Menu
OK
Choose control mode in menu level 0 by clicking on the knob so the
"Menu holds changeable values" symbol (see the section Display
symbols below) starts flashing, and then turning the knob. When the
control mode you want to choose is displayed, click once more on the
knob so the "Menu holds changeable values" symbol stops flashing.
When you have chosen the control mode, you move between the
menu levels by turning the knob when the "Menu holds changeable
values" symbol is not flashing.
In some cases, making a certain choice in one menu will mean that
you will only see certain other menus.
Example: To set the I-time for control mode 3 (Cascade connected
room / extract air temperature control), go to menu 3.5. Click on the
encoder knob. The "Menu holds changeable values" symbol will start
flashing. Change the value by turning the knob and confirm the change by
clicking on the knob.
To exit the 10-second level, go to Menu OK and click on the encoder
knob. The Time and Scheduler level will be displayed. To exit the Time
and Scheduler level, go to the OK menu after the scheduler menus, and
click on the encoder knob. You will be returned to the Base Display.
There is also a time-out function that will automatically exit the configura-

All configuration settings become valid as soon as they are entered by
clicking the encoder knob. They are however not written to the flash
memory until you exit the configuration level either via the OK menu or via
the time-out function.

be kept as they were before you entered the configuration level.

See the "RDT410 Manual" for more information about the
configuration menus in the 10-second level. The manual can be
downloaded from www.sauter-controls.com.
The clock and scheduler level (3-second level)
This level is reached from the Base Display by holding the encoder button
depressed for 3 seconds. The 3-second level holds all menus for setting
the clock and scheduler program. The scheduler function is only avail-
able for control modes 1, 2, 3 and 4. Note: The controller must display
the Base Display when pressing the encoder knob to reach the 3-second
level.
This sample display shows that the time is 13:48 on a Friday, the fifth
day of the week. To set the clock, click the knob and the day-of-the-

week number will start flashing. Turn the knob until the correct day
is shown, Monday is 1, Tuesday 2 etc, and then click the knob again
to acknowledge the choice. Now the hours will flash. Set them in the
same way and then finally the minutes. After confirming the minutes
the menu will change to show the first of the scheduler menus. Note:
The clock is not year- or date-based and does not have automatic
summertime adaption.
There are 4 ON-points and 4 OFF-points. Each point has its own
menupage where 0.1, 0.3, 0.5 and 0.7 are ON-points and 0.2, 0.4, 0.6
and 0.8 are OFF-points.
Control modes 1, 2 and 3
For control modes 1-3, the ON-points will start the unit and the OFF-
points will shut it down.
Example: You wish the unit to run Monday to Friday between 07:30
and 18:00, Saturday 8:00 to 14:00. Set the first on-time to day 8
(which corresponds to every day Monday through Friday) and 7:30,
the first off-time to day 8 and 18:00. Set the second on-time to day 6
(the sixth day of the week) and 8:00 and the second off-time to day 6
and 14:00. Set all other menus to day -- (unused menus).
After the eight switching point menus there is a ninth, 0.9. There the
present output status of the scheduler is shown and you can manu-
ally override the setting. If, for example, the switch is shown as ON
and you change it to OFF it will remain off either until you manually
change it to On again or until the next timer ON-point is reached.
After the scheduler menus there is a final menu, OK. A click on the
encoder knob will exit the Time and Scheduler level and return you to
the Base Display.
Control mode 4
Control mode 4 uses the scheduler for switching to economy mode
(ECO) where the temperature is lowered by a settable number of
degrees. The ON-points will switch ECOnomy period on and the OFF-
points will switch back to comfort temperature.
Example: Every weekday morning you want the temperature to start
rising at 06:00 and remain at comfort level until 21:00. On Saturday
and Sunday you want high temperature from 07:00 to 23:30.
Set first on-time to day 8 and 21:00, the first off-time to day 8 and
06:00. Set the second on-time to day 6 and 23:30 and the second off-
time to day 6 and 07:00. Set the third on-time to day 7 and 23:30 and
the third off-time to day 7 and 07:00.
After the eight switching point menus there is a ninth, 0.9. In this
menu you set the number of degrees you wish to lower the room tem-
perature setpoint during the economy periods. If no room sensor is
connected the supply water setpoint will be lowered by 3 times the set
value.
After the scheduler menus there is a final menu, OK. A click on the
encoder knob will exit the Clock and Scheduler level and return you to
