Room control unit for room automation RYMASKON® 400 - Modbus
RYMASKON® stands for a series of multifunctional room control units. The individually configurable RYMASKON® 400 - Modbus controller enables automated monitoring and control of indoor climate and illumination in a Modbus network. It has two digital inputs and two digital/analogue outputs. Room climate control and regulation can be accessed from a central point on a higher-level Modbus master, and on-site operation can be selectively or completely disabled. Thanks to its internal outputs, the inputs and settings on the device do not necessarily have to be processed by the master. This means that it is also possible to have decentralised individual room control at any time. An internal sensor detects the room temperature.

Six freely assignable function buttons on the front panel of the unit can be used for on-site operation and configuration. An integrated rotary encoder with a central input button enables manual adjustment of settings and parametre assignment on site Desired functions (such as "Light ON") and display values can be activated by means of a proximity sensor when entering the room.
The dimmable multifunctional display has been designed specifically for room operation and uses intuitive icons for a clear view of all available room data. Besides time, weekday and climate parametres (temperature, humidity, dew point, CO2 content), the room operation unit can also display additional features, such as heating/cooling and fan modes, window open, lighting, alarm, key lock or room occupancy.
