Heating circuit 2 can alternatively be a floor heating circuit.<br />
At DHW heating P3 is switched ON and the desired boiler temperature is a number of degrees above the desired DHW temperature.<br />
P1 is switched OFF.<br />
Heating circuit 2 can be closed during DHW heating.<br />
Special settings for type <strong>A275</strong>.3, example d:<br />

Navigation: ID no.: Recommended setting:<br />
Heating circuit (circuit 1)<br />
Circuit 1 must be able to receive a heat demand (desired flow temperature) from circuit 2:<br />
MENU \ Settings \ Application: 'Demand offset' 11017 3 K**<br />
** This value is added to the heat demand value from circuit 2<br />
Heating circuit (circuit 2)<br />
Circuit 2 must be able to send a heat demand (desired flow temperature) to circuit 1:<br />
MENU \ Settings \ Application: 'Send desired T' 12500 ON<br />
Circuit 2 can be closed during the DHW heating process:<br />
MENU \ Settings \ Application: ‘DHW priority' 12052 ***<br />
*** Set 'OFF' when not to be closed, set 'ON' when to be closed<br />
DHW circuit (circuit 3)<br />
DHW heating is managed by pump P3:<br />
MENU \ Settings \ Application: 'Ch.-o. valve / P' 13051 ON<br />
The desired DHW heating temperature must influence the boiler temperature:<br />
MENU \ Settings \ Application: ‘Tank, sec./prim.' 13053 OFF<br />
