Installation
Step 1: Inserting (replacing) the batteries
• Remove the battery compartment cover
• Insert 2 new LR6 batteries (Mignon/AA) into the battery compartment, ensuring they are the
right way round
• Reattach the battery compartment cover and click into place
New alkaline batteries have a life of approximately two years. A battery symbol ( ) will indicate when the batteries need
to be replaced. after removing the old batteries, please wait approximately 1 minute before inserting the new ones. This
device does not suport operation with rechargeable batteries.
Nevver recharge standard batteries. Doing so will present a risk of explosion.
Do not throw the batteries into a fire.
Do not short-circuit batteries.
Used batteries should not be disposed of with regular domestic waste. Instead, they should be taken to your
local battery diposal point.
Step 2: Settingthe date and time of day
The firmware version number will be displayed briefly once you have inserted/ replaced the batteries and then you will be
automatically prompted to set the date and time of day.
• Use the setting wheel (C) to set the year (B)
• Confirm with OK (D)
• Use the setting wheel (C) to set the month (B)
• Confirm with OK (D)

• Use the setting wheel (C) to set the hour (B)
• Confirm with OK (D)
• Use the setting wheel (C) to set the minute (B)
• Confirm with OK (D)
The motor will start moving back the control pin while the entries are still being made.
• If “InS” is displayed with a rotating „ “ symbol, this indicates that the motor is still moving back. Once the device is
ready for the actuator to be installed on the valve, just “InS” will appear on the display.
• The weekly program and other settings can be customised prior to installation. To do this, press the menu button when
“InS” is shown on the display.
• Once programming is complete, “InS” will reappear on the display and installation (Step 3) can commence.
Step 3: Installing the energy-saving controller
The actuator can be installed on all HERZ TRVs. There is no need to drain away water or fiddle around with the heating system
before doing this.
First, you need to remove the old thermostat dial:
• Turn the thermostat dial anticlockwise as far as it will go.
• Release the thermal ring of the thermostat.
• Remove the thermostat from the valve.
The energy-saving controller can only be installed if “InS” is showing on the display. Following installation, the actuator will
perform an adjustment run so that it can adapt to the valve. During this process, “AdA” will be displayed.
• Place the actuator on the valve.
• Tighten the union nut.
• “InS” will appear on the display, press the OK button.
• The actuator will perform an adjustment run (“AdA” will appear on the display, operation not pos-
sible).
• After that, the actuator will be ready for operation (Auto mode).
If the adjustment run was initiated prior to installation, or if an error message will be displayed (F1, F2, F3); press OK to
move the motor back to the “InS” position.

Setting the weekly program
The weekly program allows you to set up to 3 separate heating periods (7 switching times) for each day of the week. Pro-
gramming is performed in relation to the selected days, for which temperatures must be stored for a period from 00:00 to
23:59.
• Press and hold down the menu button for more than 3 seconds.
• “Pro” will appear on the display.
• Confirm with OK.
• “dAy” will appear on the display. The setting wheel can be used to select an individual day of the
week, all working days, the weekend or the entire week (example shows working days selected).
• Confirm with OK.
• Use the setting wheel to set the first time segment (example shows 0:00 to 6:00).
• Then, select the required temperature for the selected time segment (example shows 17.0°C).
• Confirm with OK.
• Keep repeating this process until you have finished storing temperatures for the period from
0:00 to 23:59.
In Auto mode, the temperature can be modified at any time via the setting wheel. The modified temperature will then be
retained until the next program changeover.
Weekly program: Examples
The energy-saving controller allows you to store up to 3 heating periods (7 switching times) with individual temperature
settings for each day of the week. The factory setting consists of two heating phases (from 6:00 until 9:00 and from 17:00 until
23:00 respectively) for every single day of the week:
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
To represent the switching periods, the display shows bars for every other switching interval. In this example, no bars are
shown for the interval from 0:00 to 6:00. Bars are only shown on the display for the intervals from 6:00 to 9:00 and from 17:00
to 23:00.
If a room also needs to be heated at around noon, the corresponding program might look like this:
Monday bis Sunday
from 00:00 to 06:00 16.0 °C
from 06:00 to 09:00 22.0 °C
from 09:00 to 12:00 17.0 °C
from 12:00 to 14:00 20.0 °C
from 14:00 to 17:30 17.0 °C
from 17:30 to 23:30 21.0 °C
from 23:30 to 23:59 16.0 °C
If you have a home office and only want it to be heated during the day on working days, you can program the following
times:
Monday bis Sunday
from 00:00 to 08:30 17.0 °C
from 08:30 to 17:00 21.0 °C
from 17:00 to 23:59 17.0 °C
Saturday bis Sunday

Information about radio operation
Radio transmission is performed on a non-exclusive transmission path, which means that there is a possibility of interference
occurring. Switching operations, electric motors or faulty electric devices are some of the reasons why interference may oc-
cur. The range of transmission within buildings can deviate greatly from open air distances. Besides the transmitting power
and the reception characteristics of the receiver, environmental influences such as humidity and local structures also play
an important role.

control and implement them. An integrated temperature sensor also detects the current ambient temperature, which can
be seen on the remote control’s display.
The remote control can be used to perform two types of operation:
• Implementing a relative t • emperature change (-/+)
• Switching to the set-back ( ) or comfort temperature ( )
The device may only be operated indoors and must be protected from the effects of damp and dust, as well as solar or heat
radiation.
Using the remote control for any purpose other than that described in this operating manual does not fall within the scope
of intended use and shall invalidate any warranty or liability. This also applies to any conversion or modification work.

Inserting (replacing) batteries
The remote control runs on two LR44 batteries.
• Remove the battery compartment cover.
• Insert two new LR44 batteries in the battery compartment (making sure that you insert them the right
way round).
• Replace the battery compartment cover and latch it into position.
If the remote control is used twice a day, new batteries will have a service life of approximately four years.
A battery symbol ( ) on the display indicates that the batteries need to be replaced.
Never recharge standard batteries. Doing so will present a risk of explosion.
Do not throw batteries into a fire.
Do not short-circuit batteries.
Used batteries should not be disposed of with regular domestic waste. Instead, take them to your local
battery disposal point.
Operation
The remote control features an integrated temperature sensor.
Pressing a button briefly will cause the current actual temperature to appear on the display.
Please note that the detected temperature may be affected by body heat. If you hold the remote control in your hand for
a long period or carry it around in a trouser pocket, the temperature measured by the sensor may be very different to the
room’s actual ambient temperature.
As well as displaying the actual temperature, the remote control can also be used to perform two types of operation:
1) Implementing a relative temperature change:
Here, the room’s current set temperature is increased (e.g. +2.5°C) or decreased (e.g. -1.0°C) by the value set on the remote
control.
• The -/+ buttons are used to increase or decrease the temperature in 0.5°C increments.
• Once the buttons have been pressed as many times as required, there is a short delay before the
temperature change is transmitted and the transmission symbol appears on the display.
• The display switches off after 10 seconds of inactivity.
If the display is still active, changing the temperature again will cause only the new temperature difference 17 to be transmit-
ted. If the display has already switched off after 10 seconds of inactivity, the temperature change starts again from 0°C.
2) Comfort temperature/Set-back temperature
The - buttons are used to activate the comfort/setback temperatures stored in the radio energy-saving controller.
• Pressing the - or - button activates the corresponding setback or comfort temperature.
• Once the button has been pressed, there is a short delay before the information is transmitted
and the transmission symbol appears on the display.
• The display switches off after 10 seconds of inactivity.
After a short delay, five seconds of transmission starts, during which time the transmission symbol is visible on the display.
If a new operation is performed during these five seconds, the change will not be transmitted until the five seconds have
elapsed.
Teaching-in to radio components
In order to enable communication between radio components, the devices have to be taught-in to one another. The remote
control can be taught-in to system components such as a radio energy-saving controller for radiators.
• First of all, the receiver must be set to teach-in mode. For more information on this, refer to the operating manual for the
relevant device.
• Next, the remote control has to transmit a signal in order to be taught-in. To do this, press one of the buttons two or three
times.
• Please note that the batteries must have already been inserted.
• During transmission, the transmission symbol appears on the display.
A remote control can be taught-in to as many actuators as you wish.

Radio shutter (window) contact 1 8250 03
Intended use
This window contact is used to detect when a window is opened. If the window contact is taught-in to a radio energy- saving
controller (see 6), these devices will automatically reduce the temperature in the room during ventilation. Using the automa-
tic temperature reduction function whilst windows are open enables heating costs to be lowered.
The device may only be operated indoors and must be protected from the effects of damp and dust, as well as solar or other
methods of heat radiation. Using the device for any purpose other than what is described in this operating manual does
not fall within the scope of intended use and shall invalidate any warranty or liability. This also applies to any conversion or
modification work. This device is intended for domestic use only.
Overview
1 1 2 2
Magnet Window contact Electronic unit
Preparing for mounting
The window contact consists of two fundamental elem-ents: a magnet (1) and an electronic unit (2).
One of the elements must be mounted on the frame, the other on the window. This ensures that,
when the window is opened, the electronic unit registers that the magnet is no longer in the imme-
diate vicinity and a “window open” signal is transmitted.
Installation location:
• First select the window • that is frequently used for ventilation and which the window contact is to be
attached to.
• The magnet (1) can be installed on the left or right of the electronic unit (2).
• The electronic unit (2) must be attached upright with the release clip (3) at the top.
• The magnet (1) and electronic unit (2) may not be any more than 8 mm (A) apart.
• The magnet (1) and electronic unit (2) must be attached next to one another so that they are level (B).
• The magnet (1) and electronic unit (2) must be positioned so that they are in alignment next to one ano
ther (C).
Mounting
• The magnet (1) and electronic unit (2) may not be any more than 8 mm (A) apart.
• The magnet (1) and electronic unit (2) must be attached next to one another so that they are level (B).
• If necessary, use a pen to mark the bore hole positions (a) for the magnet (1) and electronic unit (2) on
the frame and window.
The magnet (1) and electronic unit (2) can be fastened in two ways:

Adhesive strip method
• This does not damage the door or window in any way.
• Use the adhesive strips supplied.
• Stick the strips on the rear sides of the brackets (1 and 2).
• Then press the brackets onto the frame and window.
Screw method
• If you are working with a hard surface, you should drill the holes marked (a) using a 1.5 mm drill.
• Use the countersunk head screws supplied to fasten the electronic unit (2).
• Once fastened, the magnet (3) can be inserted in the magnet bracket (1). Then place the cap on the
magnet.
Using screws will damage the frame and/or window. For those living in rented accommodation, this could lead to a landlord
making a claim for compensation or holding back a tenant’s deposit.
Inserting (replacing) batteries
The window contact is operated with 2 micro (LR03/AAA) batteries.
• Push the release clip (1) backwards.
• Pull the upper part of the device up and at an angle (2), and remove it from the bracket.
• Insert 2 new micro batteries (LR03/ AAA) in the battery compartment (3) of the upper part (making
sure they are the right way round).
• Place the upper part back onto the bracket, allowing it to latch into place.
The service life of new alkaline batteries is approximately 5 years, based on opening the window twice a day for two hours
at a time. If the LED flashes three times when the window is opened or closed, this indicates that the batteries need to be
replaced.
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.
Used batteries should not be disposed of with regular domestic waste. Instead, they should be taken to
your local battery disposal point.
Teaching-in to radio components
To enable radio components to communicate with one another, they need to be taught-in to one another. The window
contact can be taught-in to system components such as a radio energy-saving controller for radiators.
• The first step is to switch the receiver to teach-in mode. For information on how to do this, please refer to the
operating manual for the relevant device.
• Following this, the window contact needs to transmit a signal for teaching-in purposes. To initiate this, open or close
the window.
• If the window contact has not yet been installed, you can simply separate the magnet and electronic unit or rest them
against one another. However, please note that the batteries must already have been inserted in order to do this.
• When a signal is transmitted, the window contact LED lights up.
A window contact can be taught-in to any number of actuators.
LED flashing sequences & transmission behaviour
The LED’s flashing sequences have different meanings:
Flashing
sequence Meaning
1x flash Contact/window closed
2x flashes Contact/window open
3x flashes Replace batteries
If, whilst a signal is being transmitted (after the window has been opened or closed), the window contact detects that the
battery power is too low, the LED will emit the “replace batteries” flashing sequence once the signal has finished transmit-
ting.
After a window has opened or closed, the window contact transmits a signal for 5 seconds. Any further changes that are at-
tempted while the signal is being transmitted will not provoke a response. However, if the position has been changed during
this time, the new status will be transmitted directly afterwards and indicated by an LED flashing sequence.

USB programming stick 1 8250 04
Intended use
The USB programming stick is used to program system components such as radio energy-saving controllers. The USB stick
does not have any controls and must be used in conjunction with the associated PC software. The device may only be ope-
rated indoors and must be protected from the effects of damp and dust, as well as solar or heat radiation. Using the device
for any purpose other than that described in this operating manual does not fall within the scope of intended use and shall
invalidate any warranty and exempt HERZ from any liability. This also applies to any conversion or modification work. The
device is intended for private use only.
Operation
Programming settings are made using the associated PC software. For more information see Section “PC software”. The PC
software uses the USB programming stick to send the weekly programme, along with the date and time, to devices that are
ready to receive. For more information see Section “Radio transmission of programming settings”.
PC-Software
The PC software for the USB programming stick can be downloaded from www.herz.eu. The corresponding file can be
found in the “Download” area. Follow the on-screen instructions when downloading the PC software.
Radio transmission of programming settings
So that the USB programming stick can send data to system components such as radio energy-saving controllers, these
components must first of all be set to teachin mode.
• The USB programming stick must be plugged into the PC’s USB port.
• The PC software must be running on the PC and programming must be complete.
• For transmission, the receivermust be set to teach-in mode. For more information on this, refer to the operating manual
for the relevant device.
• The USB programming stick can now send data to the devices that are ready to receive. To start the transmission
process, activate the transmission function in the PC software.
The USB programming stick does not remain permanently taught–in on the devices to be programmed.
If the USB programming stick is being used to send a weekly programme, all devices that are ready to receive will receive
the programme accordingly. An unlimited number of receivers can be programmed.
When being put into operation for the first time, a radio energy-saving controller can be switched to teach-in mode im-

Make sure that the receivers are located in the wireless range of the USB programming stick.
Receive mode:
The receiving devices must be set to teach-in mode during transmission.
