REMKO VRS-C Series
Mode of operation
After switching on the units by
pressing the “Heating” selector
switch, the forced-air burner
switches on.
The lamp on the “Heating”
selector switch lights up as an
indicator.
The combustion chamber with
heat exchanger is now heated up.
When the setpoint temperature
is reached, the supply air fan
switches on automatically.
The “Fan” operating lamp on the
ventilation selector switch lights
up.
Warm air is blown out.
When operating with a room
thermostat, this process is repeated
automatically depending on the
heating requirement.
The controller unit and the
automatic burner (component of
the forced-air burner) execute all
unit functions fully automatically
and ensure reliable monitoring.
After switching off the units
via the operating switch or the
room thermostats, the supply air
fan runs to cool the combustion
chamber and the heat exchanger
for a certain time and then
switches off automatically.
In the event of irregularities or
if the flame is extinguished, the
automatic burner switches off and
interlocks the burner.
The automatic burner fault lamp
and the red “burner” fault lamp
light up.
The units can only be restarted
after manually resetting the
automatic burner.
The safety temperature limiter
(STB) interrupts the burner
function in the event of
overheating.
Manual resetting of the STB can
only be implemented after the unit
has cooled down.
The units may never be
disconnected from the mains
prior to the completion of the
follow-up cooling phase (ex-
cept in emergencies).
CAUTION
NOTE
Before resetting the automatic
burner relay or safety thermal
cut-out, first always determine
the causes of the fault shut-
down.
