult a specialist.
Danfoss RA adapter
The provided adapter is required for installation on Danfoss RA valves. The Danfoss valve bodies have elongated notches (G) around their circumference (see arrow), which also ensure that the adaptor is properly seated when it snaps on. Please ensure that you do not trap your fingers between the two halves of the adapter! During installation, please ensure that the pins inside the adapter (H) are lined up with the notches (G) on the valve. The RA adapter has been manufactured with pre-tension in order to provide a better seat. Use a screwdriver during installation if necessary, and bend it open slightly in the vicinity of the screw. Ensure that the adapter is properly clipped on. After clipping onto the valve body, please attach the adapter using the provided screw and nut.
Support ring
The valves from different manufacturers may have tolerance fluctuations that make the radiator thermostat more loosely seated on the valve. In this case, the provided support ring (I) should be placed into the flange before mounting the radiator thermostat.
Adaption run
Once the batteries have been inserted, the motor reverses; meanwhile, “InS” and the activity symbol ( 
) are displayed. As soon as “InS” is displayed without the activity symbol ( ), the radiator thermostat can be mounted. This is followed by an adapting run (“AdA”) to adapt the thermostat to the valve.
- Attach the radiator thermostat to the valve (see sec. “6.2 Installation on the radiator” on page 11).
- Tighten the union nut.
- Press the control wheel shortly when “InS” is displayed.
- Now the radiator thermostat performs an adapting run. “AdA” and the activity symbol ( ) are displayed; during this time, operation is not possible.
- If the adapter run has been initiated prior to mounting or if an error message (F1, F2, F3) is displayed, press the control wheel; the motor reverses to the “InS” position.
- Teach-in mode can be activated even whilst “InS” is still displayed.
- If the MAX! Radiator Thermostat has not been taughtin to a MAX! Cube or Wall Thermostat+, the device automatically switches to manual operation (Manu).
Teaching-in
In order to be able to use the MAX! Radiator Thermostat in your installation, you must teach it in first. The teach-in procedure depends on the system variant used. Choose your system variant (House or Room solution) and follow the instructions below.

- In the MAX! Room solution you can individually configure your week programs via the MAX! Wall Thermostat.
- Manu: Manual operation – the temperature set manually using the control wheelheel is maintained permanently.
- If the operating mode is changed on one device in a room, this change is applied on all MAX! Radiator
- Thermostats assigned to that room.
Boost
If, for example, you arrive home earlier than usual, the boost function will help you to heat the room up quickly. When activating the boost function, the heating valve is immediately opened to 80 % for 5 minutes (factory setting). The heating of a room takes longer than 5 minutes, but the heat given off by the radiator can be felt immediately.
- Press the control wheel shortly to activate the function.
- The remaining time for the function will be counted down in seconds (“b300” to “b000”). Whilst the function is active, is displayed.
- The activity symbol ( ) is displayed as long as the adjusting pin opens/closes the valve.
- Once the boost time has elapsed, the radiator thermostat switches back to the mode that was active previously (Auto/Manu), with the temperature that was set previously.
- The function can be deactivated prematurely at any time by pressing the control wheel again.
- The radiant heat will not have an immediate effect if the radiator is covered or concealed (e.g. by a sofa).
- In the MAX! House solution you can individually configure the duration of the boost function via the MAX! software.
- In the MAX! Room solution you can individually configure the duration of the boost function via the MAX! Wall Thermostat.
- If the duration of the boost function is set (via the MAX! Cube or the MAX! Wall Thermostat+) so that the display exceeds 999 seconds, the display value switches from seconds to minutes.
- If a long boost duration and a large valve opening have been set the radiator can get very hot. After changing the factory setting check that the radiator is not heated excessively.
Comfort and reduction temperature

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. 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.
