DHW sensor B3
Sensors
Thermostat
Sensors
The collector calculates the switching points including the switching differential from the
DHW setpoint and the acquired DHW storage tank temperature.
Control thermostat
The DHW temperature is controlled based on the switching state of a thermostat
connected to B3.
When using a DHW thermostat, Reduced mode is not possible. This means that when
Reduced mode is active, DHW heating with the thermostat is locked.
· The adjustment of the nominal DHW temperature setpoint must be equal to or higher
than the setpoint adjustment on the thermostat (thermostat calibrated at switch-off
point)
· The flow temperature setpoint for DHW must be set to a minimum of 10 °C (has an
impact on the charging time).
· In that case, the DHW is not protected against frost.

No DHW charging via Q3.
Charging pump
The DHW is charged with a pump connected to terminal Q3/Y3.
Diverting valve
The DHW is charged with a diverting valve connected to terminals Q3/Y3. With this
setting, pump Q2 becomes a heat generation pump, provided the heat generation
pump is not yet defined for use at a multifunctional relay output QX...
