Operating Temperature : 0 to 50 °C
Differantial controller gives output to calculate temperature difference between two sensor.
Easy access to the screen to adjust the setpoint and code protected the parameter menu
for parameter settings. If temperature difference between two sensor becomes equals or more
according to adjust setpoint and hysteresis parameter,the relay output is activated, otherwise
the relay output is disabled.

It is used for accessing to the programming mode. It can be adjusted from ‘0’ to ‘999’.
If the value equals to '0',the program does not enter password entry programming menu
Freezing prevent parameter
Parameter is changed with increament
and decreament buttons
Range:0 to +95 °C
This parameter is used to avoid tank overheating , all controller disabled for safety.
Temperature output becomes active when the value falls below two degrees .If tank
temperature becomes maximum temperature,the screen starts blinking.
Range:0 to +95 °C
When the temperature of the collector decreases less than this parameter ,differantial
control is disabled and pump closed. if the temperature becomes greater 3 ° C than
this parameter, differantial control is activated again.
Not: Freeze protection and temperature parameters is not affected by this parameter
This message gives sensor error or not connected.Controller stops and can not see
sensor value. CLL led does not blink for collector sensor error.TNK led does not blink for
tank sensor error.
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.
