thermostat 2:
TEV-1 is a double thermostat designated for system of protection of roof watershoots
against freezing. The device is placed in a waterproof box (IP65), sensor with double
insulation, which is a part of the device, senses ambientrature. The device operates
as zonal thermostata with independent setting of upper and bottom operational
temperature. In case the ambient temperature is higher than T1 (upper temperature),
thermostat switches heating of watershoots off (icing melts down). In case the ambient
temperature is lower than T2 (bottom temperature),thermostat also switches heating off
(to big freezing heating cannot manage to melt the ice).

Warning
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
qualification which has read and understood this instruction manual and product
functions. 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 necessary 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 electromagnetic disturbances. By correct installation, ensure good air circulation
so the maximal 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.
