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.

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.
