Device malfuncon alert
DRY Heater has built-in malfuncon moni-
toring and alert funcons.
Device malfuncon is signalled in the fol-
lowing way: the two outer diodes shine with
constant light while the middle diode ash-
es in the following manner — several ash-
es followed by a longer break. The number
of diode ashes indicates an error code as
described below:
a) “Running in dry condions” (error code:
2 ashes) — electronic system iden-
ed a situaon indicang too lile heat-
ing liquid inside the towel rail. Check to
see if the towel rail has been properly
lled with heang medium.
b) “Overheang” (error code: 3 ashes) —
the temperature of heang liquid inside
the towel rail is too high
• If the heater heats up despite being
turned o, it is likely that the elec-
tronics have been damaged. The heat-
er should be returned to the suppli-
er/manufacturer for repair.
• If the heater is installed inside a tow-
el rail that is connected to a central
heang system with hot water in the
system, an alert does not mean that
the heater has been damaged. The
alert signals that temperature of the
installaon is too high. Please en-
sure that temperature of the water
inside the installaon does not ex-
ceed 82° C as this could cause dam-
age to the heater’s thermal fuse.
c) “Temperature sensor damaged” (error
code: 4 ashes) — There is a possibility
of electronic system malfuncon. The
heater will most likely need repair.
d) “Warning against possible heat escape
into the system in central heang instal-
laons” (error code: 5 ashes) — there
is a risk of a heat escape into the sys-
tem if device is operang with the cen-
tral heang system on and system wa-
ter in circulaon.
Aenon: when closing the central heang
installaon valves, ensure that 1 valve re-
mains open. This will prevent pressure in
the towel rail from rising excessively.
The malfuncon alert may be removed by
turning the heater o and on again.
In the case of a malfuncon alert, turn the
heater o and wait for the towel rail to
cool down. Check the device for a possi-
ble cause (referring to the manufacturer
“problem solving” guide) and try to resolve
it. If the heater is sll signalling malfunc-
on aer it is turned on again, you should
contact your supplier or, alternavely, the
product manufacturer.
