Room Control Module RRG (Fig 8)
With the room control module (optional extra) you
can
-
control the functions from the room (remote
control)
-
make settings (e.g. your own timer programs)
-
call up information (e.g. temperature values)
etc.
All possibilities are described in the instructions
included with the room control module. Only a few
of the most important functions are described
below.
Presence Button
With the Presence button you can manually
manipulate the set timer program (heating
program):
-
“Sun” symbol: Heating operates at set
temperature.
-
“Moon” symbol: Heating operates at reduced
temperature
The Presence button is effective until the timer
program switches the next time.
The Presence button has no effect on the hot water
heating!
Temperature Knob
You can readjust the set temperature with the
temperature knob. One increment corresponds to
approx. 1
°
C. Before changing the temperature
setting on the temperature knob, set the
thermostatic valves to the desired temperature.
Correct again only after the temperature has
adapted.
Temperature Sensor in Room Control Module
The temperature sensor integrated into the room
control module is effective only when the room
influence is enabled on the PARAMOUNT.

SERVICE
Cleaning:
The heat exchanger and burner should
be cleaned by a certified gas installer. Before
starting the work, shut off the gas shut-off device
and the hot water shut-off valves and disconnect all
power to the boiler.
Condensate Trap:
The condensate trap should be
cleaned every one to two years. For this purpose,
loosen the threaded fitting on the trap and pull the
trap off downward. Completely remove the trap
together with hose from boiler, disassemble and
rinse with clear water. Reinstall the trap in the
opposite order.
Replacing Air Vent:
Ensure that the air vent is
replaced only with genuine replacement part when
defective to ensure optimum venting!
Removing Gas Burner:
Burner: Before cleaning
the heat exchanger, remove the gas burner. For
this purpose, disconnect the electric connections to
the fan at the plug connector, pull the air hose off
the fan and disconnect the plug from the
electrodes.
•
Remove silencer
•
Disconnect threaded fittings for gas connection
pipe on mixing duct and on gas valve. Remove
gas connection pipe and gas injector. Loosen
the 5 mounting nuts on the mixing duct/heat
exchanger. Pull burner out toward front
together with mixing duct and fan.
•
Clean burner pipe with soft brush.
When installing, use new gaskets, particularly for
the gas connection pipe.
