Operating Instructions RDF310.2/MM
RDF310.2/MM – thethermostat that allows you toset the ideal room temperature you want. The thermostat provides both
comfort mode and protection mode.
The fan operates either in automatic mode or at the selected speed when using manual mode. You can either rely on the
factory settings or make adjustments that suit your individual needs.
Are your rooms too warm or too cold?
+/ -Only applicable in Comfort mode.
Pressing the +or –button to increase or decrease the current room temperature setpoint for
Comfort mode in increments of 1.0 °C. The setting range is from 5...40 °C, unless it is limited
by parameters P05 and P06.
Do you want to set your controller to protection mode?
Press the button and the symbol shows, indicating that protection mode is selected.
In protection mode , the controller maintains the lower setpoint of heating for frost
protection via parameter P03 or the higher setpoint of cooling for moldy resistance according
to parameter P04.
Important:
If the setpoint of protection is set to OFF, the thermostat will not be activated in protection
mode.
Risk of frost!
Do you want to change the fan mode?
AUTO
Press the button until you have selected the desired fan mode.
In automatic mode, the fan speed is automatically selected by the controller and depends on
the setpoint and the actual room temperature. When the room temperature has reached the
setpoint, the fan either remains in fan speed low (factory setting) or switches off (parameter
P21).
In manual mode the fan operates independently and always runs at the same speed:
Low, medium or high.
The actual fan speed is indicated bythe number of fan symbols.
Low fan speed
Medium fan speed
High fan speed
Do you want to change from heating to cooling mode?
/
When pressing the button, the controller changes from heating to cooling or vice versa.
If the controller is commissioned cooling only or heating only, no changeover is possible
(please see parameter P22: factory setting manual H/C changeover)
Do you want to calibrate the displayed room temperature?
If the displayed room temperature does not match the actual temperature, the temperature sensor can be
calibrated by modifying parameter P07.
Proceed as described under “Changing the control parameters” and follow steps 1 through 3
to select parameter P07.
In step 4, modify the displayed room temperature to match the actual temperature.
Each pressing of the +or -button changes the temperature in increments of 0.5 °C and up to
a range of ±3 °C.
In step 7, the calibration is automatically stored 10 seconds after the last readjustment.

Changing the control parameters
To optimize the control performance, you can use local HMI to adjust a number of control parameters. Proceed as follows to change the
control parameters (see the table of “Commissioning by qualified HVAC staff” for factory settings):

1. Set the thermostat to protection mode .
2. Press and hold down the +and –buttons simultaneously for 3 seconds. Release them and,
within 2 seconds, press and hold down the +button for 3 seconds. The display shows P03.
3. Select the required parameter by pressing the +or –button as follows:
4. Press the +and –buttons simultaneously. The current value of the selected parameter displays on the screen.
Press the +or -.button to change the value.
5. You can either press the +and -buttons simultaneously to confirm the change, or wait
for 5 seconds to have the change saved automatically.
6. Repeat step 3 through 5 to change more parameters.
7. 10 seconds after the last display, all changes are saved and it returns to protection mode.
8. Press the button to switch to Comfort mode .
