Device malfunction alert
DRY Heater has built-in malfunction moni-
toring and alert functions.
Device malfunction is signalled in the fol-
lowing way: the two outer diodes shine
with constant light while the middle diode
flashes in the following manner — sever-
al flashes followed by a longer break. The
number of diode flashes indicates an error
code as described below:
a) "Running in dry conditions" (error code:
2 flashes) — electronic system identi-
fied a situation indicating too little heat-
ing liquid inside the towel rail. Check to
see if the towel rail has been properly
filled with heating medium.
b) "Overheating" (error code: 3 flashes) —
the temperature of heating liquid inside
the towel rail is too high
• If the heater heats up despite being
turned off, it is likely that the elec-
tronics have been damaged. The
heater should be returned to the
supplier/manufacturer for repair.
• If the heater is installed inside a tow-
el rail that is connected to a central
heating system with hot water in
the system, an alert does not mean
that the heater has been damaged.
The alert signals that temperature
EN
of the installation is too high. Please
ensure that temperature of the wa-
ter inside the installation does not
exceed 82° C as this could cause
damage to the heater's thermal
fuse.
c) "Temperature sensor damaged" (error
code: 4 flashes) — There is a possibility
of electronic system malfunction. The
heater will most likely need repair.
d) "Warning against possible heat escape
into the system in central heating instal-
lations" (error code: 5 flashes) — there
is a risk of a heat escape into the sys-
tem if device is operating with the cen-
tral heating system on and system wa-
ter in circulation.
Attention: when closing the central heating
installation valves, ensure that 1 valve re-
mains open. This will prevent pressure in
the towel rail from rising excessively.
The malfunction alert may be removed by
turning the heater off and on again.
In the case of a malfunction alert, turn
the heater off and wait for the towel rail
to cool down. Check the device for a pos-
sible cause (referring to the manufacturer
"problem solving" guide) and try to resolve
it. If the heater is still signalling malfunc-
tion after it is turned on again, you should
contact your supplier or, alternatively, the
product manufacturer.
