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.
