During DHW heating, the circulation pump P1 in the heating circuit
can:
• be switched OFF (DHW priority mode)
or
• remain ON, as long as the heating temperature at S3 does not
differ more than a set value from the desired temperature
(dependent parallel mode)
or
• be continuously ON. This means same temperature in the
heating circuit as the DHW heating temperature (parallel
mode).

The flow / power signal can come as a pulse signal or an M-bus
signal.
A337.1
The desired flow temperature of the heating circuit can, via S10, be
controlled by means of an external voltage in the range 0 - 10 volt.
Modbus communication to a SCADA system can be established.
A connected flow or energy meter based on M-bus signal can
limit the flow or power to a set maximum value. Furthermore, the
limitation can be in relation to the outdoor temperature.
Typically, the lower the outdoor temperature, the higher the
accepted flow / power.
M-bus data can be transferred to the Modbus communication.
Heating in general
Exercise of circulation pumps and control valve in periods without
heating demand can be arranged.
