Pump speed max (883, 1183, 1483)
The maximum speed for the heating circuit pump can be specified using
this function.
Curve readj at 50% speed (888, 1188, 1488)
Correction of the flow setpoint with reduction of the pump speed by 50%.
The correction is calculated using the difference from the flow setpoint
according to the heating curve and current room setpoint.
Flow setp readj speed ctrl (890, 1190, 1490)
Here it can be specified whether the calculated flow setpoint correction is
included in the temperature request or not.
No: The temperature request remains unchanged. The calculated
correction value is not added.
Yes: The temperature request includes the flow setpoint correction.
Operating level changeover (898, 1198, 1498)
When an external timer is used above the inputs
Hx
selection of the
operating level to which the heating circuits are to be switched is possible.
Protection

Optg mode changeover (900, 1200, 1500)
With external change of operating mode via Hx it can be selected whether
during automatic operation it is changed from comfort set point to the frost
prevention setpoint or reduced setpoint.

DHW
The EC five controls the domestic water temperature in accordance with
the time program or continuously to the setpoint required in each case.
The priority of the domestic water charging relative to the room heating
can be set here. The controller has an adjustable Legionella function,
which prevents Legionella in the storage tank and in the circulation line.
The circulation pump is regulated to the required setpoint in accordance
with the selectable time program and operating mode.
Operating mode (1600)
The domestic hot water charging can be switched to On, Off or Eco mode
using "operating mode".
Off: The DHW is kept permanently at frost protection temperature (5°C).
On: The DHW charging is done automatically to the DHW nominal
setpoint or the DHW reduced setpoint based on the set DHW release.
Nominal setpoint (1610)
Setting the drinking water nominal value
Reduced setpoint (1612)
Setting the DHW reduced setpoint.
Nominal setpoint max (1614)
Set the maximum permissible DHW nominal value.
Release (1620)
24h/day: The DHW temperature will be continuously controlled to the
nominal drinking water temperature value independent from the time
programmes.
