4. Function

With the Radiator Thermostat Model N you can conveniently regulate the room tem-

perature. Thanks to pre-programmed or individually tailored heating and cooling 

phases the desired temperature can be comfortably adjusted. The device moves 

a valve to control the flow of heat to the radiator. The radiator thermostat fits to all 

common radiator valves and is easy to mount - without having to drain any water 

or intervene in the heating system. The additional boost function enables quick, 

short-term radiator heating by opening the valve for 5 minutes. This immediately 

brings a comfortable warmth to the room.

5. Safety instructions

The device is not a toy; do not allow children to play with it.

Do not leave packaging material lying around, as it can be dangerous in the 

hands of a child.

Do not open the device: it does not contain any components that need to be 

serviced by the user. In the event of an error, please return the device to our 

service department.

6. Disposal instructions

Do not dispose of the device with regular domestic waste.

Electronic devices must be disposed of in accordance with the Waste Elec-

trical and Electronic Equipment Directive via local disposal points for elec-

tronic waste.

The CE sign is a free trading sign addressed exclusively to the authorities 

and does not include any warranty of any properties.

Used batteries should not be disposed of with regular domestic waste! 

Instead, take them to your local battery disposal point.

7. Inserting (replacing) batteries

In the initial state, the batteries are already inserted. Simply remove the insu-

lation 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) batteries in the battery 

compartment, making sure they are the right way round.

• 

Reattach the battery compartment cover and latch it into 

place.

The service life of new alkaline batteries is approximate-

ly 3 years. A battery symbol (

) on the display indicates that the batteries 

need to be replaced. After removing the empty batteries, wait approx. 1 min-

ute before inserting the new ones. This device does not support operation 

with rechargeable batteries.

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.

8. Set date and time

After inserting batteries, the date and time is automatically requested after a brief 

display of the firmware version number and short motor run ("INS").

• 

Set the year, month, day, hour and minute with the handwheel and confirm by 

pressing the handwheel shortly (

F

).

You can adjust the time and date in the menu under "DAT".

The motor moves the control pin backwards during the setting of date and time.

• 

If "InS" and the rotating activity symbol " " are displayed, the motor still revers

-

es. When only „INS“ is shown in the display, the radiator thermostat can be in-

stalled on the valve.

• 

The week program and other settings can be adjusted before installation. Press 

the Mode/Menu button for this, while „INS“ is shown in the display. Press the 

Mode/Menu button for this, while „INS“ is shown in the display. You will find fur

-

ther information in chapter "11. Setting week program“.

• 

After the programming has been completed, „INS“ is shown again in the display 

and installation can take place.

9. Installation on the radiator

The 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 valves of the most popular manufacturers with a thread 

size of M30 x 1.5 mm.

By means of the adapter in the delivery, the device can be installed on radiator 

valves of type Danfoss RA.

• 

Rotate the thermostat dial to the maximum value (anti-clockwise). The thermostat 

dial then no longer presses against the valve spindle, making it easier to remove.

• 

Now remove the thermostat dial. If required, fix the supplied adapter. Afterwards, 

the adapting run can be initiated (see chapter „10. Adapting run“).

9.1. Adapter for Danfoss

The provided adapter (RA) is required for installation on Danfoss valves. The Dan-

foss valve bodies have elongated notches (

K

) around their circumference, which 

also ensure that the adapter is properly seated when it snaps on.

If required, place the provided support ring (

I

) into the flange before mounting 

the radiator thermostat.

During installation, please ensure that the pins inside the adapter (

J

) are lined 

up with the notches (

K

) on the valve. Ensure that the adapter is properly clipped 

on.

Take care during installation that you do not trap your fingers between the two 

halves of the adapter!

I

10. Adapting run

After the batteries have been inserted the motor reserves. Meanwhile, the date, „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.

• 

Tighten the union nut.

• 

Press the handwheel shortly when "InS" is displayed.

Now the radiator thermostat performs an adapting run. "AdA" and the activity sym

-

bol ( ) are displayed; during this time, operation is not possible.

If the adapting run has been initiated prior to mounting, please press the hand-

wheel shorty and the motor reserves to the "INS" position. If an error mes

-

sage (F1, F2, F3) is displayed, the motor similarly travels back to the „INS“ 

position.

11. Setting the week program

In the week program, for each weekday up to 3 heating phases (7 change settings) 

can be set separately. The programming is carried out for the selected days, whereby 

temperature settings have to be set for the entire period between 00:00 and 23:59.

• 

Press the Mode/Menu button for at least 3 seconds. „PRO“ appears in the dis-

play. Confirm by pressing the handwheel shortly.

period from 0:00 to 23:59 have been stored.

• 

If all 7 switching time points have been allocated, 23:59 is displayed as the final 

switching point to be confirmed.

In auto mode, the temperature can be changed at any time using the hand-

wheel. The modified temperature will then remain the same until the next point 

at which the program changes.

11.1 Week program: Example

For each day of the week up to 3 heating phases (7 change settings) with individual 

temperature settings can be saved with the radiator thermostat. 

Two heating phases from 6:00 to 9:00 and from 17:00 to 23:00 for all weekdays 

alike are saved as factory settings:

from 00:00 

to 

06:00   17.0 °C 

from 06:00 

to 

09:00   21.0 °C

from 09:00 

to 

17:00   17.0 °C

from 17:00  

to 

23:00   21.0 °C

from 23:00 

to 

23:59   17.0 °C

Bars for switching time periods for every second time interval are shown in 

the display. In this example, bars are displayed only for the intervals 06:00 to 

09:00 h and 17:00 to 23:00 h.

12. Display content in normal mode

Switching time periods, operating mode, setpoint temperature and week day are 

displayed in normal mode.
