Temperature Controller
Universal Programmable
Introduction
is a specialized device, that maintains the temperature of the controlled
system, in accordance to the set temperature. It can be used both for heating and
cooling in wide temperature range.
Besides altering the set temperature, the controller also provides access to other
parameters. This flexibility makes it suitable and convenient for integrating in wide
variety of heating systems.
monitors the temperature of the controlled system and according to the
set temperature, switches the connected load on or off, which in turn heats up or
cools down the system.
Installation
is designed for DIN rail mounting, use it only indoors in dry closed places
and away from strong electromagnetic fields.
The device is powered from mains high voltage! Please follow the safety
regulations for operating under high voltage!
Included in the set
Temperature sensor :
o Sensor measuring the temperature of the controlled system
NTC (-40 .. 125С) or op ) or optionally Pt1000 (-40 .. 200С) or op )
Electrical connection
The thermostat should be powered through external mains breaker (last step of
the installation process), voltage 230 V / 50 Hz.

Connect the load to the terminal NO (normal open) of the relay R1 and to mains
neutral N. The terminal NC (normal closed) is active when the relay switches off and
can be used in some special cases.
The temperature sensor has no polarity and when installing it, the cable can be
extended up to 100 m using the following cable size: up to 50 m – 0.75 mm
100 m – 1.5 mm 2 . It's advised, that the cables of the temperature sensors and the high
voltage ones be distanced from one another at 100 mm. When using in environment
with strong electromagnetic fields, use shielded cable for low voltages, grounded in
both ends.
Maximum size of the cable to be connected to the terminals – 2.5 mm

Set Temperature
In order to check the set temperature, press any of the buttons
device switches to
of the set temperature. To change the value, use
decrease. At first the temperature is changed with the minimal step, but if you hold
the button pressed, the step is increased progressively. This way it is very convenient
to quickly alter the temperature in wide range.
Changing the set temperature immediately effects the control algorithm. This can
be used to forcefully switch the load on or off if necessary.
Pressing the button

Errors
The device automatically enters error display mode if the measured temperature
is out of the acceptable limits. In this mode the device beeps and on the display is
shown the cause for the error. If there is an electrical issue with the temperature
sensor, then instead of temperature, the following is displayed:
