Configuration end is indicated with the wording 'End'. Press
' ' again to save configuration and the thermostat switches
to normal operation.
At any time, by pressing for a few seconds the ' ' key, the
configuration menu is quit without saving any changes made.
When scrolling through the parameters list, with keys '' or '',
the display shows the current value for that parameter.
Use keys '' or '' to modify the selected parameter's
configuration; the value is quickly increased or decreased by
holding the keys'' or '' pressed.
The ' TEST ' procedure is automatically activated after
configuration end and saving. During this test, the thermostat
communicates information on the output configuration to the
receiver, which the latter saves in a versatile manner and is
used to adjust the temperature in the wanted mode.
It is important, therefore, to run self-learning on the receiver
before modifying configuration; and it is important to check the
receiver correctly receives the ' TEST ' controls at the end of
configuration.
Reset installer configuration
To reset installer configuration in order to bring all parameters
to factory default values, access the configuration and, when
the display shows 'Con', simultaneously press '' or '' for a
few seconds until the screen goes back to normal mode.
Description of configuration parameters
The installer configuration parameters are shown in table 1
and explained below.
Some installer parameters may not be displayed as only
current configuration required parameters are proposed
(the way of configuring a parameter, may exclude one or
more subsequent parameters).
P01: allows using the thermostat (trA) or receiver (rEC)
heating/cooling mode.
This parameter must only be modified to ' rEC ' (receiver)
when wanting to use the thermostat in association with a
programmable thermostat in a New Wave radio system or the
external heating/cooling selection input or economy input of
the New Wave relay modules.
P02: allows to customise the regulation modes that can be
selected with the key ' '. The regulation modes available
are Comfort, Economy and OFF: each of these can be enabled
or disabled by changing P02.
Economy mode will be replaced by Auto mode if P01 is set as
'rEC'.
The OFF mode will be replaced by Antifrost mode in case P03
is configured with an antifrost temperature.
P03: with this parameter the Antifrost temperature can be set:
this will be maintained when the thermostat is turned off.
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 default this parameter is factory set at 6 °C.
P04: room temperature offset.
The detected room temperature can be correct by ±10.0 °C
with the offset, in order to correct any systematic reading
errors due to thermostat positioning in unsuitable areas for
detecting the room temperature.
By default the device is set with 0.0 °C offset.
P05: sampling time.
To censure a long life of the batteries, the thermostat waits a
period of time between two transmissions that can be selected
as 3 or 10 minutes.
It is therefore 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, meanwhile with the common ‘slower’
heating systems based on radiators or floor heating, even the
10 minutes option gives perfect accuracy and comfort.
In any case, at any time, pressing the ' ' key forces an
update of the system.
Choosing the longest interval delivers the longest battery life.
P06 and P07: these two parameters configure the temperature
range within which the set-point temperature can be set when
the thermostat is in heating mode. P06 is the lower limit and
can be freely configured from 5.0 .. 35.0 °C, while P07 is the
higher limit that can be configured in a range from the lower
limit, chosen in P06, up to 35.0°C.
Therefore, the maximum range is 5 .. 35 °C and can be easily
reduced based on installation requirements.
P08 and P09: these two parameters configure the temperature
range within which the set-point temperature can be set when
the thermostat is in cooling mode, with the same logic of
previous two points.
The set-point temperature limits are re-defined upon changing
of the cooling/heating setting. In the event the cooling/heating
selection is on the receiver (P01=rEC), these two parameters
will not be used and the settings of parameters P06 and P07
are always used.
P10: NTC sensor configuration.
The thermostat is factory set for the operation 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. 5 and set parameter P10 as 'Ext': in this way the internal
sensor is disabled while the external is enabled. Ensure to use
the proper type for remote sensor, and respect the maximum
wire length allowed.
P11: output PWM adjustment, allows choosing whether the
receiver output must be driven in ON/OFF or PWM (Pulse

Width Modulation) mode.
Customisable hysteresis adjustment on parameter P13 will be
had with ON/OFF adjustment, while a proportional adjustment
will be had with PWM adjustment (YES) that can be adapted
to the different room with proportional band, additional time
and cycle time parameters.
P12: extends drive mode of output to other channels; this
parameter is only significant if the thermostat is coupled with a
more channel receiver (DLP ---).
If this parameter is set on 'YES', all receiver channels will be
configured with ON/OFF or PWM setting chosen in parameter
P11 and relative parameters from P13 to P17 hysteresis,
proportional band, additional time and cycle time. The
thermostat can, in this way, be used to configure the output
drive mode on the channel on which self-learning was made
and on the other channels available on the receiver also. 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.
P13: hysteresis, it represents the hysteresis width used when
an ON/OFF adjustment (no) is chosen in P11.
P14: PWM proportional band, it is used for proportional
adjustment when the output is configured in P11, for being
driven with PWM (YES).
P15: integrative time in minutes, it is used for proportional
adjustment when the output is configured in P11, for being
driven with PWM. The integrative action is not had if set zero.
P16: PWM cycle time, it is the duration of each PWM cycle in
minutes, meaning every how many minutes is the variable
width impulse repeated.
P17: minimum time of PWM ON, meaning the minimum PWM
impulse width or the minimum output switch-on time. This
parameter must be set with the actuator's opening time, in the
event an electro-thermal actuator is connected, otherwise
switch-ons for lower times respect to opening time, do not
generate significant output actions.
P18: this parameter allows you to choose whether to activate
the default display of the set-point temperature set by the user
instead of the normal display of the room temperature. If the
option is left to ‘no’, the display default shows the room
temperature, whereas if the parameter is modified to ‘YES’ the
set-point temperature will be default displayed.
TEMPERATURE REGULATION
The thermostat can drive the output on receiver, in ON/OFF or
PWM mode.
The valve's drive in PWM mode allows proportional regulation
and, therefore, to regulate the room temperature with
maximum comfort and power saving.
However, different rooms require different settings to obtain
precise adjustment.
The parameters responsible for adjustment quality are:
- P14 Proportional band
- P15 Integration time
The proportional band in °C is the difference between set-point
and room temperature that ensures the valve is fully opened.
The narrower the proportional band, 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 lead to not reaching the set temperature on
set-point, in the room. No additional action is had when the
integration time is set at zero and the adjustment is of P
(Proportional) type.
Adjustment will be of P + I (Proportional + Integral) tpe by
setting an integration time different from zero. The shorter the
integral time the longer is the integral action, 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 from being reached 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 adjustment.
DISPLAY BACK-LIGHTING
Switch-on of the display Switch-off is automatic after 20
seconds from last button pressure.
BATTERIES INSERTION/REPLACEMENT
The display permanently shows the batteries charge state by
means of symbol ' '. Batteries are charged to maximum if
all three level indicators inside the symbol are on.
On the contrary, the batteries are drained and must be
replaced when the symbol appears completely empty ' '.
The symbol ' ' flashes when the batteries are excessively
drained to allow radio transmission.
For batteries replacement proceed as explained in points 1, 2
and 4 at page 3.
