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 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

► 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 adjusting 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 heating 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.

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.

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.
