4. Function
With the Radiator Thermostat Model N you can conveniently regulate the room
temperature. Thanks to pre-programmed or individually tailored heating and cool-
ing 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.

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.

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 with-
out 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 Danfoss
valve bodies have elongated notches (K) around their circumference, which also en-
sure 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!
