REMKO VRS EN Series
Mode of operation
After connecting the unit to the
mains, the phase indicator lamp
H1 on the control box illuminates.
The fan burner is switched on
by pressing the heating selector
switch. The heating signal lamp
built into the heating selector
switch illuminates.
The combustion chamber with
heat exchanger is now heated up.
When the setpoint temperature
is reached, the supply air fan
switches on automatically. The
setpoint temperature is specified
by the fan controller TR.
The ventilation signal lamp in
the ventilation selector switch
illuminates. When the setpoint
temperature is reached, the fan
cannot be switched off by the
ventilation selector switch.
When operating with a room
thermostat, this process is repeated
automatically depending on the
heating requirement.
The controller unit and the
automatic burner execute all unit
functions fully automatically and
ensures reliable monitoring.
When the burner function is
enabled by the controller unit and
the room thermostat, the burner
operating lamp on the control box
illuminates.
After switching off the units via
the heater selector 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 burner fault lamp of the
automatic burner relay and the red
burner fault lamp on the control
box illuminate. 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. In this case, the
burner is disconnected from the
mains, the fan continues to run for
post-cooling. Manually resetting of
the STB can only be implemented
after the unit has have cooled
down.
The fan motor is monitored by a
thermal cut-out (TMC). If this is
triggered, the complete circuit of
the burner is also interrupted. In
this case, the motor indicator lamp
on the control box extinguishes.
The units may never be
disconnected from the mains
prior to the completion of
the follow-up cooling phase
(except in emergencies).
CAUTION
NOTE
Before resetting the automatic
burner relay or safety thermal
cut-out, first always determine
the causes of the fault
shutdown.
