After applying power, the controller makes a reset during which all LCD segments flash,
indicating that the reset has been correctly made. This takes about 3 seconds. Then,
the controller is ready for commissioning by qualified HVAC staff. The control
parameters of the controller can be set to ensure optimum performance of the whole
system (also refer to "Setting the control parameters").
• Only with RDF110: Depending on the application, the heating / cooling mode needs
to be set via parameter P22. Factory setting is "Cooling only". When using the
"Automatic heating / cooling changeover" function, P22 must be set to "Automatic
H/C changeover".
Note: When P22 is set to "Automatic H/C changeover", the built-in sensor is used
for acquiring the room temperature
• If the controller is used in conjunction with a compressor, the minimum output on
time (parameter P15) and off time (parameter P16) of Y11 must be adjusted in order
not to harm the life time of the compressor
• If the room temperature displayed by the controller does not accord with the room
temperature effectively measured, the temperature sensor can be recalibrated. In
that case, parameter P07 must be changed
• For comfort and energy saving reasons, it is suggested to review the setpoints and
setpoint ranges (parameters P01...P06) and, if necessary, to change them
accordingly
• Only with RDF110: Parameters P98 and P99 are diagnostic values and help check
the system. With P98, the status of the active temperature sensor is shown and,
with P99, the status of the heating / cooling changeover sensor
The devices are considered electronics devices for disposal in term 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.
