the display shows the current value for that parameter.
Use keys '3' or '4' to modify the selected parameter
configuration; the value is quickly increased or decreased by
holding the keys '3' or '4' pressed.
P12: it extends drive output mode to the other channels; this
parameter make sense to be set on only if the thermostat is
paired with a multi-channel receiver (DLP ---).
COMPATIBILITY WITH NEW WAVE RADIO SYSTEM
The thermostat works with the New Wave radio receivers with
the following limits on the firmware versions (FW):
If this parameter is set on 'YES', all receiver channels will be
configured with ON/OFF or PWM setting of parameter P11 and
the related parameters from P13 to P17 hysteresis, proportional
band, additional time and cycle time. So, the thermostat can be
used to configure the output drive mode on the channel on
which self-learning was made and also on the other channels
available on the receiver. The receiver hysteresis can, for
example, be changed in this mode or make an output become
PWM, even if the channel will then be driven by a simple, not
configurable, thermostat.

P18: set-point temperature displayed by default. The
thermostat is set by factory default on “no” parameter, so the
thermostat shows the detected room temperature, but if this
parameter s set on “YES”, the displayed temperature is the set
point one, but the room temperature can be temporarily
displayed after the set-point temperature is modified. Instead, if
the parameter is set on “OnL”, “set-point only”, the thermostat
shows only the set-point temperatures (set-point comfort, set-
point economy) and it is not possible to display the room
temperature.

TEMPERATURE REGULATION
Type of action:

The thermostat can drive the output on the receiver, in ON/OFF
or PWM mode.
The valve drive in PWM mode allows proportional regulation
and, therefore, to regulate the room temperature with perfect
comfort and energy saving.
However, different rooms require different settings to obtain a
precise regulation.

The antifrost temperature can be set in the range 0.5 .. 25 °C or
disabled by setting the parameter until the value ‘no’ appears.
By factory default this parameter is set at 6 °C.

P04: room temperature offset.
The detected room temperature can be corrected by ±10.0 °C

- P15 Integration time
The proportional band in °C is the difference between set-point
and room temperature that guarantee the valve is fully open.
The narrower the proportional band is, the more reactive is the
system upon varying of the room temperature. An excessively
narrow proportional band setting can generate room
temperature oscillations or system instability. An excessively
large setting may fail to lead to the desired temperature set on
the set-point. No additional action is had when the integration
time is set at zero and the regulation is of P (Proportional) type.
If an integration time different from zero is set, the setting will
be P + I (Proportional + Integral). The shorter the integral time
is, the longer the integral action will be; vice-versa, a long
integral time generates a mild integral action. A mild or missing
integral action may prevent the set temperature on set-point to
be achieved in the room. An excessively strong integral action
may cause the room temperature to oscillate. These
parameters may require modifying, depending on the room
being worked on, in order to obtain the best regulation.
By default the device is set with 0.0 °C offset.

P05: sampling time.
To ensure batteries long life, the thermostat waits a period of
time between two transmissions that can be selected with a 3
or 10 minutes value. Thereforet, it’s normal that the
temperature displayed is not immediately updated; moreover
for the same reason it can be necessary to wait some minutes
until the output is turned on or off.
The 3 minutes option should be selected when the heating/
cooling system is fast, while with the common ‘slower’ heating
systems based on radiators or floor heating, even the 10
minutes option gives perfect accuracy and comfort.

P06 and P07: these two parameters set the temperature range
within which the set-point temperature can be chosen when the
thermostat is in heating mode. P06 is the lower limit and can be
freely set from 5.0 .. 35.0 °C, while P07 is the higher limit that
can be set in a range from the lower limit, chosen in P06, up to
35.0°C.

P08 and P09: these two parameters configure the temperature

previous two points.
The set-point temperature limits are re-defined upon changing
the cooling/heating settings. In the event the cooling/heating

will not be used and, instead, parameters P06 and P07 will

P10: NTC sensor configuration.
The thermostat is set by default prepared to operate with the
internal NTC (P10= Int). Alternatively to the internal sensor a
remote sensor can be wired to the connector 'REMOTE
SENSOR', shown with B in Fig. 6 and set parameter P10 as
'Ext': this way the internal sensor is disabled while the external
is enabled. Make sure to use the proper remote sensor type,
and respect the maximum wire length allowed.

P11: output PWM regulation, allows to choose whether the
receiver output must be driven in ON/OFF or PWM (Pulse
Width Modulation) mode.
Customisable hysteresis setting on parameter P13 will be with
ON/OFF regulation, while a proportional setting will be obtained
with PWM regulation (YES) that can be adapted to the different
room with proportional band, additional time and cycle time
parameters.
