Control panel
Refer to figure 2 to catch the look of the controller.
Temperature range
The print around the selector switch of the thermostat
represents temperature ranges from minimum, over
comfort, to maximum. The ranges refer to different
temperatures, depending on the selected operating
mode as illustrated in the figure below.
LED indicators
The various combinations in which the LED lights up
indicate procedures and operating status of the
controller.
■
Blue LED lit
indicates that the cooling mode is
running. The unit is running or waiting for an input
from the thermostat.
■
Red LED lit
indicates that the heating mode is
running. The unit is running or waiting for an input
from the thermostat.
■
Blue and red LEDs lit
indicates that the unit did not
receive an enabling signal. The water temperature
does not enable the air cooling or heating functions
(see "Automatic cooling/heating switching mode
based on the water temperature" on page 3) or the
temperature of the air is within the neutral zone (see
"Automatic cooling/heating switching mode based on
the air temperature" on page 4).
■
Double flashing of the blue LED
means that the
thermostat has sent an input to the unit for starting
cooling mode. It flashes when the room temperature
and the set cooling temperature are the same.
■
Double flashing of the red LED
means that the
thermostat has sent an input to the unit for starting
heating mode. It flashes when the room temperature
and the set heating temperature are the same.
The temperature of the air in the room can be seen at
any time on the thermostat range turning the knob of the
thermostat.

When automatic cooling/heating switching
mode based on the air temperature is running,
the temperature of the thermostat is as
illustrated in figure 3.
NOTE
To determine which operating mode is
selected when an enabling signal is
missing (blue and red LEDs are both lit),
turn the knob of the thermostat until one of
the two LEDs starts to flash and then
remains lit. This LED points out the
selected operating mode. Once the
operating mode has been established, turn
the thermostat back to the desired
position.
