3.5 D.h.w. heating modes
D.h.w. heating is switched on and off by pressing the respective button:
 ON (button
is lit): D.h.w. heating takes place independent of the
heating circuit’s operating mode and control. D.h.w. can be heated in
one of 3 different ways:
 According to the scheduler program 2 entered
 According to the heating circuit program entered (–1 hour)
 Continuously (24 hours a day)
During the holiday period entered, d.h.w. heating and the circulating
pump are deactivated when using controllers without bus connection
(RVP351) (with data bus, depending on the setting made).
 OFF (button
dark): No d.h.w. heating. Frost protection is ensured
 Solar d.h.w. heating is always released, independent of the d.h.w.

3.6 Manual control
RVP3.. controllers can be switched to manual control. In that case,
automatic control is deactivated.
During manual control, the various actuating devices behave as follows:
 Heating circuit mixing valve/2-port valve: Dead, but valve can be con-
trolled manually with the buttons for manual control
( and ):
3-position actuators: Can be driven to any position by pressing
(close) and
(open).
2-position actuators: Power supply to the actuator can be switched on
by pressing
and off by pressing
 Heating circuit pump M2 runs continuously
 Boiler: The 2 burner stages are continuously on. Circulating pump M1
runs continuously
 Storage tank charging pump M3: Runs continuously
 Collector pump: Runs continuously
 Circulating pump K6: Runs continuously
 Electric immersion heater: Continuously released
Manual control also negates any overriding of the controller's operating
mode (bridging of H1–M).
