The customer is always right and, in many cases the customer prefers analogue controls.
So Theben has added a surface- mounting controller with traditional clock and rotary controls to its range of OpenTherm compatible devices. At its heart, if course, is a digital microprocessor.
The unit regulates temperature by room sensing or weather compensation. As well as room heating the RAMSES 786 OT will control hot water temperature. It is suitable for radiators and underfloor heating
No mains power required, data is transferred and power drawn via an extra low voltage OpenTherm bus via an OpenTherm compatible boiler.
