required. You merely require a fl at head or Phillips head
screwdriver for installation.
The radiator thermostat is equipped with a universal
cap nut
(M30x1.5 mm)
and thus fi ts the following
valves without an adapter:
• Heimeier
• MNG
• Junkers
• Honywell-Braukmann
• Landis/&Gyr (Duodyr)
• Oventrop
• Schlösser
• Comap
• Valf Sanayii
• Mertik Maxitrol
• Watts
• Wingenroth (Wirofl ex)
• R.B.M
• Tiemme
• Jaga
• Siemens
• Idmar
Radiator valve Danfoss adapter selection
Adapters are required for several valve types which is why
the delivery includes 3 adapters, for installing the wireless
radiator thermostat on Danfoss RA, Danfoss RAV
and Danfoss RAVL valve models.
• Prior to installation, select the correct adapter
based on the table.
• If an adapter is required, select the correct adapter
from the table, push the adapter onto the valve
and turn it until you feel it lock into place.
• If the adapter is equipped with one, tighten
the screw on the adapter.

Valve protection
If the valve is not completely opened once over the
course of a week, the radiator thermostat automatically
opens the valve briefl y on Sundays to ensure it doesn't
stick.
Frost protection
If the ambient temperature drops below 4 °C,
the radiator thermostat opens the heater valve until
the room temperature reaches 6 °C. This prevents the
radiator from freezing.
Spent batteries
If the symbol for empty batteries appears on
the display, the battery on the radiator thermostat must
be replaced as quickly as possible. When the symbol
appears for the fi rst time, the battery will last
approx. 1.5 weeks. After removing the battery, the radiator
thermostat will store the data for approx. 5 minutes so
the battery can be replaced. The battery status of the
remote control can be determined based on the LED.
LCD display and buttons
Attention!
This function is only active in automatic mode.
Notes on wireless operation
The wireless transmission is established
on a non-exclusive 433 MHz transmission
carrier which is why interference cannot be excluded.
The range in buildings can severely vary from use in
the open.
