Even in today’s digital age some customers will prefer analogue controls, so Theben has added a surface mounting controller with traditional clock and rotary controls to its range of Opentherm compatible devices. The RAMSES 786 OT still contains a digital microprocessor and the unit is capable of regulating temperature by room sensing or weather compensation and can control hot water as well as room temperature. The unit is also suitable for both radiators and underfloor heating.
