Quick heat-up:
Only possible when room control
module RRG is connected and room sensor active.
Quick heat-up/quick reduction is effective only when
the heating circuit is switched over from frost
protection or reduced mode to standard operation
and the room temperature is simultaneously more
than 1.5
°
C below the room temperature setting (even
when room temperature setting is increased on room
control module).
Quick heat-up is terminated when the room
temperature is less than 0.25
°
C below the room
temperature setting,
Rapid reduction (with room sensor):
When the
heating circuit is switched over from Standard mode
to Reduced mode or Frost protection mode, the rapid
reduction feature is active (heating circuit pump is
switched off).
Boiler frost protection:
On systems with outdoor
temperature sensor, the system frost protection
feature is switched on and off by the outdoor
temperature. In this case the heating circuit pump is
switched as follows:
Outdoor Temperature

Continuous operation pumps ON
Pumps on for 10 min. every 6 hours
Pumps OFF
Building Frost Protection:
The building is protected against frost in all operating
modes:
- Room control module RRG (with effective room
sensor): The frost protection room temperature
setpoint is effective in all modes.
-
Heating circuit module HKM with timer EMS or
room control module RRG (without effective room
sensor): The building frost protection is ensured by
the heat requirement in the Standard and reduced
mode.
- Room thermostat
RAV/RTW/RTD: Building
frost protection is ensured by the heat requirement
from the room thermostat.
Hot Water Frost Protection:
The tank is protected
against freezing because the tank is automatically
charged when the temperature drops below the
setting.
Restart Inhibit (burner starts):
To reduce the
number of burner start-ups, the boiler is equipped
with a start-up inhibit of 3 min.
Anti-Legionnaires disease function (only with
room control module RRG):
Heat-up is started
once a week on Monday with the first hot-water
charge and lasts for a maximum of 2.5 hours. In the
“Stand-by” mode, the function is inhibited. If it is
inhibited for longer than 1 day, the anti legionnaires
disease function is repeated as soon as the hot water
is enabled.
Chimney Sweep Function:
The so-called “Chimney
Sweep” function can be activated by pressing the
Chimney Sweep button (12) (>3 sec) (fault display (8)
flashes once
). The burner is switched on and heats
up the PARAMOUNT at the maximum boiler output
until the temperature monitor trips at 82
°
C.
Note: “SF” appears on display (13) and the fault
indicator (8) flashes!
Deactivation of Chimney Sweep function:
Press
the Chimney Sweep button (12) (min 1 sec) to
deactivate the chimney sweep function.
Emergency Operation Functions:
In the event of
component failure, an error message is output (see
Table 11) leading to start-up prevention and
emergency operation function, however not to fault
switch-off.
Moreover, emergency operation is accomplished in
the event of the following faults:
•
Hot water mode:
Defective tank sensor: The hot water mode is
inhibited, heating operation for the heating circuit is
still ensured.
Defective room control module RRG or heating circuit
module HKM: The hot water temperature is regulated
to the value set on the boiler module under
parameter “P2”.
•
Heating mode:
Defective outdoor temperature sensor: In the event
of a defective outdoor temperature sensor, the
system is regulated to a boiler temperature
corresponding to an outdoor temperature of 0
°
C.
