INSTALLATION AND OPERATING INSTRUCTIONS HR 40 RADIATOR CONTROLLER
BRIEF DESCRIPTION
The HR 40 is an electronic radiator controller with a series of convenient functions:
•You can set your own times and choose from two different setpoint temperatures to set up your own heating programme for each day of the week.
•Self-monitoring features offer protection against calcification and frost, help save energy or indicate when the batteries need to be changed.
•The adjusting ring on the operating unit allows simple changing of the room temperature at any time.
•Installation of the radiator controller is simple and avoids any dirt or water staining.
A setpoint adjuster and power supply unit are also available for the HR 40:
•The HCW 23 K setpoint adjuster can be connected if the mounting site is unfavorable or to make operation more userfriendly. Using a sensor, the setpoint adjuster determines current room temperature which can be adjusted ±12 °C via an adjusting ring. The HCV 23 connecting cable is located next to the setpoint adjuster.
•The HN 40 power supply unit makes the HR 40 independent of batteries.
Scope of supply: Check after unpacking!
Operating unit including batteries (1)
Valve lantern with adjusting ring (2)

INSTALLATION
ONLY 4 STEPS TO COMPLETION...
It only takes a short time to install the HR 40:
•You remove the old thermostat.
•If necessary you install an adapter on the valve.
•You install the valve lantern.
•You attach the operating unit. ... Finished!
Optional:
•You connect the HCW 23 K setpoint adjuster.
•You connect the HN 40 power supply unit.
1. REMOVING THE OLD THERMOSTAT
1.Loosen the mounting of the old thermostat.
2.Pull the thermostat off the valve.
2. INSTALLING THE ADAPTER (OPTIONAL)
The Honeywell-Braukmann, MNG, Heimeier, Junkers,
Landis & Gyr 'Duogyr' valves do not require an adapter. Adapters are available for Oventrop, Herz, Danfoss and Vaillant valves:

1.Select the right adapter from the table.
2.If you need an adapter: open up the adapter and push it onto the valve as far as the stop. Turn it while doing so until you feel it click into place.
3.For the Danfoss RAV adapter: insert the adapter pin in the valve rocker.
4.If provided on the adapter: tighten the adapter with the screw.
3. INSTALLING THE VALVE LANTERN
1. Turn the adjusting ring (3) of |
|
the valve lantern to the left |
1 |
until the nose (1) of the |
|
|
adjusting ring is positioned |
2 |
|
at the stop (2) of the |
||
3 |
||
housing. |
||
|
2. Slide the valve lantern onto the valve or adapter.
The flat area on the valve lantern head must point upwards.
3. Move the knurled nut forwards and tighten it firmly by hand (do not use a tool for this!).
The valve is now open and, with the central heating switched on, the radiator warms through.
Checking the valve lift
The nose of the adjusting ring is positioned at the stop of the housing.
1.Turn the adjusting ring of the valve lantern (1) to the right until
resistance can be felt.
1
The spindle (2) of the valve lantern is now touching the valve pin (3) of the radiator valve (4).
2.Turn the adjusting ring on the valve lantern (1) to the right until the final stop is reached.
The radiator valve is closed. With the central heating switched on, the radiator cools down.

3 4
1
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.
4. INSERTING OR REMOVING THE OPERATING UNIT
1.Turn the retaining bracket on the operating unit until it points upward.
2.Fit the operating unit onto the valve lantern, pushing it on as far as the stop.
The flat surface of the valve lantern must be flush with the operating unit.
3.Turn the retaining bracket on the operating unit until the tip points rearward.
The radiator controller automatically adapts itself to the valve. The display changes during auto-adaptation from 
to aD a. To remove the operating unit, reverse this sequence of operations.
5. CONNECTING THE HCW 23 K SETPOINT
ADJUSTER (OPTIONAL)
Note
A setpoint adjuster can only regulate one HR 40. It is connected via the supplied HCV 23 cable.
The setpoint adjuster determines the current room temperature by means of a sensor.
► Only connect the setpoint adjuster with the power switched off!
Important!
1.Remove the batteries from the HR 40.
2.Use a screwdriver to lever out the cover on the right-hand side of the operating unit.

3.Connect the connecting cable:
see the HCW 23 K installation instructions.
4.Replace the batteries in the HR 40.
5.Adjust the date and time.
6.CONNECTING THE POWER SUPPLY UNIT
(OPTIONAL)
The HR 40 can be supplied with power from the HN 40 power supply unit.
Please refer to the HN 40 documentation for information on the procedure.

HOW TO CHANGE THE ROOM TEMPERATURE
...with the adjusting ring on the operating unit
The adjusting ring on the operating unit can be used to change the setpoint temperature at any time. The setting will apply until the next programmed heating or economy period. When the adjusting ring is turned the display shows the preset setpoint temperature. The adjusting ring does not have a stop. By turning the ring clockwise, the following settings are shown:

...with the HCW 23 K setpoint adjuster
Using the setpoint adjuster, the room temperature can be adjusted by ±12 °C. The radiator controller adjustment range is 8 °C – 28 °C. The 
and 
functions cannot be set.
Note
When you use the setpoint adjuster to adjust the room temperature, the controller's display shows the newly set temperature within 3 minutes. The programmed setpoint temperature remains in the memory.
AUTOMATIC FUNCTIONS
•Window function
If you open a window so that the temperature at the radiator controller drops sharply for more than 3 minutes, the radiator controller closes the radiator valve in order to save energy. The display then shows the message 
.
When the temperature rises again – but no later than after
30 minutes – the radiator controller will resume normal operation.
Note
The window function can be ended at any time by pressing the PROG button or by turning the adjusting ring.
