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 control
thermostat connected to B3.
When using a DHW control thermostat, Reduced mode is not possible. This means that
when Reduced mode is active, DHW heating with the control thermostat is locked.
• The adjustment of the nominal DHW temperature setpoint must be equal to or higher
than the setpoint adjustment on the control thermostat (thermostat calibrated at
switch-off point)
• The flow temperature setpoint for DHW must be set to a minimum of 10 °C (with
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 heated up with a pump connected to terminals Q3 / Y3.
Diverting valve
The DHW is heated up with a diverting valve connected to terminals Q3 / Y3. With this
setting, pump Q2 becomes a boiler pump, provided the boiler pump is not yet defined
for use at a multifunctional relay output QX...
