Engineering notes
See the “Reference documentation”, page 14, for information on how to select and dimension connecting cables for supply voltage and field devices

Mounting and installation

Mount the room thermostat on a conduit box. Do not mount on a wall in niches or between bookshelves, behind curtains, above or near heat sources, or exposed to direct solar radiation. Mount about 1.5 m above the floor.

SIEMENS-RDD810-Flush-mount-touch-screen-room-thermostat-Product-Specifications-FIG-34Mounting / Dismounting

  • Do not apply excessive force on screws! The deformation of the mounting frame may lead to improper connections and operation of the unit.
  • Mount the room thermostat on a clean, dry indoor place without direct airflow from a heating / cooling device, and not exposed to drips or water.
  • Before removing the front cover, disconnect the power supply.

Wiring See the User Manual for the installation instructions enclosed with the thermostat.

  • SIEMENS-RDD810-Flush-mount-touch-screen-room-thermostat-Product-Specifications-FIG-34Comply with local regulations to wire, protect and earth the thermostat.
  • SIEMENS-RDD810-Flush-mount-touch-screen-room-thermostat-Product-Specifications-FIG-34The device has no internal fuse for supply lines to fan and actuators. To avoid risk of fire and injury due to short-circuits, the AC 230 V mains supply line must have a circuit breaker with a rated current of no more than 10 A.
  • SIEMENS-RDD810-Flush-mount-touch-screen-room-thermostat-Product-Specifications-FIG-34The wiring cross section used for power supply (L, N) and 230 V outputs (Qxx – N) must be adapted to the preceding overload protection elements (max 10 A) under all circumstances. Comply under all circumstances with local regulations.
  • SIEMENS-RDD810-Flush-mount-touch-screen-room-thermostat-Product-Specifications-FIG-34Properly size the cables to the thermostat and valve actuators for AC 230 V mains voltage.
  • SIEMENS-RDD810-Flush-mount-touch-screen-room-thermostat-Product-Specifications-FIG-34Cables of SELV inputs X1-M / X2-M: Use cables with min 230 V insulation, as the conduit box carries AC 230 V mains voltage.
  • SIEMENS-RDD810-Flush-mount-touch-screen-room-thermostat-Product-Specifications-FIG-34Inputs X1-M or X2-M of different units (e.g. window contact) may be connected in parallel with an external switch. Consider overall maximum contact sensing current for switch rating.
  • SIEMENS-RDD810-Flush-mount-touch-screen-room-thermostat-Product-Specifications-FIG-34No cables are provided with a metal shield.
  • SIEMENS-RDD810-Flush-mount-touch-screen-room-thermostat-Product-Specifications-FIG-34Disconnect from supply before opening the cover
