Function
Each thermostat has its own temperature sensor, coarse and fi ne temperature setting,
hysteresis setting and its output relay.
The set temperature is set as the sum of the selected temperature range and fi ne temperature
setting.
Example: Required temperature ....... + 25 °C (77 °F)
Set range ............................... + 20 °C (68 °F)
Fine setting ............................. + 5 °C (41 °F)
The device monitors the failure status of each sensor (short circuit or interruption) - if the
sensor fails, the yellow LED is lit and the corresponding red LED fl ashes. The relevant relay is
disconnected when it fails.
The device can also be operated as a single thermostat (single sensor). In this case, a 10 kΩ
resistor (part of the product package) must be connected to the unused input.

The thermostats are connected „in series" - i.e. the thermostat 1 is blocked by thermostat
2. This can be used, for example, when thermostat 1 is operational and the thermostat 2 is
blocked (emergency - for example, when overheating the device).
Warning
Device is constructed for connection for 1-phase main or DC circuits (according to
types, it is necessary to observe voltage ranges) and must be installed in accordance
with regulations and standards applicable in a country of use. Connection according
to the details in this direction. Installation, connection, setting and servicing should
be installed by qualifi ed electrician staff only, who learn this instruction and functions
of device. For right device protection should be fronted-end certain element. Before
starting installation must be main switch in position "SWITCH OFF" and device should
be out of voltage. Don´t install device to suppliers surcharge electro-magnetic
interference. By right installation of device is provide good air circulate to don´t pass
maximal operating temperature,in case of higher ambient temperature and permanent
working. For installation and setting use screw-driver cca 0.1˝ (2 mm). The device is full-
electronic - installation should be eff ected according to this. Function without problems
is too dependent on previous type of transportation, storing and manipulation. In case
of any vestige of destruction, deformation, non-function or missing part, don´t install
and made claim to seller. Product may be, after passing operating time, disassemled,
recycled or puted on protected tip.
