Inserting (replacing) batteries

Pull off the battery compartment cover.
Insert 2 LR6 (mignon/AA) batteries in the battery compartment, making sure they are the right way around.
Replace the battery compartment cover and latch it into position.

The service life of new alkaline batteries is approximately two years. A battery symbol () indicates that the batteries need to be replaced. After removing the batteries, wait approx. 1 minute before inserting the new ones. This device does not support battery operation. T A 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. Once the batteries have been inserted, the radiator thermostat starts an adapter run. You can confirm this with the Boost button. For more details, see the next section, “Mounting on a radiator”.

Mounting on a radiator

The radiator thermostat can be mounted on all standard heating valves. There is no need to drain away water or to fiddle around with the heating system. Start by removing the old thermostat dial.

Turn the thermostat dial anticlockwise as far as it will go (A).
Unfasten the thermostat dial (B).
Pull the thermostat dial off the valve (C).

Some valves require the use of an adapter. Adapters for Danfoss valves (RA, RAV, RAVL) are supplied with the product. For more details, please see the list of adapters on page 16.

Attach the valve adapter to the valve and turn to secure.
If you are using a RAV adapter, also attach the extension supplied to the valve tappet.
Use the screw and nut supplied for additional fastening of RA and RAV adapters.

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 electronic radiator thermostat can be mounted. This is followed by an adapter run (“AdA) to adapt the thermostat to the valve.

Attach the radiator thermostat to the valve.
Tighten the union nut.
Press the boost button when “InS” is displayed.

The actuator performs an adapter run. “AdA” and the activity symbol () are displayed; during this time, the 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 Boost button; the motor reverses to the “InS” position. If the MAX! The radiator Thermostat has not been taught in on the MAX! Cube, the device automatically switches to manual operation (Manu). Teach-in mode can be activated even whilst “InS” is still displayed.

Teaching-in on MAX Components

In order to enable communication between MAXI Components. the devices have to be taught-in to one another.

Start by switching the teach-in partner (e.g. the MAXI Cube) to teach-in mode.
To activate teach-in mode on the radiator thermostat Press and hold down the Boost button for at least 3 seconds. The antenna symbol ( ) is displayed, along with the teach-in time remaining in seconds. The teach-in time is 30 seconds.

IMPORTANCE

As soon as the MAX! Radiator Thermostat has been taught in on a gateway like the MAX! Cube, all data such as date, time, or weekly program are transmitted to it via the radio connection.
Without a gateway, the MAX! Radiator Thermostat can only be used in manual mode; it cannot be switched to automatic operation.
The MAXI Radiator Thermostat can only be taught-in in one gateway (e.g. the MAX! Cube).

Teach-out/Reset

The MAX! Radiator Thermostat can be reset to the initial state manually. Restoring the initial state deletes all settings and information about taught-in devices.

First,1 0. Information displayed during normal operation
The current temperature is displayed during normal operation, along with the mode. In the example on the right, the MAX! The radiator Thermostat is in automatic mode (Auto) and the comfort temperature { 􀀁f􀀂 ) of 21.0°c is set. The antenna symbol { (fl ) indicates that the connection to the taught-in component has been established.
11 . Child-proof lock/Operating block
Operation can be blocked on the device. remove the batteries from the actuator.
Wait 60 seconds.
Press and hold down the three buttons (Auto/Manu, Boost, ).
Re-insert the batteries.
Once the factory settings have been restored successfully, “rES” is displayed.

Operating modes (Auto/Manu/ )

To switch between operating modes, press and immediately release the Auto/Manu button (the operating modes only become available for selection once the installation is complete).

Manu: Manual operation – the temperature set manually using the handwheel is maintained permanently.
Auto: Weekly program – automatic temperature regulation in accordance with the time profile saved (heaVreduce).
Holiday (): In holiday mode, the set temperature is maintained up to an end time, at which point the device switches to automatic mode. Can only be deactivated on the radiator thermostat; activation is via a gateway (e.g. MAX! Cube).

If the operating mode is changed on one device in a room, this change is applied on all radiator thermostats assigned to that room.

Boost function

The boost function makes use of human sensations of heat. When the function is activated, the heating valve opens immediately for 5 minutes at 80% (factory setting). You can feel the heat from the radiator immediately and at the end of the 5 minutes, the room continues to heat up. If you arrive home earlier than usual and want to heat the room up quickly, or you need some extra heat in the morning after a shower, then the boost function will help you with this.

Press the Boost button to activate the boost function.
The remaining time for the function is counted down in seconds (“300” to “000′). Whilst the function is active, is displayed.
The activity symbol () is displayed as long as the adjusting pin opens/closes the valve. Once the set time has elapsed, the radiator thermostat switches back to the mode that was active previously (automatic/manual), with the temperature that was set previously.
The function can be deactivated prematurely at any time by pressing the Boost button again.

The radiant heat will not have an immediate effect if the radiator is covered or concealed (e.g. by a sofa).
If the duration of the boost function (e.g. via the MAX! Cube) is set so that the display exceeds 999 seconds, the display value switches from seconds to minutes.

Open the window function

The actuator reduces the temperature in the room automatically during ventilation, in order to save on heating costs. During ventilation, the window open symbol () is displayed.
Without MAX! Window Sensor:
A MAX! Radiator Thermostat is able to automatically detect a sharp fall in temperature caused by ventilation (temperature fall detection). The temperature is then reduced to 12’C for 15 minutes (default factory setting).
With MAX! Window Sensor:
When a MAX! A window Sensor is used, the opening and closing of a window is detected at the precise time it occurs. Whilst the window is open, the temperature is reduced to the factory setting of 12’C. When the MAX! Window Sensor detects the closing of the window, all MAX! Radiator Thermostats installed in the room are immediately reset to their original mode.

The open-window temperature and time can be set via the MAX! Software. Temperature fall detection without a MAX! Window Sensor can also be deactivated (by setting the duration to O minutes) via the software.
When a MAX! Window Sensor is taught in, the MAX! The radiator Thermostat does not react to a temperature fall.

The information displayed during normal operation

The current temperature is displayed during normal operation, along with the mode. In the example on the right, the MAX! The 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.

Child-proof lock/Operating block

The operation can be blocked on the device.

To activate/deactivate the operating block, press and immediately release the Auto/Manu and() buttons simultaneously.
Once the block has been activated, “LOG” is displayed for 1 Os. After this, the temperature is displayed again.
To deactivate the block, press both buttons again.

Activating heat pause (to prolong battery life)

Battery life can be prolonged by switching the heating off in summer. To achieve this, the valve is opened fully and the calcification protection function continues to run. To activate this, proceed as follows:

In manual mode (Manu), turn the handwheel clockwise until “On” is displayed.
To end, exit manual mode (Manu) or turn the handwheel anticlockwise.

Activating frost protection operation (radiator switched off)

If the room does not need to be heated, the valve can be closed. The valve is only opened if there is a risk of frost. The calcification protection function continues to run. To activate this, proceed as follows:

In manual mode (Manu), turn the handwheel anticlockwise until “OFF” is displayed.
To end, exit manual mode (Manu) or turn the handwheel clockwise.

Routine descaling

The electronic MAX! Radiator Thermostat has the advantage over mechanical thermostat dials in that it can protect against the threat of valve calcification automatically. To do this, it carries out fully automatic routine descaling once a week. During this brief period, when the valve opens and closes once, the operation is not possible.
Routine descaling is factory-set to run on Saturdays at 11 in the morning. “CAL” is displayed during routine descaling; you can set the day of the week and the time of day via the MAX! Software.
