3.2 Device Label and Connection Diagram
3.1 Supply Voltage Input Connection of the Device
Make sure that the power supply voltage is the same
indicated on the instrument.
Switch on the power supply only after that all the electrical
connections have been completed.
Supply voltage range must be determined in order. While
installing the unit, supply voltage range must be controlled
and appropriate supply voltage must be applied to the unit.
c
There is no power supply switch on the device. So a power
supply switch must be added to the supply voltage input.
Power switch must be two poled for seperating phase and
neutral, On/Off condition of power supply switch is very
important in electrical connection.
External fuse that on Vpower supply inputs must be on
phase connection.
External fuse that on Zpower supply inputs must be on (+)
connection.

BUTTON DEFINITIONS
1. Increment Button :
** It is used to increase the value in the Set screen and Programming mode.
** In main operation screen; if this button pressed SET
2. Decrement Button :
** It is used to decrease the value in the Set screen and Programming mode.
** In main operation screen; if this button pressed SET
3. Compressor Button:
** in the Set screen and Programming mode, it is used to saving parameter.
** In main operation screen, it is used to activated compressor output.
4. Fan Button:
** In main operation screen; if this button pressed Fan outputs are can be activated with
sequentialy.
** It is used to exit from Set screen and Programming mode to main operation screen without
Saving parameter.

5.1 Programming Mode Parameter List
Hysteresis Parameter for Compressor Output ( Default = 1 )
This parameter can be adjusted between 0 and %50 of device scale.
In ON/OFF control algorithm, temperature
value is tried to keep equal to set value by
opening or closing the last control element.
ON/OFF controlled system, temperature
value oscillates continuously. Temperature
value’s oscillation period or amplitude around
set value changes according to controlled
system. For reducing oscillation period of
temperature value, a threshold zone is formed
below or around set value and this zone is
named hysteresis.
