Expert electricians only may open this device in due compliance with the
wiring diagram shown in the housing cover / on the housing / represented in
the corresponding operating instructions. All expert electricians charged
with the execution of such works must comply with the relevant safety regu­lations currently operative and in force. Caution: The operation of the con­troller in the vicinity of other devices that do not comply with the EMC direc­tives may affect its functions. The company charged with the installation of
the device must, after the completion of the installation works, instruct the
user of the control system into its functions and in how to operate it correctly.
These operating instructions must be kept at a place that can be accessed
freely by the operating and/or servicing personnel in charge.

1. Safety information

5

The controller described in these instructions is provided for flush installa­tion and has been specially devised for the time-dependent control of the
temperatures in individual rooms or of the temperatures produced by elec­tric or warm-water heating systems (systems with normally closed valve
actuators). The device can be used as floor or as room temperature controller
with additional floor temperature controller function. Operation in emergency
mode is triggered if the internal or external sensor is defective. The same
applies if no sensor has been connected when using the device as room
temperature controller with additional floor monitoring function and also
when using it as floor temperature controller. An error message appears on
the display and an indicator lamp starts blinking red to indicate this condi­tion. During operation in emergency mode a fixed 30% duty cycle is being
maintained to prevent the related room from cooling down thoroughly and
protect it against frost damage. The activation time divides into a 3-minute
ACTIVE and a 7-minute OFF time.

2. Application / functional description / emergency operation

6

The device is equipped with 4 touch keys, all of which have been marked by
the symbol . The functions allocated to them may vary in dependence on
the operation requirements. The related function is being indicated on the
display which exists above the corresponding keys. A special protective
function helps prevent an inadvertent activation of the touch keys. This
function is activated 20 seconds after any of the touch keys has last been
activated. Actuating any of the touch keys deactivates this function again for
2 seconds.

– Comfort mode, permanently
– ECO mode, permanently
– Operating mode “OFF”

In “OFF” mode, the controller activates the heating when underrunning a
temperature level of approx. 5°C and deactivates the operations when
exceeding a temperature level of approx. 6°C. This antifreezing function
helps prevent rooms from cooling down thoroughly and protects against the
occurrence of frost damage.

The following functions are available:

1. Keylock

The keylock is activated 2 minutes after actuating any of the touch keys. The
key icon appears on the display to indicate this locked state. The touch keys
can be reactivated by actuating and holding any of the keys depressed for
10 seconds.

2. Automatic change between daylight saving and standard time

The harmonised daylight saving time in the European Union takes effect as
of the last Sunday in March, i.e. as of 2.00 o’clock a.m. CET and lasts until
to 3.00 o’clock a.m. on the last Sunday in October (CEST) each year (direc­tive 2000/84/EG of the European Council and Parliament). The temperature
controller changes the time all automatically at these dates. The automatic
change between daylight saving and standard time can also be deactivated
to enable the changing of the time at other dates or to meet the time condi­tions in other regions.

3. Valve and pump protection function

The valve and pump protection function serves to prevent the valve seat
and/or the pump(s) from corroding up during longer stop times. If using the
device for the control of warm-water heating systems, activating the valve
protection function is recommended. After activation of the valve and pump
protection function, the controller actuates the valve(s) or triggers a heating
pump every Monday at 11.00 o’clock a.m. over a 5 minute time period. The

5.8 Settings

32

valve and pump protection function is rendered active only if no heating
operations were executed within the last week. Unnecessary heating during
the heating season is thus avoided, thereby leaving the control system unaf­fected.

4. Self-learning function

The self-learning function serves for the autonomous attaining of the comfort
temperature at a preset time. The antedated point at which the system swit­ches from ECO over to comfort temperature sets itself all autonomously.
Depending on the calorific output and the prevailing outside temperature, the
heating time will vary.

5. Backlighting of the display

The length of time during which the display backlight is on, can be selected
as follows:

1. Backlight during operation plus 10 seconds after the last actuation of any
of the touch keys;

2. Additional backlight during operating times in comfort and also in party
mode;

3. Permanent backlight.

6. Display indications

If configuring the device for use as floor temperature controller, only the time
indication is active.
If the HTRRUu 210.021 has not been configured for use as floor temperature
controller, the operator can select between the following indications:

1. Time;

2. Temperature;

3. Time & temperature (alternating).

33

6. Experts menu

Depressing the right touch key and keeping it depressed for 10 seconds after
accessing the “settings” submenu (see page 11) from the main menu, enables to
call the experts menu.

Caution! This menu enables to make control settings that may only be perfor­med by a qualified heating specialist or an expert electrician. The settings made
while operating in this mode cannot be reset via the reset function and have to
be made knowingly, therefore. Clear proof that such settings have been made by
one person only is thus ensured.

The following settings are available:

1. Selection of controller configuragtion variants

The following controller configuration variants can be selected: “Room tempera­ture controller”, “Room temperature controller with floor temperature controller
function” or “Floor temperature controller”.

2. Language

The operator can select between the following languages: Czech, Dutch, English,
French, German Polish and Russian.

3. Measuring correction

The measured temperature value can, in dependence on the related configura­tion, be adjusted with regard to each individual sensor within a range from -5K to
+5K at 0.1K steps. At the same time, the uncorrected value measured by the rela­ted sensor is being indicated on the display (factory setting 0.0).

4. Maximum temperature(setting possible only when using the device as room

temperature controller with floor temperature controller function or as floor tem­perature controller)

34

The maximum temperature measured by the floor temperature can be defined
within a range from 15 to 42°C. Damages to the floor in consequence of exces­sive temperatures can thus be prevented (factory setting 42°C).

5. Entry of the connected load (entry possible only when using the device as

room temperature controller with floor temperature controller function or as floor
temperature controller)
In order to allow to compensate the self heating of the HTRRUu, the power con­sumption of the connected consumer needs to be entered. The power consumed
in consequence of the connected heating load is indicated in kW and can be
adjusted within a range from 0.1 to 2.3. With intermediate values, the nearest
lower value needs to be set. If actuating valves instead of controlling an electric
heating system, the low power consumption of these valves can be neglected,
so that no changes need to be made (factory setting 0.1).

6. Control methods (available only when using the device as room temperature

controller with floor temperature controller function or as floor temperature con­troller)
PI-PWM method (proportional–integral), recommended for the control of warm­water and floor heating systems.
Two-point method (hysteresis), recommended for the control of electric direct or
storage heating systems (factory setting: two-point method).

7. External sensor (connection possible only when using the device as room

temperature controller with floor temperature controller function or as floor tem­perature controller)
The HTRRUu210.021 allows to connect external temperature sensors (NTC) with
resistance values of 2, 12, 15 or 33kΩ. The actually used temperature sensor
needs to be selected here (factory setting 2kΩ).

8. Reset function

Actuating this function resets all settings made outside of the experts menu
(except for time and date) to the condition as delivered.

35

7. Mounting / connection

The device equipped with the 50 x 50 mm housing cover can be integrated
into almost all currently available flush switch installation frame systems
when using DIN 49075 compliant intermediate frames. The device equip­ped with the 55 x 55 mm housing is, likewise, suited for use with different
frame systems. If using multiple frames, the controller needs always to be
mounted in the lowest position. The controller is determined for installation
in an UP box and may not be exposed to any heat or cold sources. The con­troller must not be exposed to direct cold or heat sources. Furthermore, care
must be taken to ensure that the device is not exposed to the influence of
foreign heat or cold sources that warm or cool the device at its back
(through air flows in cavity walls or the temperatures radiated by ascending
pipelines, f. ex.). The controller should be mounted on the wallpaper / the
wall covering.

Caution: Prior to performing any installation works, always make sure
to disconnect the mains voltage at all poles! The electrical connection is

to be realised as shown in the
connection diagram in section 8
herein. The plug-type terminals
can comfortably be pre-wired for
this purpose and connected to the
controller while installing it into
the under plaster box. The ope­ning of the device is realised as
described in the drawing below by
holding the housing cover at the
top and bottom and pulling it
open. After first start-up, the
experts menu items 6.2,

“Language” and 6.1, “Selection of
controller configuration variants”, are being called up all automatically. The
device will only be operable after having made correct entries.

Important Notice!

The single wires of both the power supply cable and the sensor line need
to protected against shifting by securing them with one cable tie each as
shown here below. In so doing, care is to be taken to ensure that the
distance between cable tie and power supply- or sensor line terminal
respectively, is always kept as short as possible (max. 15 mm).
