Vari KNX T
Combined KNX Temperature Sensors
KNX temperature sensor. Optional with additional sensors for humidity, pressure. With temperature control, multifunctional modules and logic gates.
The sensors Vari KNX T for the KNX building bus system record the temperature. Further models measure additionally humidity and air pressure.
All measurement values can be used for the control of limit-dependent switching outputs. States can be linked via AND logic gates and OR logic gates. Multi-function modules change input data as required by means of calculations, querying a condition, or converting the data point type.
The sensors have integrated PI controller and a summer compensation for cooling.
The compact housing accommodates the sensors, evaluation circuits and bus-coupling electronics.
Models:
N° 70385 Vari KNX T, temperature sensor with summer compensation and temperature controller
N° 70386 Vari KNX TH, sensor for temperature and humidity with summer compensation, temperature and ventilation controller, dewpoint calculation
Sensors with brightness measurement: see Vari KNX 3L combined brightness sensors
- Temperature measurement with mixed value calculation. The share of internal measurement value and external value can be set as a percentage
- Switching outputs for all measured and computed values. Threshold values can be adjusted per parameter or via communication objects
- PI-controller for heating (one or two-stage) and cooling (one or two-stage) according to temperature. Regulation according to separate setpoints or basic setpoint temperature
- Summer compensation for cooling systems. A characteristic curve matches the target temperature in the room to the external temperature and sets the minimum and maximum target temperature values
- 8 AND and 8 OR logic gates, each with 4 inputs. All switching events as well as 16 logic inputs (in the form of communications objects) can be used as inputs for the logic gates. The output of each gate can be configured optionally as 1-bit or 2 x 8-bit
- 8 multi-function modules (computers) for changing the input data by calculations, by querying a condition or by converting the data point type
- Configuration is made using the KNX software ETS
Vari KNX TH additionally:
- Humidity measurement (relative, absolute) with mixed value calculation. The share of internal measurement value and external value can be set as a percentage.
In addition the bus output will indicate whether the values are inside the comfort field (DIN 1946). The dewpoint will be calculated. - PI controller for ventilation according to humidity: ventilate/air (one-stage) or ventilate (one or two-stage)
- 4 control variable comparators to output minimum, maximum or average values. 5 inputs each for values received via communication objects
Vari KNX TH-D additionally:
- Air pressure measurement: Output of the value as normal pressure and optionally as barometric pressure
