The thermostat's control parameters can be set to ensure optimum performance of
the entire system.
The parameters can be adjusted using
– Local HMI
– Synco ACS
– ETS
Commissioning of switching groups for RDF301.50 is only possible with ETS).
The control parameters of the thermostat can be set to ensure optimum
performance of the entire system (see section 3.13, control parameters).
The control sequence may need to be set via parameter P01 depending on the
application. The factory setting is as follows:
Application Factory setting P01
2-pipe and chilled / heated ceiling 1 = cooling only
4-pipe, chilled ceiling and radiator 4 = heating and cooling
When the thermostat is used with a compressor, adjust the minimum output on-
time (parameter P48) and OFF-time (parameter P49) for Y11/Y21 to avoid
damaging the compressor or shortening its life due to frequent switching
Recalibrate the temperature sensor if the room temperature displayed on the
thermostat does not match the room temperature measured (after min. 1 hour of
operation). To do this, change parameter P05
We recommend to review the setpoints and setpoint ranges (parameters
P08…P12) and change them as needed to achieve maximum comfort and save
energy
The programming mode helps identify the thermostat in the KNX network during
commissioning.
Press buttons “operating mode”
and “+” simultaneously for 6 sec to activate
programming mode, which is indicated on the display with "PrO
g
".
Programming mode remains active until thermostat identification is complete.
Use ETS to assign the KNX group addresses of the thermostat's communication
objects.
RDF301.50 has 2 switching groups with a pair of buttons each, which must be
configured via ETS. The switching groups only work in S-mode.
Each device has a unique KNX serial number inside the front panel. An additional
sticker with the same KNX serial number is enclosed in the packaging box. This
sticker is intended for installers for documentation purposes.
