The tasks of the RDE100.DHW Siemens controllers include:

  • Room temperature control with built-in sensor
  • Selecting the operating mode using the touch buttons
  • Time program configuration (individual days, 7 days or "5-2" days)
  • Display of the current room temperature or setpoint (° C or ° F)
  • Keyboard lock (manual)
  • Settings lock
  • Periodic pump run
  • Reset of configuration parameters to factory settings
  • Independent DHW heating function with its own time program

The RDE100.DHW controller works with the following devices from the SIEMENS offer:

  • Electrothermal actuator (for radiator valves) STA23
  • Electrothermal actuator (for valves with 2.5 mm stroke) STP23
  • GDB damper actuator
  • GSD throttle actuator
  • GQD damper actuator
  • Rotary damper actuator GXD

One step to convenient management of your heating system

The RDE100.1DHW Siemens room temperature controller has a clear administrator panel. Information about current parameters is shown on a clear display. The user has a choice of 4 operating modes: automatic, comfort, energy-saving and frost protection, which can be set using the touch buttons. The device has a functional design. It was made of durable plastic. Like all other devices offered by Siemens, it has all the necessary certificates confirming the highest quality of workmanship.

The RDE100.1DHW Siemens controller consists of two parts:

  • Housing made of plastic, in which there are electronic systems, operating elements and a built-in room temperature sensor
  • Mounting base

The housing snaps into the mounting plate and is secured with a screw.
