Setpoint
The setpoint menu is normally accessed from the base display by a clicking on
the encoder knob.
If you wish to change the displayed value, click on the knob again and the
change indicators will start to flash to show that you are now in change mode.
Turn the knob, clockwise to increase the value, anti-clockwise to decrease.
When the desired value is shown, click on the knob to acknowledge. To return to
the base display, turn the knob.
For configurations involving a single output signal the setpoint is the starting point
for the output signal.
For configurations involving two diverging output signals with neutral zone
(heating
– cooling) the setpoint is placed in the middle of the neutral zone.
For configurations involving two outputs without neutral zone (heating
– heating,
cooling
– cooling, heating – damper or cooling – damper) the setpoint value is
the starting point for the first sequence (AO2).
External setpoint (SPI)
When using an external setpoint device, the setpoint can be read by clicking on
the knob while in the base display. If you click on the knob again, a symbol will
start to blink, indicating that an external setpoint device is being used and that
the setpoint cannot be changed via the display. External setpoint can be used for
control modes 1-4. The SPI input can also be read via the I/O menu.
Control mode 4, Radiator circuit control
If no room sensor is configured the setpoint menu is used to add a parallel
displacement to the outdoor curve. The displacement can be either positive or
negative. The setpoint is shown as
ΔSP.
If room sensor is activated the Setpoint menu is used to set the room
temperature instead of adding a parallel displacement.
An optional room sensor can be connected to UI1. If a room sensor is used, it
must be connected to the RDT410 before control mode 4 is selected. Otherwise,
the controller will not detect the sensor. To activate/deactivate the room sensor it
has to be connected/not connected to the Rdt410 before control mode 4 is
selected. The control program is automatically adapted when a room sensor is
connected. Deviation of the set room temperature is corrected by
increasing/decreasing the supply temperature by 3°C per one degree of
deviation. The setpoint is shown as SP.
To indicate that room control is activated the display symbol showing a
thermometer outside the house is replaced by a thermometer inside the house.
