Intra-Sewi KNX T

The Sensors Intra-Sewi KNX T for the KNX building bus system measure the ambient temperature. Via the bus, the indoor sensors can receive external values of temperature and process them further with their own data to a total value (mixed value, e.g. room average). The 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).

Models:

N EL-70659 Intra-Sewi KNX T Built-in Type Sensor for Temperature (white)
N EL-70665 Intra-Sewi KNX T Built-in Type Sensor for Temperature (black)

Functions

• 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
