3.2.7 Heating circuit type 6 – precontrol with district heat
Y1
B7
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.
3.2.8 D.h.w. plant type 0 – no d.h.w.
The RVL471 does not provide d.h.w. heating.

valve
Y7
B3
M3
K6
Charging of d.h.w. storage tank through control of the mixing valve according to own
temperature sensor in the storage tank flow. Acquisition of the d.h.w. temperature with
one or 2 sensors or thermostats. Circulating pump and electric immersion heater are
optional.
