Function
The device is constructed to be connected into 1-phase main and must be installed in
accordance with regulations and norms applicable in a particular country. Installation,
connection and setting can be done only by a person with an adequate electro-technical
qualifi cation which has read and understood this instruction manual and product func-
tions. The device contains protections against over-voltage peaks and disturbing elements
in the supply main. Too ensure correct function of these protection elements it is neces-
sary to front-end other protective elements of higher degree (A, B, C) and screening of
disturbances of switched devices (contactors, motors, inductive load etc.) as it is stated in
a standard. Before you start with installation, make sure that the device is not energized
and that the main switch is OFF. Do not install the device to the sources of excessive elec-
tromagnetic disturbances. By correct installation, ensure good air circulation so the maxi-
mal allowed operational temperature is not exceeded in case of permanent operation and
higher ambient temperature. While installing the device use screwdriver width approx. 2
mm. Keep in mind that this device is fully electronic while installing. Correct function of
the device is also depended on transportation, storing and handling. In case you notice
any signs of damage, deformation, malfunction or missing piece, do not install this device
and claim it at the seller. After operational life treat the product as electronic waste.

TEV-2 and TEV-3 are universal single thermostats for universal use. In case ambient
temperature is higher than set temperature relay is open (function HEATING), for cooling
function (opposite function) is possible to use NC contact of relay (V2).
