Resolution Of Problems; How To Proceed - Energie MONOBLOC 100esm Manual Tecnico

Technical Manual
Error originated by:
• Pressure switch of high pressure activat-
ed;
• Pressure switch of low pressure activated;
• Temperature probe of the evaporator
damaged;
Solution:
• Verify the integrity of the probe's connec-
id
tions on the controller;
• Verify the existence of any cooling leak;
• Temperature in the thermal accumulator
very high;
• Measure the probe's resistance (NTC
10KΩ, resistance in 25°C equals ± 10KΩ);
• Substitute probe;
• Substitute pressure switch.

9. RESOLUTION OF PROBLEMS

Problem
Failure in electronic
board
Low water tempera-
ture
or lack of hot water
Possible Causes
Power supply failure
Cable damaged or disconnect-
ed
Low temperature programmed
as the set-point
Error activation
Cable damaged or disconnect-
ed
Use of large amount of hot wa-
ter
Return of hot water into the
cold water circuit (safety de-
vice incorrectly installed or
damaged)
ECO mode selected and exter-
nal temperature really low
Electric heater OFF
MONOBLOC 100L
All the active outputs actives are
activated (compressor, resistance and
ventilator)

How to Proceed

Check the power supply.
Check the corresponding circuit breaker.
Check the integrity of the electronic board's
electric circuit.
Adjust the temperature of the set-point. 53
from factory.
Check the presence of error on electronic
board and consult the table of errors. (cap. 7)
Check the connection of equipment to the plug
Check that the corresponding circuit-breaker
is connected.
Check the integrity of the cables.
Check that the electrical cable is disconnected
from the power board.
Check electric protection (fuse).
Change the equipment to "BOOST" mode for a
fast water heating.
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.
Change the equipment to "AUTO" mode to ini-
tiate automatic management of system
Change the equipment to "BOOST" mode for a
fast water heating.
Make sure the backup electric heater has pow-
er supply.
