The level electrodes in the
steam tank are short-circuited
During
operation
Operation is interrupted and error
code clearing takes place
immediately.
About 5 seconds of continuous failure is required to
trigger an error code. Check that the electrode pins
are touching the electrode tube or alternatively the
cables. Error code may be triggered by water with a
high concentration of salt or minerals that increases
electrical conduction and makes the circuit board
believe that the electrodes are short-circuited. In that
case clean/descale the water tank and the electrode
pins.
At off
Error code clearing takes place
immediately.
5
The steam tank overfull level
electrodes are not working.
During
operation
Operation is interrupted and error
code clearing takes place
immediately.
The uppermost, high (H) electrode has not detected
the water level within the preset time, refer to the
filling time in the configuration menu. Insufficient
water flow? Is the incoming water switched on? Is
there a gap in the electrode wire connections
GND/high? Grease on the coating surface of the
electrode pins? If there is no fault present at the
water connection, the value for the water level can
be checked in the configuration menu status during
restarting, to check that the level has changed from
low to mid/high during filling. If the level has not
changed at all from low, both the mid and high (M,
H) pins are faulty. If the level has only changed to
mid, it is only the high pin (H) that is faulty
At off
The error code cannot be triggered
when off, operation must be started
for the incoming water feed to open.
6
Contact lost with the heater
network control panel node.
During
operation
Operation is interrupted and
restarting takes place. For steam
production, emptying takes place
immediately after restarting is
completed in case there is water in
the tank.
Poor wiring connection? Check by removing and
refitting the RJ10 connector. Check that one of the
pins in the female RJ10 connector on the circuit
board or control panel may have become misaligned
or displaced, so that contact with the connected
RJ10 cable has been lost.
At off
Reboot. For steam production,
emptying takes place immediately
after rebooting is completed in case
there is water in the tank.
8
The steam tank has
overheated
During
operation
Operation is interrupted and error
code clearing takes place
immediately.
The sensor at the NTC input has detected
excessively high temperature in the water tank.
Check the steam pipe along its length, and its
dimensions. Check that the NTC is intact.
Resistance measurement should show approx.
10
kΩ at 25˚C and approx. 677Ω
at 100˚C
. Also
check the water quality and that automatic emptying
is activated, so that the level electrodes are not
misleading the system due to foam in the tank so
that they believe that sufficient water is available.
At off
Cannot be triggered when the
system is off.
10
Contact with the add-on board
has been lost.
During
operation
Operation interrupted. In a Tylarium
emptying of the steam secondary is
taking place 1 hour after the fault
occurred.
Try restarting the system. Check by removing and
refitting the RJ10 connector. Check that one of the
pins in the female RJ10 connector on the circuit
board may have become misaligned or displaced, so
that contact with the connected RJ10 cable has
been lost. Check the screw terminal connections on
the sensor circuit board. Alternatively change the
temperature/humidity sensor that is connected to the
RS485 input.
At off
Only the error code is shown. In a
Tylarium emptying of the steam
secondary is not taking place.
11
There is a fault in the
emptying of water from the
steam tank. Switch off the
power and perform servicing.
During
operation
Fault detected during the actual
emptying sequence of the system.
Error code clearing, Automatic
emptying, Voltage connection to the
system and water in the tank and
emptying after session completed.
Water level in the tank has been at least mid-level
when checking the tank is empty, carried out at all
emptying cycles. It must always be at its low level.
Check, is the water tank drain blocked? Is the
emptying valve operating and opening? Is the relay
on the relay board that controls the emptying valve
closing? The fault may also be caused by the high
electrode pin sensing the value as water at the same
time as the mid not sensing water, the same as the
error code (level electrodes not working, mid failure)
thereby sending unknown water level.
At off
Fault detected during the actual
emptying sequence of the system.
Error code clearing, Automatic
emptying, Voltage connection to the
system and water in the tank and
emptying after session completed.
12
Steam tank level electrodes
are not working, mid failure.
During
operation
Operation is interrupted and error
code clearing takes place
immediately.
Requires a continuous failure of the mid electrode
pin for 5 seconds at the same time as the high
electrode pin having a value equivalent to water,
before error code will be triggered. Check the
connections between the relay board and the mid
electrode. Check if the mid electrode pins are coated
with grease. The level high electrode pins may
perhaps be in contact with GND although not a
complete short-circuit but just enough so that the
value is misinterpreted as water?
At off
Error code clearing takes place
immediately.
