Instructions for the user
Fault displays
A green and red LED are installed
on the front of the unit.
The illumination of the green LED
means that the unit is connected
to the mains. The illumination
of the red LED indicates a
malfunction of the unit.
The cause of the malfunction
can be immediately identified by
the different types of flashing /
illumination of the red LED:
F1 - LED continuously lit
F2 - LED flashes twice quickly
F3 - LED flashes three times
quickly
F4 - LED flashes four times quickly
F8 - LED flashes continuously
F6 - red and green LED blink
alternately
The faults (lock-outs) displayed
and saved by the control PCB have
the following causes:
F1 - malfunction of the flame
monitoring unit because
of unsuccessful ignition
of the burner; the control
PCB arranges for a series
of automatic deactivation
attempts prior to reporting the
malfunction.
F2 - malfunction of the safety
thermostat. If the temperature
detected by the thermostat
is set too high, it disconnects
and disables the operation of
the unit.
F3 - Burner fan defect;
combustion air fan is defective
or the signal to the control
PCB lies beyond the tolerance
range of the desired speed.
Summer/winter conversion
The units are equipped with a
single-pole toggle switch on the
front side, which enables it to be
switched from winter operation
(with active heating) to summer
operation (only ventilation).
By switching on one of the two
operating modes the units can
be used for both heating or air
circulation on warmer days.
To switch on the winter phase, the
toggle switch only needs to be set
to the winter symbol.
To switch on the summer phase,
the toggle switch only needs to be
set to the summer symbol.
The contacts 7-8-9 of the terminal
block M1 in the burner cabinet
are responsible for these modes of
operation.
These contacts can also be
repositioned in the room by the
installer.
See the instructions for the installer
for the electrical connections.
The safety notes on the preceding
pages must be observed without
fail.
The activities of the user are
limited solely to the actuation of
the switches for operation of the
unit.
A brief description of the modes
of operation of the units with and
without accessories follows.
Operation without
accessories
This mode of operation is available
with every unit. It is a mode of
operation that enables immediate
operation.
Switching on and off
The procedures for switching on
and off take place by closing and
opening the contacts 7-9 of the
terminal block M1, which is found
in the switch cabinet.
The units may never be
disconnected from the mains
prior to the completion of
the follow-up cooling phase
(except in emergencies).
ATTENTION
For the correct mode of the
summer/winter operation of
the unit with a swapping of
the contacts in the room, the
single-pole toggle switch on
the unit must be set to winter
operation.
ATTENTION
For correct operation it is
necessary to connect at least
one room thermostat in
order to be able to switch the
burner on and off.
