C13: Determines which fan speeds can be set
with the “fan“ button.
In certain installations it may be necessary to limit “
“ button
function.
Table 3 shows the available combinations.
C14, C15 and C16: These parameters allows to set which function
must be associated to the 3, 4 and 16 inputs.
Table 4 shows which functions can be associated to each input. It
is the installer’s responsibility that each function is not associated
to more than one input.
See the “External inputs - terminals 3, 4 and 16” section for further
information.
C17: Determines which operating modes can be set with the
button “
“. In certain installations it may be necessary to limit
button “
“ function.
Table 5 shows the available combinations.
C18: This parameter confi gures the integration “∆ set point“ of the
electric heater system.
See the “Integrating electric heater system” section for further
information.
C19: If the buttons are inactive for a few seconds the thermostat
returns to display the room temperature.
When this parameter is set to 1, the thermostat displays the set-
point temperature instead of room temperature.
ROOM TEMPERATURE CORRECT ACQUISITION
For a correct temperature acquisition it is mandatory to
remember and apply the following tips:
- In order to have an accurate room temperature acquisition the
controller must be installed far from heat sources, airstreams or
cold walls (thermal bridges). When the remote sensor is used
in conjunction with the controller, then this note is to be applied
to the remote sensor itself.
- When a remote sensor is used, do not use the same duct
for signal wires and power (mains) wires, as the temperature
reading accuracy could be impaired. Wirings can be usefully
made with bipolar screened cable, whose screen is only wired
at the regulator side (terminal 14) with 1,5 mm² minimum
cross section and 15 m. maximum length.
- In the normal operation with internal sensor, the controller
conditions the signal acquired according an exclusive
algorithm designed to compensate the heat generated from its
internal components. From this derives that the temperature
value displayed at turn-on can be actually lower than the real
one. This must be considered a normal behaviour: anyway in
some minutes this difference should decrease down to zero.
- In case the controller should drive with its outputs large
loads (whose current is close to the maximum rated value) it
might happen that the internal components heat gets bigger.
This temperature increase could in turn infl uence the room
temperature acquisition when the internal sensor is used. This
problem is not present when the remote temperature sensor
is used.
- When, for any reason, the room temperature accuracy is
considered unsatisfactory (due to the above mentioned
reasons), it can be corrected with parameter P11.
- When the controller is powered with 230V~ it is mandatory to
respect the live and neutral (L and N) position during wiring.
