PROBLEM POSSIBLE CAUSES HOW TO PROCEED
Failure in
electronic
board
Power supply failure
Check the power supply.
Check the corresponding circuit breaker.
Cable damaged or disconnected
Check the integrity of the electronic board’s
electric circuit.
Low water
temperature
Equipment is switched off Press the key ON/OFF.
Absence of power supply or damaged
cable
Check the connection of equipment to the
socket.
Check that the corresponding circuit- breaker
is connected.
Check the integrity of the cables.
Check that the electrical cable is disconnected
from the electronic.
Check electric protection (circuit-breaker
RES).
Error in the running of components
Check the presence of error on electronic
board and consult the table of errors.
Use of large amount of hot water
Set the appliance for “BOOST” mode and wait
for water heating
Low temperature programmed as the
set-point
Adjust the temperature of the set-point.
ECO mode is selected and outside
temperature quite low
Alter the equipment to “AUTO” mode to ini-
tiate automatic management of system. Alter
the equipment to “BOOST” mode for a fast
water heating
Support resistance is off
Make sure the support resistance has power
supply.
Compressor is off Switch on compressor with key “COMP”.
Return of hot water into the cold
water circuit (safety device incorrectly
installed or damaged)
Shut off the cold water supply valve to switch
off the safety device. Open a hot water tap.
Wait 10 minutes and if you get hot water, re-
place the faulty plumbing and/or proceed with
the correct positioning of the safety device.
Clean the filter of the safety device.
Water is too
hot and/
or there is
steam
Problem with the probe
Problem with the thermostat
Check error display on electronic board.
Check correct running of thermostat
Slow running
of Thermo-
dynamic
Solar System
and exces-
sive running
of support
resistance
(AUTO)
Outside air temperature is very low
The running of the equipment depends on
weather conditions.
Inlet water temperature is very low
The running of the equipment depends on the
inlet water temperature.
Low value for Set-point Increase the value of Set-point.
Installation has low electric voltage
Make sure the installation is supplied with the
indicated value for voltage.
Problems with the thermodynamic solar
system
Check the error display in the electronic board.
Low hot wa-
ter flow rate
Loss or clogging of hydraulic circuit Check the condition of the hydraulic circuit.
Loss of water
through safe-
ty device
Absence or incorrect dimensioning of
expansion tank (if leak is not continu-
ous)
Installation and/or correct dimensioning of ex-
pansion tank.
Pressure in circuit is high (if the
leak is continuous)
Check the throttle valve (if there is one in-
stalled).
Installation of a throttle valve (if it lacks one)
