Installation Guide
A367.1, example e
Indirectly connected system with 2 heating circuits (1 connected as sub circuit) and primarily connected DHW tank with internal
heat exchanger (optional DHW priority).
Special settings for type A367.1, example e:
Heating circuit 1
Heating circuit 1 must receive information about and react on the desired flow temperature from heating circuit 2.
Navigation:
MENU \ Settings \ Application: 'Demand offset'
*
The desired flow temperature in heating circuit 1 is 5 K above the desired flow temperature in heating circuit 2.
Heating circuit 2
Heating circuit 2 is connected secondarily and must send information about its desired flow temperature to heating circuit 1.
Navigation:
MENU \ Settings \ Application: 'Send desired T'
DHW circuit (circuit 3)
The DHW heating is controlled by means of ON / OFF valve** P2 / M3.
Navigation:
MENU \ Settings \ Application: 'Ch.-o. valve / P'
The DHW tank is connected secondarily.
MENU \ Settings \ Application: 'Tank, sec./prim.'
**
The ON / OFF valve can be of different types:
A:
Normal power supplied. When the control voltage is applied (from terminal 12), the ON / OFF valve fully opens the flow.
Example: Danfoss AMZ 112.
B:
3–point controlled actuator. The control of the M3 actuator follows the control of the P2 output. An OPEN command (from terminal 2) or
a CLOSE command (from terminal 1) is constantly applied to actuator M3 in order to fully open or fully close the flow.
Example: actuator / valve: Danfoss AMV / VS 2 - VZ 2 - VRB 2.
