VITOSOL
Cylinder 2 ON
This function enables a second consumer
(e.g. calorifier or swimming pool) to be
taken out of the control unit.
Break or short circuit of cylinder
temperature sensor T
cyl2u
is no longer
notified.
DHW loading
This function enables a given physical
range of the DHW cylinder to be heated,
defined through the sensor location.
This function is achieved via two
thermostats or one relay.
Additional function for DHW heating
Additional function in conjunction with Vitotronic control units and KM BUS
At the boiler control unit,
H a second set DHW cylinder temperature
must be encoded
H the fourth DHW phase for DHW loading
must be activated.
This signal is transferred via the KM BUS
to the solar control unit, and the
circulation pump will be started.
Additional function in conjunction with additional Viessmann control units
The circulation pump (relayering pump)
is started at an adjustable time, if the
DHW cylinder has not been heated to
60ºC at least once every day.
A DHW temperature of approx. 35 ºC is
simulated via a resistor.
