Touch Screen Flush-mount Room Thermostats with KNX Communications
2014-09-10
The thermostat's control parameters can be set to ensure optimum performance of
the entire system (refer to basic documentation P3174).
The parameters can be adjusted using
−
Local HMI
−
Synco ACS
−
ETS4
For commissioning via local HMI, refer to user manual B3174... for setting the
passwords.
•
The control sequence may need to be set via parameter P01 depending on the
application. The factory setting for the 2-pipe application is "Cooling only"; and
"Heating and Cooling" for the 4-pipe application.
•
When the thermostat is used with a compressor, adjust the minimum output on-
time (parameter P48) and off-time (parameter P49) for Y1 / Y2 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.
Touch and hold
for more than 5 seconds to activate programming mode, which
is indicated on the display with
Pr09
. Programming mode remains active until
thermostat identification is complete.
Assign device address (P81) via HMI, ACS or ETS4.
With device address set to 255, the communication is deactivated (no exchange of
process data).
Use ETS4 to assign the KNX group addresses of the RDF communication objects.
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.
Disposal
The devices are considered electronics devices for disposal in terms of European
Directive 2012/19/EU and may not be disposed of as domestic waste.
•
Dispose of the device via the channels provided for this purpose.
•
Comply with all local and currently applicable laws and regulations.
