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.
