Application
The Roomtronic HR40 F controls the setpoint temperature* of a room.
It consists of a drive unit and an operating unit and offers a number of
comfortable functions:
•A separate time program can be entered for each weekday.
•The manual adjusting ring at the operating unit allows simple
changing of the room temperature at any time – also in automatic
mode*.
The manual adjusting ring of the drive unit does not have any
function.
•Self-monitoring properties offer protection against calcification,
unintentional setpoint adjustment and frost.
•A flashing display draws the user's attention to the fact that
the batteries have to be changed.
•The Roomtronic changes automatically between summer and
winter times.
•Various valve adapters and a window contact are furthermore
available.

Mounting
Selecting the mounting site
►When selecting the mounting site take into consideration that the
temperature measurement is influenced if the operating unit is
mounted on an outer wall or near heat sources.
Mounting the drive unit
►Turn the radiator on before mounting. The radiator valve must be
open.
HINT: The correct setting of the valve is best checked with the central
heating switched on. If the valve is correctly mounted, the
radiator will become warm.
Separating the drive unit from the valve lantern
►Remove the old radiator
controller, if necessary.
►To open the retainer brack-
et, turn the control knob (1)
so the tip points upwards.

►Separate the drive unit and
valve lantern
Mounting the valve lantern on the radiator valve
The Honeywell-Braukmann, MNG, Heimeier, Junkers,
Landis & Gyr 'Duogyr' valves do not require an adapter. For
adapters for Oventrop-, Danfoss-, Herz- and Vaillant valves
please refer to Page 29.
►Turn the adjusting ring (3) of
the valve lantern to the left,
until the nose (1) of the ad-
justing ring is positioned at
the stop (2) of the housing.

►Slide the valve lantern onto
the heating valve.
►Slide the metal knurled nut
onto the thread of the heat-
ing valve.
►Tighten the metal knurled
nut without using a tool.

Mounting

Checking the valve lift
The nose of the adjusting ring is positioned at the stop of the
housing (Page 6).
►Turn the adjusting ring of
the valve lantern (1) to the
right until some resistance is
felt.
À
The spindle (2) of the valve
lantern is now touching the
valve pin (3) of the radiator
valve (4).

►Turn the adjusting ring of
the valve lantern (1) further
to the right until the final
stop is reached.
The radiator valve is
closed. With the central
heating switched on, the
radiator cools down.
À
The valve lift between the left-hand stop (open) and the right-
hand stop (closed) has to amount to at least ¾ of a rotation.

Mounting
10
Connecting the drive unit and the valve lantern
►To open the retainer bracket,
turn the control knob (1) so
the tip points upwards.
►Slide the housing onto the
valve lantern (2).
►To close the retainer bracket,
turn the control knob so the tip
points sideways.
The housing of the drive unit
and the valve lantern are
connected firmly.
After removing the valve lantern, each time you remount the
lantern, you must carry out a manual or automatic adaptation
(refer to Page 25).

Mounting
11
Mounting the operating unit
►Open the housing of the
operating unit by pressing the
concealed latching nose on the
bottom (1) with a screwdriver
while lifting the cover at the
same time (2).
►Draw and drill the fastening
holes in accordance with the
drilling scheme on Page 28.
►Screw on the operating unit.
Connecting the operating unit and the drive unit
►Insert the plug of the connecting
cable into the socket (1) of the
drive unit housing.
1
►Cut the connecting cable to length so that it reaches from the drive
unit to the operating unit.

Mounting
12
►Insert the open end of the
cable through the recess (1) in
the bottom panel of the
operating unit.
►Connect the cable in ac-
cordance with the adjacent
scheme.
Assignment and conductor col-
ors of the cables:
1 = Black
2 = Red
3 = Green
4 = Yellow
Connection of the window contact HAC 30 is optional (also refer to
Page 3).

Mounting

Inserting batteries into the operating unit
The battery unit of the drive unit does not have any function.
►If necessary, remove any discharged batteries from the operating
unit (please also refer to Setting the date and time, Page 14).
Batteries should not be disposed of in the household garbage.
You may be required by local law to dispose of discharged
batteries in a certain manner.
Always replace both batteries.
Only use 1.5 V mignon batteries of the type LR06.
Ensure that the polarity is correct.
►Insert the batteries into the
battery compartment.
►Position the housing cover
correctly at the top and latch it
into the latching nose on the
housing bottom.
The mounting has been completed.
The automatic adaptation* is activated.

Mounting
14
►Set the date and time once automatic adaptation is complete.
Setting the date and time
The date and time must be set when first configuring the
controller and after each battery change (please also refer to
Page 13).
►Keep the button pressed for at least 2 seconds.
A four-digit number – the year – flashes in the display.
►Turn the adjusting ring until the current year is displayed.
►Press the button.
Two digits flash in the display for the month.
►Turn the adjusting ring until the current month is displayed.
►Press the button.
►Adapt the day, hour and minute by the same method until the current
setpoint temperature is displayed.
The date and time are set.

A rectangle symbolizes one hour of a heating period. A
rectangle is displayed above a heating period of half an hour.
The setpoint temperature* at the Roomtronic can be modified as
follows:
•Manually at the adjusting ring of the operating unit
•By a setpoint modification of the time program at the operating unit
Changing the setpoint temperature at the adjusting ring
►Turn the adjusting ring of the operating unit until the desired setpoint
temperature is displayed.
Values between 8 °C and 28 °C can be set. The adjusting ring does
not have a stop.
Opening or closing the heating valve completely
►Turn the adjusting ring of the operating unit until "OFF" (closed) or
"ON" (opened) is displayed.
Every change in the setpoint temperature remains valid until it
is overwritten by the time program in automatic mode.

Operation
17
Changing the operating modes
The Roomtronic disposes of 3 operating modes:
•Automatic mode* (AUTO)
•Manual mode* (MANU)
•Programming mode* (PROG)
The automatic mode is the standard mode of the Roomtronic.
Temperatures and heating periods are controlled by the time program.
"AUTO" is displayed.
Changing to the manual operating mode
Changes to the setpoint temperature can be carried out at the
adjusting ring of the operating unit in manual mode. The time program
is not active.
►Press the button at the operating unit.
"MANU" is displayed.
Changing to the programming mode
You can adjust the time program to your own requirements in
programming mode. For further information please refer to Chapter
"Adapting" from Page 20 onwards.
►Press the button at the operating unit.
"PROG" is displayed.

Operation

Automatic functions
Window function
If you open a window so that the temperature drops strongly, the
radiator controller closes the radiator valve in order to save energy.
The message is then displayed in the operating unit display.
When the temperature rises again the radiator controller returns to
normal operation, however at the latest after 30 minutes. The optional
window contact HAC 30 allows you to couple the closing of the
heating valve directly to the opening of a window.
Protection against lime
Once a week the drive unit opens and closes the radiator valve
automatically and thus protects it against lime deposits. The message
or is then displayed.
Anti-freeze
If the temperature drops below 6 °C, the drive unit opens the heating
valve until the temperature rises above 8 °C again. The symbol
flashes in the display. The anti-freeze function cannot be de-activated.
