Universal Controller HRT 6150
1. Description of the functions
The HRT 6150 is a universal temperature controller with timer function.
It permits the specification of one or two warm phases per day, e.g.
between 6 a.m. and 10 p.m. in the living room or from 6 to 9 a.m. and
5 to 9 p.m. for a bathroom. The temperature is lowered between the
specified times.
The amount by which the controller lowers the target room temperature
is programmed once.
The unit can be used as a
Room temperature controller
The unit controls the room temperature to achieve the desired target
temperature in the range between 5° and 30°C. The current room
temperature is displayed.
Floor temperature controller
The unit controls the floor temperature to achieve the desired target
temperature in the range between 10° and 40°C. The current room
temperature is displayed.
Room temperature controller with monitoring function
The unit controls the room temperature to achieve the desired target
temperature in the range between 5° and 30°C. The current room
temperature is displayed. In addition, the floor temperature is
monitored. The maximum floor temperature is programmed once.
This operating mode can be selected in the setup menu.
The unit is factory-set as a floor temperature controller.
2. Connection / commissioning
ATTENTION: Work on the 230V mains must only be performed by
authorised electricians. When the controller is connected to the mains,
the relevant safety regulations of the VDE and the local utility companies
are to be observed.

Installation: The temperature controller is to be mounted into a
standard flush-type box Ø 55 mm (acc. to DIN 49073, Part 1). If
additional intermediate terminals are used, we recommend use of a
deep switch box. The connections are to be made in accordance with
the wiring diagram (see above). The connecting cables must be straight
with approx. 5 mm insulation removed; mounting height approx. 1.5 m
above the floor.
Attention: Align the mounting ring on the wallpaper and mount the
controller on the switch box using self-tapping screws for flush-type
boxes. Then fit the frame onto the mounted box.
Attention: Before pressing on the cover, make sure that the internal
sensor (bottom left) points downwards at an angle. The sensor should
not be in contact with the controller housing.
The floor temperature sensor is to be placed in a protective tube lying
centrally between the heating pads and in the same plane as the pads.
The sensor cable must be routed in a separate protective tube (never
together with mains-voltage cables).
Attention: In case of error, the sensor cable may carry mains voltage!
3. Overview of the display
Turning on the unit for the first time:
When the controller is turned on for the first time, all
elements of the display are visible briefly.
After 5 seconds
The current software version of the controller is
displayed.
After 5 seconds
The figures "88:88" are displayed, since time of the
day, date and day of the week are not yet
programmed. Basic programming (Point 6) must be
performed for the unit.

4. Standard display
Use the M key to select the operating mode.
▪ AUTOMATIC mode
The controller is active during the specified warm
phases , outside the warm phases , the
temperature is reduced by the specified amount.
▪ MANUAL mode
The controller regulates constantly to the specified
target temperature.
▪ OFF
The controller regulates constantly to the specified
frost protection temperature.
5. Setting the setpoint

6. Basic programming
Pressing the C key briefly opens the controller settings. To switch
between the individual items, use the C key; to make changes, use the
+ and – keys.
The programming can be quit at any time by pressing the M key, but is
also quit automatically if no key is pressed for 10 seconds. The changed
values are accepted automatically.
Press the C key briefly once.
Setting the time
A clock symbol is displayed; use the +/-keys to set
the time.
Press the C key briefly once.
- with automatic setting of daylight saving time
Set the calendar year
A "Y" is displayed;
use the +/-keys to set the calendar year.
Press the C key briefly once.
Set the month / day
A "D" is displayed;
use the +/-keys to set the date.
Large digits: Month / small digits: Day
- without automatic setting of daylight saving time
Set the day of the week
A number for the day of the week is displayed;
use the +/-keys to set the day.
1 = Monday.... 7 = Sunday
Press the C key briefly once.
Automatic daylight saving can be turned on / off in the display menu.
Setting the temperature reduction
A moon and a thermometer symbol are displayed;
use the +/-keys to set the temperature by which the
temperature is to be reduced between the warm
phases.
Setting range: 3° - 15° C
Factory setting: 3°
Press the C key briefly once.
Setting the monitor temperature
(only in the "Room controller with monitoring " mode)
A detector symbol is displayed;

Setting range: 20° ... 40° C
Factory setting: 28°
Press the C key briefly once.
Programming the warm phases
The controller can be operated in either the block or single-day mode. If
block mode is programmed, the same timer program is executed on
each of the working days 1 to 5 (1 = Monday, 2 = Tuesday, etc., see
digits in the top line of the display) and thus only needs to be entered
only once. A different timer program can be entered for the weekends -
days 6 and 7 (Saturday and Sunday). The possibility to use simply two
blocks saves a great deal of programming work.
Factory setting:
1st warm phase: 6 a.m. - 10 p.m.
2nd warm phase: Not programmed
The individual programming modes are switched in the display menu.

The days 1 - 5 are shown on the display together with a
sun symbol with index 1.
Press the C key briefly once.
End of the 1st warm phase on weekdays:
The days 1 - 5 are shown on the display together with a
moon symbol with index 1.

a sun symbol with index 2.
Press the C key briefly once.
End of the 2nd warm phase on weekends:
The days 6 and 7 are shown on the display together with
a moon symbol with index 2.
Programming example for the single-day mode
Single-day programming is performed in the same way as block
programming. The individual weekdays are shown as numerals in the top
line of the display.

A reset is initiated by briefly pressing the recessed key. The
programmed values are maintained, but time of day and date or day of
the week must be set anew.
11. Factory settings
Simultaneously pressing the Mand C keys for at least 5 seconds
resets the controller to the initial state and restores the factory settings.
The controller is delivered with the following factory settings:
Controller type: 2 (floor temperature controller)
Sensor type: 1 (HRT standard sensor)
Temperature reduction: 3°
Monitor temperature: 28°
Frost protection temperature: 5°
1st warm phase: 6 a.m. - 10 p.m.
2nd warm phase: Not programmed
Programming type: Block programming
Display: Clock + temperature
Automatic daylight saving time: ON
Temperature calibration: 0.0°
Switching cycle: 0 minutes
Cooling controller function: OFF
Valve protection function: OFF
Teach-in function: OFF
2nd temperature reduction OFF
12. Mains power failure
Up to eight hours of mains power failure are compensated. If the power
failure lasts longer, only the clock and date must be set anew; the
remaining settings are maintained.
Any deliberately initiated daily shutdowns (e.g. off-periods of the utility
company) can cause damage to the memory. This is not considered use
according to the intended purpose and results in exclusion of the
warranty.
13. Special function
The controller can be used as a pilot controller (upon request). To this end,
it connects 230V to terminal "TA" (max. load capacity: 0.2A) when in
temperature reduction mode. It is possible to connect satellite controllers
without timer (including bimetal controllers) to the TA terminal; they then
operate simultaneously with the pilot controller in temperature reduction
mode.
14. Troubleshooting
Diagnosis Possible cause / remedy
Heating does not work - Connect / check mains voltage
Display:
- No display Mains power failure
- Er 0 Incorrect input
- Er 1 Room sensor defective

Exclusion: The liability for defects does not cover natural wear or
transport damage; likewise not damage due to non-observance of the
installation instructions, inappropriate installation and use not according to
