Siemens Heating and D.h.w. Controller RVL481 CE1P2541en
Building Technologies 3 Fundamentals 20.05.2008
Precontrol with heat exchanger
Precontrol with district heat connection, with demand-compensated control of the sec-
ondary flow temperature acting on the valve in the primary return.
Heat demand signal from data bus. No heating program.
Can be combined with d.h.w. types:
• with types 1 and 2 via hydraulic connection at
and
• with type 5 without hydraulic connection
