ZX1
Heating element unit heats the radiator that it is installed in. The device has
a user-friendly temperature regulation system allowing the device to work with only a
half or full of its heating output.
Button
is used to turn the device on / off.
When turned off and then back on again, the device will heat with the same heating
output as before it was turned off.
Button
is used to set the ECONOMICAL mode – this is indicated by a yellow diode
in the top left corner (the device will start operating by turning itself on and off every 7
seconds).
Button
is used to set the COMFORT mode (the device will operate with its full
output continuously) – this is indicated by a red diode in the bottom right corner.
Built-in temperature sensor protects the device from overheating, limiting the tempera-
ture of the radiator to maximum of 60°C.
Construction of the heating element unit as well as physical characteristics of the heating
agent cause that the bottom pipes (especially the two at the very bottom of the radiator)
may have a lower temperature than the remaining parts of the radiator – this is a normal
phenomenon.
PROBLEM SOLVING
Problem
Possible cause
Solution
Device is connected, no
diodes are on, heating ele-
ment does not heat.
Device is not turned on
Turn the device using
button
Connection problem
Check the connection,
plug and the socket.
Heating element does not
heat, diodes are flashing
alternately.
Device signals emergency,
temperature sensor is
damaged.
Turn the device off, wait
for the radiator to cool
down and turn it back on.
Heating element does
not heat, diodes indicate
correct operation.
Thermal fuse is burnt
or heating element is
damaged.
Turn the device off, wait
for the radiator to cool
down and turn it back on.
Heating element heats
although the device has
been turned off with the
button.
Electronics damage.
Disconnect the device
completely from the
