The basic level
The Base Display is shown when there is no operator activity.
I/O: By turning the knob counter clockwise when the Base Display is
shown, until the text I/O is displayed, and then clicking on the knob,
you can access a menu where you can look at the values and states
of all the inputs and outputs. To exit this menu, click on the knob and
then turn it clockwise and you will be returned to the Base Display.
Setpoint: When in the Base Display, a click on the encoder button
gives direct access to the Setpoint menu. To change the setpoint,
click on the encoder knob again. The "Menu holds changeable val-
ues" symbol will start flashing. Change the value by turning the knob
and confirm the change by clicking on the knob.
It is possible to either use an external Ni1000 setpoint device or to set
the setpoint value via the display. External setpoint can only be used
for control modes 1-4. For control mode 4, a room sensor is also re-
quired. For choice of internal or external setpoint, go to menu 1.E, set
EXT SP to ON for external setpoint or OFF for internal. When using
an external setpoint device, you can only see the current setpoint in
the setpoint menu.

Calculated setpoint: For control modes with outdoor temperature
compensation or cascade control, the controller does not work towards a
fixed setpoint value. Instead, it works towards a calculated setpoint, which
varies with the outdoor temperature or, when using cascade control, the
room temperature. The calculated setpoint is displayed
knob clockwise when in the Base Display.

Alarm handling: If there are any active alarms, clicking on the encoder
button will instead give access to the alarm handling menus. Here the
alarms are displayed and can be acknowledged. There is one menu dis-
play for each alarm with symbols showing which type of alarm it is.
If there are any active, unacknowledged alarms, the alarm indicator in the
Base Display will light up and start flashing. DO1 will be activated
sum alarm output if a 3-position actuator is not being used.
There are four different alarm types:
AL1 Frost protection alarm. The frost protection temperature has
fallen below 7°C. The frost protection temperatures are
fixed values. Frost protection control is initiated at 12°C.
AL2 High temperature limit switch activated.
AL3 Fan indication alarm. Either there is no fan indication input
on DI1 when the fan start output, DO3 is active or DI1 is
active although there is no fan start signal on DO3. The fan
alarm has a 30 second delay.
AL4 Sensor error. A sensor input is open circuit.
A symbol shows which type of alarm it is. Snowflake for frost protection,
sun for high temperature limit switch, a fan for fan indicator and the input
symbol for sensor error.
If there are multiple alarms, turn the knob to scroll through them. To ac-
knowledge an alarm, click the knob to enter change mode. Then turn it to
change No to Yes and click to acknowledge.
An alarm will remain on the alarm list until it is both acknowledged and

has reset. The alarm indicator in the Base Display will remain lit until
the alarm list is empty. However, it will only continue to flash as long
as there are unacknowledged alarms in the list. Thereafter it will
remain lit until all alarms have reset. If DO1 is used as alarm output it
will remain activated as long as there are unacknowledged alarms in
the alarm list.
DO1 cannot be used as an alarm output when 3-point control has
been selected.

RDT410 can be reset to factory settings by configuring Domestic hot
water control (mode 5) and setting the D-factor to 99. Go to the Base
Display. Then cut the power supply. When power is reapplied all con-
figuration and scheduler settings will be reset to factory setting.
