Heating element unit heats the radiator that it is installed in and precisely controls its
temperature at the same time. Buttons and are used to regulate temperature whilst
the icon indicates that the radiator is being preheated.
Turning the device on does not mean that it uses the same maximum power for the
whole time it is on. On turning the device on, it operates with the nominal power for
a short period of time in order to heat up the radiator to the set temperature. After
that it turns itself on and off periodically, using only as much energy as it is required
to maintain the set temperature of the radiator for current external conditions (see:
Actual working time meter
).
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.
ZX4 controller installed on the SPLIT heating element is the basic configuration of this
type of heating element unit which allows use of all the basic features of the device (see:
Local mode operation
).
ZX4 controller can also cooperate with an external wall-mounted transmitter (ie. DT-IR
type), which adds additional features to the basic set (see:
Remote mode operation
).
LOCAL MODE OPERATION (WITHOUT IR TRANSMITTER)
Heating mode
It is possible to set 5 temperature levels in the local mode. Settings are modified with
and buttons. Possible working levels are as follows: 0 (does not heat) and from 1 to 5,
each setting indicating a temperature range from 30 to 60 degrees Celsius accordingly.
icon indicates that the device is heating.
TIMER FUNCTION
button is used to turn the mode on and set the time after which the device is to be
turned off automatically.
In order to activate the Timer Function:
– Press button shortly – display panel will show timer working time of 1H (1 hour)
– Every subsequent pressing of the button will prolong timer working time (2-4
hours)
In order to deactivate the Timer Function, set the time to 0H (press the button a few
times) or turn the device off and back on.
While the Timer Function is on you can modify:
– temperature of the radiator – buttons and .
– Timer working time left – button
Actual working time meter
The unique feature measuring the actual working time of the heating element adds up
the periods during which the device was using nominal electric power (during standard
operation the device regulates the temperature and uses very little power thanks to the
fact that it turns itself off for longer periods).
It can be checked at any time how much electricity has been used, ie. during all day’s
operation. In practice it turns out to be up to a few dozens of percent less!
The number displayed on the meter reflects the actual energy consumption, therefore
you can measure the actual cost of energy used by multiplying the number on the meter
by the nominal heating output of the heating element and the price of electricity (1 kW).
