OpenTherm interface for KNX: KNX-OT-Box
With the new KNX-OT-Box Theben is breaching the gap between two worlds: KNX and OpenTherm heaters can be linked via this universal interface. It can be used as the master for the OpenTherm heater in combination with a KNX individual room control.
A summary of the highlights of OpenTherm interface for KNX:
-
OpenTherm and KNX
The new interface from Theben links the KNX BUS with the OT BUS widely used with gas water heaters. As a master, the KNX-OT-Box enables the bidirectional exchange of data between the OpenTherm heater and the heat distribution via the KNX system for individual room control. -
Simple to use via multi-functional display
The VARIA 826 KNX multi-functional display can be used to set and change settings for the boiler control. They are transmitted to the OpenTherm heater via the KNX-OT-Box. -
Pilot room control
The new interface now not only enables pilot room control but also maximises feed as required for all rooms. -
Energy saving service water heating
Heating domestic water with a solar power system helps save energy as the amount of sunshine expected according to weather forecasts can be taken into account when heating water. Beyond that, the energy-optimised legionella protection prevents unnecessary heating of the storage tank to the legionella protection temperature. -
Screed drying program
The Theben KNX-OT-Box can be easily and quickly set up using removable bus coupling units and the factory preset "screed drying program as per DIN EN 1264-4".
