PARAMOUNT
545 (ZbreMinP) Minimum pause time for burner:
The PARAMOUNT is provided with a minimum
pause time or start-up disable of 2 min. to reduce the
number of burner start-ups.
547 (ZreglVerz) Delay after burner start-up: The
controller delay time after burner start-up is set to 60
sec. This should not be re-adjusted to ensure
reliable burner operation! During this time, the
PARAMOUNT is operated at the boiler output set in
program No. 598 (LmodRgVerz)
551 (Kon) Constant for quick reduction: This
function switches off the heating circuit pump when
the system is switched over to a lower room
temperature setting (e.g. night set back/reduction).
This function is provided for systems operated with
an outdoor temperature sensor or without room
control module. The switch-off time for the heating
circuit pump is set as specified in Table 9 by entering
a constant (Kon). The heating circuit pump is
switched off for a maximum of 15 hours. At outdoor
temperature below -5°C, the pump is not switched
off.
Note: Low "constant" for "lightweight" buildings which
cool down quickly
High "constant" for "heavy" well insulated buildings.

552 (HydrSystem) Hydraulic system setting: The
hydraulic system is set to "2" at the factory i.e. the
PARAMOUNT can be used for the max. possible
number of hydraulic systems. However, in order to
ensure optimum heating operation for application

indicated by the designation "On" or "Off"!
555 (KonfigRg1) Bit setting for hot-water priority:
555.0 Off: Absolute priority (factory setting)
555.0 On: Sliding priority
555.1 On: No priority (parallel operation)
Depending upon the setting the heating circuit is
limited while hot water is heated.
At the factory, absolute priority is set for CTC.
When sliding priority is set and the heating capacity
of the PARAMOUNT is not sufficient, the heating
circuit is limited accordingly until the hot demand is
satisfied.
not recommended. This setting applies for all
heating circuits.
Bit setting for terminal assignment N5:
555.2 Off: Room thermostat (factory setting)
555.2 On: Timer
Factory setting: room thermostat: The switching
state of the room thermostat contact is decisive for
the heat demand. When the contact is open, the
heat demand is inhibited, when the contact is
closed,
temperature thermostat acts on the PARAMOUNT.
0
The pump is switched on and off according to the
heat demand (with switch off delay).
If N5 is set to the timer function, in the reduced
mode (timer contact open) the room temperature
setting is reduced by the value set in program
no.520 (dTrAbsenk) by 10K (factory setting). The
pump runs in standard mode and in reduced mode
except for quick reduction.
Note: When program no. 520, code = 0, the heating
mode is switched off completely when the timer
contact is open.
