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.

Domestic water
DHW
The Paramount 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.
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.
Time programs HCs: The DHW temperature will be switched over
between the nominal DHW temperature value and the reduced nominal
DHW temperature value depending on the time programs. Every time,
the switching-on time is moved forward.
It is moved forward by 1 hour.
Time program 4/DHW: The DHW temperature is changed over between
the DHW temperature setpoint and the reduced DHW temperature
setpoint independently of time programs of the heating circuit. For this,
time program 4 is used.
Charging priority (1630)
This function ensures that the boiler capacity is primarily made available
for DHW in case of simultaneous capacity demand by room heating and
DHW.
Absolute: Mixer and pumped heating circuits are blocked until the DHW
has been heated up.
Shifting: Should the boiler capacity not be sufficient to heat up DHW,
mixer and pumped heating circuits will be restricted.
None: Charging DHW is carried out in parallel with heating operation.
