Mini-Sewi KNX TH - KNX Sensor for Temperature and Humidity
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. In addition, an integrated actuating variable comparator can compare and output variables that were received via communication objects.
An integrated PI-controller controls a heating/cooling (according to temperature). Mini-Sewi KNX TH offers a second controller for ventilation (humidification/dehumidification according to humidity) and a warning can be output to the bus as soon as the comfort field, as per DIN 1946, is left.
Description
- Measuring the temperature, with mixed value calculation. The share of internal measurement value and external value can be set as a percentage
- Threshold values can be adjusted per parameter or via communication objects
- PI-controller for heating (one or two-stage) and cooling (one or twostage) according to temperature. Regulation according to separate setpoints or basic setpoint temperature
- 4 AND and 4 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
- 2 actuation variable comparators to output minimum, maximum or average values. 5 inputs each for values received via communication objects Configuration is made using the KNX software ETS
- Measuring the air humidity (relative, absolute), with mixed value calculation. The share of internal measurement value and external value can be set as a percentage
- Bus message, whether the values for temperature and air humidity are within the comfort field (DIN 1946)
- Dew point calculation
- PI controller for humidity according to humidity: Ventilate/Air (one-stage) or Ventilate (one or two-stage)
