Reset is carried out automatically
if the number of events per hour
is equal to parameter A02, other-
vise it switches to manual.
Not active when time Pa A01 is
counted after a compressor is tur-
ned on or the 4-way valve (rever-
sing valve) is reversed.
Inactive during defrosting if Pa
24 = 0
E03
Thermal switch

Triggered by the digital input
configured as “Compressor 1
thermal switch” (see digital
inputs)
OFF ON
Automatically reset unless alarm

Pa A18 parameter selects the
alarm probe: Pa A18 = 0 AI1,
Pa A18 = 1 AI2.
External fans and compressors
will be shut down;
Active if analogue probe
selected (see analogue inputs)
is configured as NTC probe (Pa
H06=1 or Pa H07=1);
Triggered when probe AI5
detects a value below Pa A11;
Goes off if the probe detects
a value greater than Pa A11 +
Pa A12.
OFF
Reset is carried out automatically
if the number of events per hour
is equal to parameter A09, othe-
rwise it switches to manual.
In Heating mode, it is not active
while the Pa A10 time is counted
from start-up of the unit with
ON-OFF button (see keyboard)
or with ON-OFF digital input (see
digital inputs)
