Electronic thermostat for ambient air temperature control (heating and air conditioning) of 2 independent zones, KNX standard, 1 NO relay output 4
A 24 V~, 1 input for temperature sensor 20432-19432-14432, 1 programmable digital input - 2 modules.
The thermostat is suited for ambient temperature control (heating and air-conditioning) and it
can interact with other thermostats (whose measured temperatures can be used to determine
the "weighted" temperature) and with a supervision centre (PC in reception or technical room
where, for example, the Well-contact Suite software is installed). The device is able to manage
2 temperature zones completely independently; in practice it is as if it were composed of two
independent thermostats monitoring one zone each (thermostats A and B). The thermostat A
and the thermostat B will manage the corresponding heating/air-conditioning systems based on
the average of the temperature values measured by the temperature sensors that can be asso-
ciated with A and B. The thermostat is provided with an NC or NO programmable relay that can
be used for generic use (switching on light/closing zone solenoid valve/activating electric towel
heater, etc.) or to control speed 1 of the fan-coil managed by the thermostat A (or alternatively by
the thermostat B). In addition, it has an NC or NO programmable digital input that can be used
for applications such as, for example, detecting an open window or for other general uses for
one or for both thermostats A/B. The device is equipped with a display and four front buttons to
control the temperature set-point and the speed of the fan-coil.
CHARACTERISTICS.
• Supply voltage: BUS 29 V SELV.
• Consumption: 10 mA
• Terminals:
- TP bus;
- digital input for NO or NC contact (with no potential, SELV);
- NO relay output (
24 V~ SELV 4 A cos
• Operating temperature: -5 °C - +45 °C (inside)
• ErP classification (Reg. EU 811/2013): class I, contribution 1%;
±0.5 °C between 15 °C and 30 °C
• Reading accuracy:
±0.8 °C at the extremes
• This device contains only SELV circuits that must be kept separate from circuits with dangerous
voltage.
• Temperature sensors that can be managed via the thermostat 20430-19430-16915-14430.
- Internal NTC
- Possibility of connecting an external NTC art. 20432-19432-14432
- Possibility of using the temperature values sent over the bus from 8 different KNX temperature
sensors (DPT_Value_Temp data).
- Maximum length of the connecting cable of the external NTC: 60 m. Use a twisted cable with
a minimum cross-section of 0.5 mm
(art. 01840)

• Reference temperature
For each of the two thermostats A and B the reference temperature for the climate control is
the weighted average among all the available temperature sources (if present):
- Internal NTC
- External NTC art. 20432-19432-14432
- via bus (KNX sensors 1-8 temperature)
OPERATION.
The configuration of the thermostat, physical address, parameters, its operation, etc., is done
with the ETS software.
If the thermostat is loaded with an incorrect ETS application, the red LED on the back of the
device will flash and all the LCD segments will blink on the display ("device type" error).
To restore the desired configuration, load the device with the correct ETS application.
The user, by means of the front buttons, will be able to change the temperature set point and the
speed of the fan-coil; changing these parameters forces the thermostat onto manual operation.
USING THE THERMOSTAT.
Using the thermostat it is possible to set:
• the temperature set-point in the room (the change can only be made within certain limits set
by the control centre or reception, etc.);
• the speed of the fan-coil.
To change the temperature press the + or - button twice:
• on pressing it the first time the display will show the currently set temperature;
• on pressing it the second time the increase/decrease in the displayed value will begin.
The selection of the thermostat B is made with the button F.
IMPORTANT: Max length of the cable for the connection of the inputs = 30 m.
Note: In the phase of installation provide for cable connection lengths that allow extracting the
device from the flush mounting box so as to be able to access the configuration button.
INSTALLATION RULES.
Installation must be carried out by qualified persons in compliance with the current regulations
regarding the installation of electrical equipment in the country where the products are installed.
CONFORMITY.
EMC directive. Standards EN 50090-2-2, EN 50428.
REACH (EU) Regulation no. 1907/2006 – Art.33. The product may contain traces of lead.
WEEE - Information for users
If the crossed-out bin symbol appears on the equipment or packaging, this means the product must not be
included with other general waste at the end of its working life. The user must take the worn product to a sorted
waste center, or return it to the retailer when purchasing a new one. Products for disposal can be consigned free
of charge (without any new purchase obligation) to retailers with a sales area of at least 400 m
less than 25 cm. An efficient sorted waste collection for the environmentally friendly disposal of the used device,
or its subsequent recycling, helps avoid the potential negative effects on the environment and people's health,
and encourages the re-use and/or recycling of the construction materials.
