A367.2, example b
Indirectly connected system with 2 heating circuits and secondarily connected DHW charging system (DHW priority).
Special settings for type A367.2, example b:
DHW circuit (circuit 3)
The DHW heating is controlled by means of changeover valve* P2 / M3.
Navigation:
MENU \ Settings \ Application: 'Ch.-o. valve / P'
*
The changeover valve can be of different types:
A:
Normal power supplied. When the control voltage is applied (from terminal 12), the changeover valve changes flow direction.
Example: Danfoss AMZ 113.
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 determine the flow direction.
Example 1: actuator / valve: Danfoss AMV / VMV — VRB3 — VRG3.
Example 2: actuator / valve: Danfoss AMB / HRB 3 — HFE 3.
