KNX is the world’s only open standard for home and building control that has been adopted, at last count, by 405 Manufacturers from 41 different Countries. Together these manufacturers provide customers with a vast range of choice for KNX-certified products. These devices and components enable a single system solution (combining lighting, heating, blinds / shutters, security systems, ventilation and air-conditioning systems, signalling and monitoring systems, remote control, metering, audio / video control etc) on one platform.

What Are The Key Advantages of KNX?

KNX is the Worldwide STANDARD for Home and Building Control.

What Are The Key Advantages of KNX?

KNX Product Certification guarantees Interoperability & Interworking of products.

What Are The Key Advantages of KNX?

KNX is Independent from any hardware or software technology.

Why choose KNX for your business?

The Smart home market will continue to be one the fastest growth areas in the building trade. It is expected to be just under 1 Billion dollars (£800 million) in the UK this year alone and is expected to grow at just under 30% annually to 2021, reaching a household penetration of 40%.The KNX Association saw a 30% increase in Certified KNX installers (Partners) across 160 Countries. A total of 7,344 – of which the UK was 11th/12th.

KNX touch-thermostat 2M black

CHARACTERISTICS

Supply voltage: BUS 29 V SELV.
Consumption: 10 mA.
Terminals:
- TP bus;
- Digital input for NO or NC contact (with no potential, SELV);
- Maximum distance between the input contact and the thermostat: 30 m;
- NO relay output ( 24 V~ SELV 4 A cos 1; 24 V~ SELV 2 A cos 0.6).
Operating temperature: 0 °C - +40 °C (inside).
ErP classification (Reg. EU 811/2013):
- ON/OFF: class I, contribution 1%;
- PI: class IV, contribution 2%;
- with actuator with proportional analogue outputs KNX: class V, contribution 3%
This device contains only SELV circuits that must be kept separate from circuits with dangerous voltage.
RGB backlit touch display with colours that can be configured via ETS parameter:
- fixed colour chosen by the installer;
- dynamic colour change depending on the set-point value by enabling the Ecometer function
Internal temperature probe: measurement range from 0 to 40 °C with reading accuracy of: ≤±0.5 °C between 15 °C and 30 °C; ≤±0.8 °C at the extremes.
External temperature probe: measurement range from -20 to 70 °C with comparable accuracy to the internal temperature probe; beyond the stated temperatures, the error increases.
Temperature sensors that can be managed by the thermostat 02952
- Internal NTC.
- Possibility of connecting an external NTC art. 02965.1-20432-19432-14432.
- Possibility of using the temperature values sent over the bus from 8 different KNX temperature sensors ( DPT_Value_Temp data)
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. 02965.1-20432-19432-14432;
- via bus (KNX temperature sensors 1 to 8).
The weights of the various temperature sources are set via ETS; source temperatures with weight 0 are not included in the calculation of the reference temperature.
Systems management with:
- 2/4 pipes and on/off and proportional valves;
- Fan coils with 3 speeds, 3 proportional and constant proportional speeds;
- Neutral zone (only 4 pipes).
- Control algorithm: On/Off, I, PI.
Boost function: each thermostat A and B has a second temperature control stage which, if enabled, triggers to support the first one when the detected temperature differs from the desired set-point by at least a predetermined threshold”.
Ambient humidity display: the thermostat can display ambient humidity whose value is sent by the bus to the thermostat via appropriate data points.
Dew point
System protection functions:
- Antifreeze and Too Hot;
- Floor temperature protection;
- Generic alarm.
16 scenarios.
