Nighttime temperature
The nighttime temperature is adjusted
with the lower adjustment button [2].
The nighttime temperature
is independent of the daytime
temperature. The nighttime temperature
is adjusted between -5°C and
+25°C with the adjustment button
[2]. The absolute value is displayed
in the right-hand half of the display.
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.
Off
The controller is switched
off by simultaneously pressing the ¹
and 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.
Depending on the selected units,
"Heating or Ventilation", and additional
relay out is activated for signalisation.
Display with switched "Heat" output
Display with switched "Ventilate" output
The "Heat/Ventilate" functions are
switched only with the specified key
combination.
In "Heat" mode, the activated relay
is displayed on the left-hand side
of the display with an upwards pointing
arrow, in "Ventilate" mode, with
a downwards pointing arrow.

CAUTION
There is no frost protection
for excessively low overnight
temperatures.
Daytime temperature (daytime operation)
The desired temperature (+5 to +40°C)
is adjusted with the upper adjustment
button [1]. 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.

Hand key
The key is used to modify the current
temperature level in hourly 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.
Reset key
Three different reset options are
available:
1. Start-up reset:
The R [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 R[4] must
be pressed.
After releasing the Rkey, the –and
PROG keys must continue to be pressed
until the version number (Id:02...)
appears on the display.
3. Malfunction RESET (acknowledgement)
In the event of a malfunction (open
contact at external input), the –and
PROG (RESET) key combination
can be used to force a malfunction
acknowledgement of the relay.
The relay is activated for as long
as the key combination is pressed.
Any previously entered individual
time program and parameter
settings will be lost.
NOTE
Malfunction code
In the event of a (heating unit)
malfunction (contact opened)
at an external input, "StoErng"
is displayed on the control unit.
In this status, the controller cannot
be operated, however the control unit
continues to function normally.
The special "RESET" key combination with
the –and PROG keys allows a malfunction
to be acknowledged and reset. If this
key combination is pressed for longer
than 5 seconds, the "flashing code"
from the heating unit on the display can
be read off. Each flashing pulse from
the heating unit results in the malfunction
text being hidden for a brief moment.
In the event that multiple units are
involved in a malfunction shutdown,
it is likely that the flashing codes of
the individual units will overlap. In this
case, each unit must be checked separately
for the respective malfunction.
If multiple units are connected to
the ATR-10 and multiple units have
a malfunction, it is highly likely
that the flashing codes will overlap.

The +and –keys can be used to modify
the respective flashing value (P01 - P16).
The SET key takes you to the next
setting (Program point number -> Time
-> Days of week -> Temperature level).
Pressing the SET key takes you
to the time setting.
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.

16 program spaces are available.
These allow up to 112 switching times
to be programmed.
The program point number
P01-P16 appears on the display,
the corresponding time and day of
the week at/on which the corresponding
temperature level becomes effective.
The temperature level that is active
on the various day is displayed
on the right with the indicators.
Pressing the +and –keys modifies
the switching time point of the clock
in 10 minute increments.
The clock changes automatically
between summer/winter time.
