2. Brief description
HR92 is an electronic radiator controller with a modern
design. Because of the wireless communication with
a frequency of 868 MHz the controller can be easily
integrated in heating systems such as evohome to
control the room temperature.
User-friendly
• Large adjustable display with backlight.
• Display of information in the display using symbols
and text.
• Parameters can be set individually.
• Manual temperature modification (effective until the
next switching point) possible at any time.
Mounting
• The radiator controller fits on the most common
radiator valves of the type M30x1.5.
• Further adapters are available as accessories.
• An external window contact can be connected
optionally.
Energy saving features
• With the window function, the radiator valve is closed
when ventilating the room.

Inserting/changing batteries
The radiator controller is set for the following battery
type:
• 2 alkaline cells 1.5 V; type LR6, AA, AM3
You can instead use the following batteries or
accumulator cells:
• Lithium 1.5 V; type LR6, AA, AM3
• NiMH 1.2 V; type LR6, AA, AM3
• If lithium or NiMH batteries are used, Parameter 9
i
has to be adapted, see Section 5.
• Always change batteries in pairs.

WARNING
f Never short-circuit batteries or throw them
into fire.
f Dispose of used batteries ecologically.
Establishing radio connection
The radiator controller HR92 communicates with the
central operating device by radio using the frequency
of 868 MHz. To this purpose the connection between
the HR92 and the central operating device has to be
established first. This process is called BINDING. In the
case of preconfigured devices binding has already been
carried out in the factory.
If binding has not yet been carried out,
i
displayed after has been pressed.
Binding must first be activated at the HR92 so that the
radio signal can be received. Subsequently binding has
to be activated at the central operating device.

1. Pull off the adjustment dial. To do so, start at the notch
on the bottom of the device.
2. If used, unscrew any fastening screws from the

3. Release the lock and fold out battery spring.
The battery compartment is now accessible.
4. Insert the batteries.
Ensure that the polarity "+" and "–" is correct.
5. Fold down the battery spring and latch it in.
