Functions and use of device (SKT 4)
Using an external temperature sensor, the SKT 4 heating element controller is
designed to warm interiors, whilst its TIMER function allows the programming of
device operation times. The IR receiver enables wireless communication with an
external DT-IR programmer which gives additional functions to the controller (i.e.
24-hour timer). All of its features make SKT 4 a universal, straight-forward, user-
friendly product.

SKT 4 controller is equipped with a simple 1-digit display which shows the
temperature setting. Above, there are two icons indicating the current setting of the
device:
Icon informs the user that the current temperature is lower than the set
temperature and the device then heats in order to reach the required setting.
Icon indicates an IR connection.
If the icon remains lit continuously, it means that communication has been
established. Pulsating of the icon means that the controller is waiting for
connection to a transmitter signal. The icon
communication function has been turned off.
The design of the device (PTC heating element) protects the user from harm
(burning risk) by limiting the temperature of the radiator to 60°C automatically,
regardless of its current setting (provided that heat output of the heating element
has been correctly matched with the heat output of the radiator).
The SKT 4 controller with SPLIT heating element are two components of this device
and allow the use of all of its basic functions (see 'LOCAL MODE OPERATION')

Additionally, SKT 4 controller can cooperate with an external transmitter
(i.e. DT-IR1) which broadens the set of controller functions (see 'REMOTE MODE
OPERATION').
LOCAL MODE OPERATION (without external infra-red transmitter)
It is possible to set the temperature to one of 10 settings, from 0- 9. Settings can be
adjusted with and buttons. Setting value equal to 0 means that the device
does not heat, values from 1 to 9 refer to the radiator temperature span from 20 to
28 degrees C. Icon indicates the current heating setting.
Turning off remote communication function in the local mode
SKT 4 has been designed to work with the external infra-red transmitter. When
switched on, the icon will begin flashing, to indicate that the device is searching
for the transmitter signal. If the user does not have an IR transmitter and they wish
to use the device in the local mode only, they can turn off the pulsating
holding down the for a few seconds. The user can also return to using "remote
mode" by pressing the same button for a few seconds.
REMOTE MODE OPERATION (operating the controller with infra-red
transmitter)
In the remote mode, room temperature is measured by the external infra-red
transmitter which sends information to the controller regarding the heat output that
is required in order to maintain the temperature set on the transmitter.
SKT 4 should automatically start searching for the IR transmitter – this is indicated
by pulsating of icon. If the icon does not pulsate, this means that the remote
communication mode is off. Press and hold the
After receipt of the first correct signal from the transmitter, SKT 4 controller will
indicate that connection has been established by turning on the
displaying a horizontal line on the screen.
After that, the operation of heating output is carried out by the IR transmitter.
Every successful communication signal received by SKT 4, is indicated by single
flashing of the horizontal line on the display. The transmitter sends the command
after every setting modification (after the display fades) and repeats it every 10
minutes in order to confirm current communication. If SKT 4 controller does not
receive any correct signal within 30 minutes time, it will automatically return to the
local mode and set itself to 0 value, while indicating loss of communication via
pulsating of the icon.
