Nighttime temperature
The nighttime temperature is adjusted
with the lower adjustment button [1].
It is displayed in the right-hand half of
the display as an absolute value. The
unit displays the actual temperature
again automatically three seconds after
the last rotation of the button.
The current setpoint can be requested by
pressing the SET program key.
The actual temperature is displayed
again automatically after three seconds.
Daytime temperature
The desired temperature (5 to 40°C)
is adjusted with the upper adjustment
button [2].
This is displayed in the right-hand half
of the display in place of the actual
temperature.
The unit displays the actual temperature
again automatically three seconds after
the last rotation of the button.
Holiday program
The holiday program can be set to
between 5°C and 15°C in the control
parameters menu.
The temperature can be selected by
simultaneously pressing on the two
program keys and .
If the holiday program is activated in
cooling mode, an internal, fixed set
target temperature of 45°C is used for
the control, which normally prevents
the connected cooling device being
activated.
The mode is indicated via an indicator
[6] on the left edge of the display
depending on the selected basic function
"Heating or Cooling".
Display with switched "Heat" output
Display with switched "Cool" output
The changeover of the "Heat/Cool"
functions is implemented manually in
"H C" operating mode.
In "Heat" mode, the switching function
is displayed on the left-hand side of
the display with an upwards pointing
arrow () and in "Cool" mode, with a
downwards pointing arrow ().

NOTE
A change in the daytime
temperature also results in the
nighttime temperature being
changed by the same amount
because the nighttime temperature
is coupled to the daytime
temperature. Conversely, a change
to the nighttime temperature
does not necessitate a change in
the daytime temperature (see the
example on page 15 too).

Hand key
The key is used to modify the
current temperature level in automatic
operation.
The selected temperature level is
displayed on the right-hand side of the
display with the indicators.
This function is deleted with the next
program point.
Off
The controller is switched off by
simultaneously pressing the ¹and 
program keys.
The operating mode is no longer
displayed on the right-hand side of the
display. The unit continues to record the
actual temperature, however the switch
relay for temperature regulation is no
longer activated.
Frost protection is no longer available.
CAUTION
The holiday program is not
available in cooling mode.
NOTE
Frost protection is always assured
when the unit is active as the
temperatures cannot be set lower
than 5°C.
Reset key
Two different resets are possible:
1. Start-up reset:
The Reset [4] key allows the unit to be
started up again in the event of a failure
due to a malfunction.
The program and parameter settings are
retained.
The clock will need to be set again.
2. Global reset:
In order to force the unit to start up with
factory settings, the –and PROG keys in
addition to RESET [4] must be pressed.
After releasing the RESET key, the –and
PROG keys must continue to be pressed
until the version number (Id:00...)
appears on the display.
Any previously entered individual
time program and parameter set-
tings will be lost.
NOTE
NOTE
In the event that a temperature
probe is faulty or missing, "FA IL"
appears on the display.

The clock is a weekly timer with approx.
4 hours of power reserve.
On initial commissioning or following
a reset, a flashing zero appears on the
display.
The time can be set by pressing the ¹
key for 3 seconds or following a restart
after a reset.
The flashing values can be modified with
the + and – keys.
The SET key takes you to the next
setting (Hours -> Minutes -> Year ->
Month -> Day).
After confirming the minutes with the
SET key, the clock is started with to-the-
second accuracy.
After confirming the day, the unit returns
to the operating mode from which the
"Set time" menu was called.
The time program can be modified by
briefly pressing the PROG key.
16 program spaces are available.
These allow up to 112 switching times to
be programmed.
Program point number P01 appears
in the display along with the
associated time, the weekday and
the corresponding temperature level
(daytime temperature, nighttime
temperature or holiday temperature)
shown by the indicator on the right.
The flashing program point P01 can be
changed with the +and –keys (P01 - P16).
The SET key takes you to the settings
for the switch-on and switch-off times
(flashing clock).
Pressing the +and –keys modifies the
switching time point of the clock in
10 minute increments.
The clock changes automatically
between summer/winter time.

Pressing the SET key opens the settings
for the days of the week (flashing day
indicators).
The following selection options are
available:
MO - SU / MO - SA / MO - FR /
SA - SU, or each individual day of the
week.
The selections are madeby pressing the
+and –keys.
Pressing the SET key again opens the
settings for the desired temperature
values (flashing indicators in front of the
respective temperature mode).
Pressing the +and –keys modifies the
temperature mode.
The desired temperature settings for
daytime and nighttime are confirmed
with the adjustment buttons [1 and 2].
After pressing the PROG key with
flashing program point number, the unit
returns to the operating mode from
which the "Modify time program" was
called.
Ineffective program points are marked
with ––:–– instead of the time.

following meanings:
Pressing the PROG key for 6 seconds
opens a menu in which the different
basic functions can be set.
The function is displayed in the left-hand
half of the display and the corresponding
value or status in the right-hand half of
the display.
Pressing the PROG key for 3 seconds
opens a menu in which the different
regulation parameters can be set.
The parameter is displayed in the
left-hand half of the display and the
corresponding value or status in the
right-hand half of the display.
The value can be modified with the
+and –keys.
The SET key moves to the next
parameter.
Confirming the last parameter with the

0.0 K ±3.0 K
SEnS (sensor calibration display)
Stabilised temperature values must be
available for sensor calibration. In addition,
sensor calibration must be performed at a
usual room temperature of approx. 20°C.
In order to perform correct temperature
calibration, the actual temperature
displayed on the unit and the temperature
at the sensor (to be measured with
a suitable temperature measuring
instrument) must be known.
The difference between these two values
can be set within ±3.0 K limits under the
SEnS menu item.
Example:
20.7°C is shown on the unit display.
The temperature measuring instrument
shows 19.9°C as the temperature at the
sensor.
– 0.8 must therefore be set under the SEnS
menu item.
NOTE
The accuracy of temperature
recording is dependent on the
length and cross-section of the lines
(see table on page 14).

results in the corresponding parameters
from the basic settings being used
for calculation. These settings are
shown under the "Setting the control

Assembly
The electronic temperature controller
is suitable for wall mounting with a
surface-mounted cable inlet.
The external temperature probe
must, where possible, be fitted
to an internal wall around 1.5 m
above the floor.
NOTE The external temperature probe
must be installed such that it
can record the average room
temperature. Draught and proximity
to windows, doors and heat
sources, etc. must be avoided.
NOTE
Do not fit probe next to windows!Do not fit probe in hot air flow!

■ Use probe lines in accordance with
the requirements and note the
maximum line lengths and requisite
minimum cross sections
Maximum line

30 m 0.50 mm²
45 m 0.75 mm²
60 m 1.00 mm²
90 m 1.50 mm²
■ De-energise all live lines before
working on the unit
■ Connections must be made in
accordance with the circuit diagram
on page 18
■ The unit is only approved for
connection to fixed lines
■ When installing the unit, it must be
ensured that lines carrying mains
electricity, such as the mains supply
and relay connection lines, cannot
come into contact with low-voltage
lines such as probe lines (minimum
clearance 4 mm for lines with basic
insulation)
■ The requirements of EN 60730
Part 1 must be adhered to to
ensure adequate protection against
connecting conductors self-loosening.
This may be achieved by securing the
lines with suitable cable ties
■ VDE 0100, EN 60730 Part 1 and the
regulations of the local EVU must also
be observed
■ In the event that the unit does not
Errors on connection can cause
damage to the unit! No liability
will be assumed for damage caused
by incorrect connection and/or
improper operation!
CAUTION
CAUTION
For the avoidance of malfunctions,
the external probe lines must not
be routed together with other live
lines. Observe a minimum clearance
of 4 mm when using conductors
with basic insulation.
