A275.3, example d
Boiler ON / OFF control for a direct heating circuit (1), a mixing circuit (2) and a DHW circuit (3). Optional DHW priority. The mixing circuit
(2) is controlled by means of a 4-port mixing valve.
* = pressure relief valve
Heating circuit 2 can alternatively be a floor heating circuit.
At DHW heating P3 is switched ON and the desired boiler temperature is a number of degrees above the desired DHW temperature.
P1 is switched OFF.
Heating circuit 2 can be closed during DHW heating.
Special settings for type A275.3, example d:
Navigation:
Heating circuit (circuit 1)
Circuit 1 must be able to receive a heat demand (desired flow temperature) from circuit 2:
MENU \ Settings \ Application: 'Demand offset'
** This value is added to the heat demand value from circuit 2
Heating circuit (circuit 2)
Circuit 2 must be able to send a heat demand (desired flow temperature) to circuit 1:
MENU \ Settings \ Application: 'Send desired T'
Circuit 2 can be closed during the DHW heating process:
MENU \ Settings \ Application: 'DHW priority'
*** Set 'OFF' when not to be closed, set 'ON' when to be closed
