2.5 TROUBLESHOOTING.
The hydronic module signals any anomalies by
flashing a code on the display (14) according to
the following table.
Hydronic module error codes are preceded by
the letter "E", while error codes referring to
the condensing unit are preceded by the letter
"A". For the latter, refer to the condensing unit
booklet for the complete list of all the anomalies.
The CAR
V2
displays error codes with only the
last two digits (e.g. E184 = ERR 84).
Error
Code
Anomaly signalled Cause Hydronic module status / Solution
E 2
Safety thermostat
block (over-temper-
ature)
During normal operation, if a fault causes excessive overheating
internally, the boiler goes into overheating block.
Press the Reset button (1)
E 5 Flow probe anomaly The board detects an anomaly on the flow NTC probe. The system does not start (1).
E 12
Storage tank probe
anomaly
The board detects an anomaly on the storage tank probe
The hydronic module is unable to pro-
duce domestic hot water (1).
E 23
Return probe anomaly
The board detects an anomaly on the return NTC probe The system does not start (1).
E 24
Push button control
panel anomaly
The board detects an anomaly on the pushbutton panel.
If normal conditions are restored, the
system restarts without having to be reset
(1).
E 26
System flowmeter
anomaly
The board detects an anomaly on the system flowmeter.
Return pump (optional) always working.
The system does not start (1).
Make sure the return pump (optional) only
activates when requested.
E 27
Insufficient circulation
This happens when the hydronic module overheats due to poor water
circulation in the primary circuit. The causes can be:
- low system circulation; check that no shut-off devices are closed on
the central heating circuit and that the system is free of air (deaer-
ated);
- pump blocked; free the pump.
Press the Reset button (1).
E 31
Loss of communica-
tion with the CAR
V2
(zone 1)
This happens when an incompatible remote control is connected or
when communication between the hydronic module and CAR
V2
is lost.
Cut power to the hydronic module then
power it back on. If the Remote Control is
still not detected at restart, the system will
switch to local operating mode, i.e. using
the controls on the control panel. In this
case the “Central Heating” (1) mode cannot
be activated.
E 32
Low temperature zone 2
probe anomaly
If the board detects an anomaly on the low temperature zone 2 probe,
the system cannot work in the affected area.
(1)
E 37
Low power supply
voltage
This occurs when the power supply voltage is lower than the allowed
limits for correct system operation.
If normal conditions are restored, the sys-
tem restarts without having to be reset (1)
46
Low temperature safety
thermostat (optional)
During normal operation, if an anomaly causes excessive overheating
of the flow temperature in the low temperature zone, the unit indicates
the malfunction.
The unit does not meet the zone central
heating requirement. (1)
E 50
External probe missing
or faulty
In the event the external probe is not connected or is faulty, the
anomaly is indicated.
Check the external probe connection.
The system continues to operate with the
external probe integrated in the condensing
unit (1).
E 54
Central heating storage
tank probe anomaly
(optional)
The central heating storage tank has an out of range resistive value Puffer mode is disabled. (1)
E 129
Zone 1 humidity probe
anomaly
Anomaly on the zone 1 humidity probe (optional). Zone humidity
cannot be checked.
In addition to the humidity, the dew point
is not calculated for the zone (1) either
E 130
Zone 2 humidity probe
anomaly
Anomaly on the zone 2 humidity probe (optional). Zone humidity
cannot be checked.
In addition to the humidity, the dew point
is not calculated for the zone (1) either
E177
DHW maximum time
alarm
Domestic hot water production is not met within the pre-estab-
lished time
The system continues to operate with
non-optimal performance (1)
E178
Anti-Legionella cycle
not successful
The anti-Legionella cycle is run without success within the pre-es-
tablished time
(1)
E179
Liquid phase probe
anomaly
The board detects an anomaly on the liquid phase NTC probe. The system does not start (1).
(1) If the block or anomaly persists, contact an authorised company (e.g. Immergas Technical After-Sales Service).
