Linea XT platform control device, KNX standard, thermostat function for ambient

temperature control (heating and air-conditioning), 2- and 4-pipe system

management, 3-speed and proportional fan coil control, class I temperature

control device (contribution 1%) in ON/OFF mode, class IV (contribution 2%) in

PID mode, can be interfaced with actuator with proportional analogue outputs

to create a class V modulating room thermostat (contribution 3%), humidistat

function with ON/OFF control with respect to a set parameter, VOC (volatile

organic compound) function with ON/OFF control, proportional or to call up 2

scenarios, 2 push button function with configuration also as 1 rocker button with

status identification LED, central LED matrix to customise symbols or animation,

proximity function, white LED backlighting - 2 front modules

The device is KNX Data Secure and is equipped with a dedicated QR code to be used with ETS

(version 5.5 and later) during configuration.

The device is integrated with the following four sensors:

• Temperature sensor

The temperature sensor is integrated with the KNX home automation system and allows the

current temperature to be shown on the display or the data to be sent to the bus. It can be

used in the thermostat function to manage temperature control in 2 or 4 pipe systems (heating/

conditioning) and neutral zone (4 pipe systems only), with “boost” function to run a second

source to reach the desired thermal comfort quicker. The 4 available outputs (hot, cold, second

stage hot, second stage cold) for the fans can be configured to control 3-speed fan coils,

proportional fan coils or to control HVAC type split/VRV systems via third-party KNX interfaces

(if the first stage controls split/VRV systems, the second cannot do so). The thermostat is fitted

with a white LED matrix display and 2 keys to control the temperature setpoint and to turn the

temperature control system on/off. Opposite each key are white LEDs for the “up and down

arrow” or “+ and -” symbols. There are also two LEDs that indicate the heating valve control

phase (amber or configurable white LED) or cooling phase (blue or configurable white LED).

During the configuration phase, you can choose whether to view the room temperature, the

current setpoint or the current setpoint delta normally. The thermostat can control proportional

fan coils, 3-speed fan coils or HVAC type split/VRV systems via third-party KNX interfaces.

• Humidity sensor

The humidity sensor is integrated with the KNX home automation system and allows the

current humidity to be shown on the display or the data to be sent to the bus. It also allows the

humidistat function by sending an On/Off control on the bus when the humidity value increases

or decreases with respect to a parameter set during the configuration phase. It can be used

to manage ventilation and for dewpoint management, in combination with the temperature.

• VOC air quality control sensor

The VOC (volatile organic compounds) sensor is integrated with the KNX home automation

system and allows the air quality variations to be shown on the display or the data to be sent

to the bus. It also allows the sending of an On/Off control or to call up 2 scenarios when the

air quality worsens or improves with respect to parameters set during the configuration phase.

The VOC sensor, in combination with temperature and humidity, makes it possible to manage

ventilation to improve the quality of the air.

• Proximity sensor

The proximity sensor (the sensitivity of which can be set from ETS) enables the multisensor

activation by approaching a hand at a distance set during the configuration phase. Activation

propagates the information to the other controls on the same electrified XT mounting frame.

The time on standby is configurable. Proximity detection can be associated with the sending

of a bit control or the calling up of a scenario.

The device can be used in the following ways:

• Mode 1 - “Master thermostat”: Locally controlled thermostat for ON/OFF + setpoint

adjustment, possibly with interface block function (as per parameter) without symbols on the

keys. The symbols of the upper and lower keys can be customised, choosing from a list on

ETS.

It allows:

- Viewing of temperature and setpoint on central display. If the climate control art. 32144.x is

present, values T, H and VOC will be shown on the display every time the key is pressed.

- Editing of the values: summer_winter/fan speed/Celsius_Farenheit/on_off using the external

keys of the climate control.

• Mode 2 - “Slave thermostat”: It only works as a remote user interface for the master

thermostat and as a viewer for the internal sensors for internal temperature, humidity, and air

quality. The slave thermostat can modify the setpoint set on the master thermostat by sending

the new value to the bus. The average temperature calculated with related weighting and

distributed by the master thermostat can be displayed on both the master thermostat and the

slave thermostats. Temperature control is performed by the master thermostat based on the

average temperature. For this function to work, the slave thermostats must send their detected

temperature to the master thermostat, which then distributes the average temperature to be

displayed and the setpoint.

• Mode 3 - “Sensor viewer”: Viewer of the values T, Text, H and VOC on the display. It is used

as a simple viewer and normally shows the current temperature. Using the two keys on the

device (or with climate control art. 32144.x) the values of the local temperature, remote probe

temperature, humidity and air quality can be browsed and displayed.

• Mode 4 - “Rocker switch/push button control”: Control with 2 push buttons or 1 rocker

switch where the 2 keys can be configured as 2 push buttons or grouped together as 1 rocker

switch. The symbols of the upper and lower keys can be customised. In the case of 1 rocker

switch the central white LED matrix can be used for customised symbols or for animation, while

in the case of 2 push buttons it can be used to display any alarms, load status and scenario

activation with customised symbols. The values T, H and VOC are not shown on the display

but they are made available on the bus.

• Mode 5 - “Push button control/rocker switch with thermostat function”: Control with 2 push

buttons or 1 rocker switch where the 2 keys can be configured as 2 push buttons or grouped

together as 1 rocker switch + thermostat.

The symbols of the upper and lower keys can be customised. In the case of 1 rocker switch

the central white LED matrix can be used for customised symbols or for animation, while in the

case of 2 push buttons it can be used to display any alarms, load status and scenario activation

with customised symbols.

The values T, H and VOC are not shown on the display but they are made available on the bus.

•Mode 6 - “Room number”: Allows you to view the room number from 0 to 9999. The lower

push button can be programmed for “bell” function with message sending on the bus.

Functions available for each mode:

• Humidity/air quality/external temperature values made available on the bus.

• Sending of ON/OFF controls when the humidity value measured increases/decreases with

respect to a threshold configured on ETS (sending of two controls in reference to two

thresholds).

• Sending of ON/OFF control or activation of two scenarios when the air quality improves or

worsens with respect to a threshold configured on the ETS App.

• Wake-up of device upon external events (e.g. change in contact interface status, PIR sensors).

• Sending of ON/OFF control or activation of a scenario upon proximity detection

CHARACTERISTICS.

• Occupies 2 front module size 30.5 mm

• Brightness on standby levels selectable from the related parameters

• Hysteresis: adjustable from 0.1°C to 1°C.

- Temperature measurement precision of the built-in sensor: measurement range from 0 to 40°,

±0.5 °C between 15 °C and 30 °C, ±0.8 °C at the extremes.

• Precision of integrated sensor humidity measurement: ± 6RH% typical (in still air at 20 °C and

50RH%)

• Management of 2- and 4-pipe systems.

• Heating, air conditioning with management of the neutral zone.

• Operation via a dedicated ON/OFF or 6-way or proportional hot/cold valve actuator (0-10 V,

4-20 mA).

• Fan coil management (3-speed/proportional and split/VRV system control).

• Selectable PID or ON/OFF control algorithm:

- the ON/OFF algorithm is the control which, on exceeding the set temperature increased by

the threshold value (vice versa for air conditioning), the heating is switched off to then be

turned back on when the room temperature drops below the set temperature.

- PID is a sophisticated algorithm capable of keeping the temperature in the room more

stable and it works by switching the system on and off so as to be like a gradual increase

or decrease in the system’s thermal (or refrigerating) power; ideal for use in floor heating

systems, the algorithm needs to be properly calibrated according to the type of environment

and system.

• Boost function: control of an auxiliary actuator to speed up the heating or air conditioning of

the environment.

• Mild season function: available from the supervisor only for systems configured with 4 pipes;

when active, the secondary output is controlled with its own parameters.

• Possibility of using external sensors connected to the bus for:

- Replacement of the internal sensor.

- Average with the internal one.

- Screed temperature limitation.

- Display on display only.

• Open window management function with delayed power on management.

• Device can be interfaced natively with third-party systems (KNX systems).

• Remote manageable device.

• Anti-stratification function that compares temperatures detected at 2 different heights within the

room. If the temperature difference exceeds the value set in a parameter, it controls the fans to

run at minimum speed without activating the valve.

• Possibility of using an offset to correct the reading of the temperature measured according to

a possible sample thermometer in order to compensate for errors due to special installations

(North-facing wall, proximity to hot/cold water pipes, etc.).

• The thermostat can be controlled from a key on the device 32144.x for the ON/OFF, scrolling

the viewable values, heating/cooling, fan speed modification, degrees Celsius/Fahrenheit

modification, display functions.

• Humidity check: control of an actuator to activate humidification or dehumidification systems.

• Air quality check: control of an actuator to activate air recirculation systems. Calling up of

scenarios if the air quality improves or worsens.

• Dewpoint calculation: if there is a risk of dew forming, the thermostat is switched off and sends

an alarm signal on the bus to the dedicated object (the delivery temperature required for the

calculation can be received via bus or be set fixed using a parameter).
