KNX TH-B-UP (discontinued item)

KNX Temperature/Humidity Sensor w. Display/Buttons

Replacement: KNX TH-UP Touch.

The Indoor sensor KNX TH-B-UP measures the temperature and air humidity and calculates the dew point. Via the bus, the sensor receives external measuring values and processes them to an overall temperature and air humidity value (composite results) together with its own data. The KNX TH-B-UP features two buttons that may be used to modify the room temperature (nominal temperature), to switch between the operating modes or as freely programmable bus buttons.

The KNX TH-B-UP provides six switched outputs with adjustable threshold values as well as additional AND and OR logic links. The sensor features a PI control for heating and cooling (depending on the temperature) as well as ventilation (depending on the air humidity) and can output a warning to the bus as soon as the comfort field (as per DIN 1946) is exited.

The integrated display shows own values as well as data received via the bus (e.g. date, time of day). The housing is supplemented with a frame of the switch series used in buildings, and thus fits seamlessly into the interior fittings.

KNX TH-B-UP, weiß (70370)
  • Measuring the temperature and air humidity (relative and absolute), calculation of the dew point
  • Composite values from own measured values and external values (proportions are adjusted as a percentage)
  • Display 1-3 lines (own values or values received via bus)
  • 2 buttons. Configuration as a bus button or to modify the nominal temperature and to switch between the operation modes
  • 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
