If the operating temperature drops below
I08
- (
I19
: 2) -
I21
-
I18
, the electric resistance (DO2) starts and the fan starts
at speed 1. The speed increases as the operating temperature drops, reaching speed 3 when the operating temperature
falls below
I08

Icon
turns on.
If the operating temperature increases to
I08
- (
I19
: 2) -
I21
-
I18
the speed remains constant at speed 1 until the op-
erating temperature exceeds
I08
- (
I19
: 2) -
I21
.
Icon
turns off.
if
I28
=0 or 2, the fan stops after delay
I35
.
if
I28
=1 or 3, the fan stays on at speed 1.
if
I28
=4 or 6, the fan stays on at speed selected manually.
If the operating temperature rises above
I08
+ (
I19
: 2), the cooling stage is activated and fan starts at speed 1, after
startup delay
I36
. The speed increases as the operating temperature increases, reaching speed 3 when the operating
temperature exceeds
I08
+ (
I19
: 2) + [
I27
x (FB -
I19
)].
Icon turns on.
If the operating temperature falls to
I08
+ (
I19
: 2) the fan stays at speed 1 until the operating temperature drops below
I08
- (
I19
: 2).
Icon turns off and cooling stage is deactivated.
if
I28
=0 or 3, the fan stops,
if
I28
=1 or 2, the fan stays on at speed 1.
if
I28
=4 or 5, the fan stays on at speed selected manually.
