Additional specifications and description
How Is Fan Speed Adjusted and Displayed in Manual and Automatic Modes?
In manual mode, the fan speed can be adjusted steplessly or in 2-10 steps. The fan speed can be manually set via the up and down arrows. By pressing the select button with the green check mark for 4 seconds, the motor can be activated or deactivated. The selected fan speed is visualised via the 7-segment LED display (% or step number).
How Does the Controller Utilize Modbus RTU Communication?
The motor can be accelerated in softstart or in kickstart mode. In softstart mode, the motor will accelerate smoothly towards the set fan speed. In kickstart mode, the motor will immediately start running at full speed and slow down towards the set fan speed after a few seconds.
How to configure this fan speed controller?
The controller features Modbus RTU communication. As standard, Sentera devices with Modbus RTU on board can be set up using the free 3SModbus software. Modbus RTU holding registers duplicate the functions selected via the keyboard interface. If you choose to make use of this functionality, you will have access to the complete set of features offered by the RDCZ using your computer.
How and Where Is the Controller Mounted?
The enclosure allows surface mounting or inset mounting. When built-in a wall, it offers an IP44 protection against the ingress of dirt and dust. For surface mounting, the protection degree is IP54.

You can install the RDCZ on and in all kinds of walls – solid, gypsum board or wooden panels. If you opt for inset installation, the mounting holes fit perfectly the standard European wall boxes used for inset mounting. All you need is a couple of every day tools – screwdrivers and pliers, a little bit of general knowledge and handiness.
