E31
High pressure
circuit 2 on
analog input
Compressors in circuit 2 will be shut down;
Active when Circuit 2 pressure sensor detects a value greater then
Pa A14
;
Inactive if the sensor detects a value lower then
Pa A14 – Pa A15
;
E32
Low pressure
circuit 2 on
analog input
Compressors
in circuit 2 will be shut down, as well as condenser fans if the 2 circuits
have separate condensation (refer to
combined or separate condensation
);
Active if the analog probe ST6 (refer to analog inputs) is configured as pressure probe;
Active when the pressure probe ST6 detects a value lower then
Pa A17
;
Inactive if the probe detects a value greater then
Pa A17
–
Pa A18
;
Automatically

until
alarm events per hour
reaches the value of parameter

Entering Water
Temperature
Sensor fault
All loads will be shut down;
Input shorted or open circuit or probe limits are exceeded (-50°C.. 100°C).
E41
Flow switch
All compressors, fans and pump will be cut off if manually reset;
Triggered if the “Flow switch” remains active for an amount of time equal to
Pa A04
;
Goes off if “Flow switch” remains inactive for an amount of time equal to
Pa A05
;
Automatically reset until alarm events per hour reaches the value of parameter
Pa A06
,
after which manually reset;
Inactive during timer
Pa A03
following pump on.
E42
Outside Air
Sensor fault
All loads will be shut down;
Input shorted or open circuit or probe limits are exceeded (-50°C.. 100°C).
E43
Anti-freeze
external circuit
1,2
Fans and
compressors
will be shut down;
Active if analogue probe ST6 and/or ST3 (refer to
analogue inputs
) is configured as
external anti-freeze probe (
Pa H13
= 4,
Pa H16
=4);
Triggered when probe ST3 and/or ST6 detects a value below
Pa A11
;
Turns off when probe ST3 and/or ST6 detects a value above
Pa A11
+
Pa A12
;
Automatically
reset
until
alarm events per hour
reaches value of parameter
Pa A13
,
after which manually
reset
;
Inactive during timer
Pa A10
after turning on Energy 400 using On-OFF key (refer to
keyboard
) or digital input ON-OFF (refer to
digital inputs
) or start of
heating
mode.
E44
Machine out of
coolant
In all working modes, except if the boiler is active and during
defrost
, the machine is
checked to identify circuit failures. For example: gas flooding, broken inversion valve in
heat pump machines, compressor power phases exchange.
The regulator is active if
Pa A23
=1 and ST2 is configured as water output probe. An
alarm arises if one of the following conditions lasts for a minimum time of
Pa A22
:
ST2-ST1(or ST3)<
Pa A20
in heat pump configuration,
ST1(or ST3)-ST2<
Pa A20
in
cooling
configuration.
The gas flooding alarm always needs a
manual reset
.
Time count resets with each mode change or if all the
compressors
are off. After a
compressor start, the alarm is ignored for a time of
Pa A21
.
E45
Configuration
error
All
loads
will be shut down;
Triggered if at least one of the following conditions apply:
H11= 2 (ST1 configured as request for
heating
), H12= 2 (ST2 configured as request for
cooling
) and both inputs are active.
Sum of
compressors
and capacity steps on machine exceeds 4
The
keyboard
is declared present (Pa H69=1) and there is no communication between
the
keyboard
and the basic unit.
E46
High
temperature
regulation
algorithm
All
loads
will be shut down except the pump;
Triggered if probe ST1 (refer to
analogue inputs
) has a value exceeding
Pa A25
for an
amount of time exceeding Pa 26 in
cooling
mode;
Goes off if probe ST1 (refer to
analogue inputs
) has a value lower than
Pa A25
–
Pa
A12
;
Automatically
