Characteristics
- two-level thermostat with function “WINDOW” meaning that output is switched in case the measured temperature is within set range (adjustable in range -20.. +20 °C / -4 °F to +68 °F)
- used as protection against freezing (water-shoots, pavements, drives, pipes, etc.) heating is on when temperature falls under set upper level (e.g. +5 °C / +41 °F) and off in case it falls under lower level (e.g. -10 °C / 14 °F, when heating is not able eff ectively operate)
- thermostat is placed in water-proof box with IP65, which allows installation outside, with in-built sensor TZ-0 (included in the supply)
- thermostat status is indicated by LED (3colours) under transparent cover
- function monitoring short-circuit and sensor disconnection (break)
- output changeover contact 16 A / SPDT (AC1)

h) hysteresis
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
Technical parameters 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 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.
