It is a single thermostat for temperature monitoring with separated sensor (except for
TER-3F). Device is located in a switchboard and external sensor senses temperature of
required space, object or liquid. Supply is not galvanically separated from sensor but
sensor is double insulated. Maximal length of sensor cable is 12 m (39.4´). Temperature
sensing is decreased by set hysteresis. When installing it is necessary to keep in mind that
hysteresis is increased by temperature gradient between sensor's jacket and thermistor.
Warning
Device is constructed for connection in 1-phase AC 230 V main alternating current voltage
and must be installed according to norms valid in the state of application. Connection
according to the details in this direction. Installation, connection, setting and servicing
should be installed by qualifi ed electrician staff only, who has learnt these instruction and
functions of the device. This device contains protection against overvoltage peaks and
disturbancies in supply. For correct function of the protection of this device there must
be suitable protections of higher degree (A, B, C) installed in front of them. According
to standards elimination of disturbancies must be ensured. Before installation the main
switch must be in position "OFF" and the device should be de-energized. Don´t install the
device to sources of excessive electro-magnetic interference. By correct installation ensure
ideal air circulation so in case of permanent operation and higher ambient temperature
the maximal operating temperature of the device is not exceeded. For installation and
setting use screw-driver cca 2 mm. The device is fully-electronic - installation should be
carried out according to this fact. Non-problematic function depends also on the way of
transportation, storing and handling. In case of any signs of destruction, deformation,
non-function or missing part, don´t install and claim at your seller.
