6.7.5 Error
The controller diagnoses input signals for errors and displays messages accordingly. These
messages inform the user of device problems.
Message Input Description
Output
HHHH
Temperature
sensor
Flashes at 0.5 sec. intervals if the
input value is above the input
range.
Standard type:
Heating: 0%, Cooling: 100%
Heating&Cooling:
Heating: 0%, Cooling: 100%
Analog
Flashes at 0.5 sec. intervals if the
input value is over 5 to 10% of high
limit or low limit value.
Normal output
LLLL
Temperature
sensor
Flashes at 0.5 sec. intervals if the
input value is below the input
range.
Standard type:
Heating: 100%, Cooling: 0%
Heating&Cooling:
Heating: 100%, Cooling: 0%
Analog
Flashes at 0.5 sec. intervals if the
input value is over 5 to 10% of low
limit or high limit value.
Normal output
OPEN
Temperature
sensor
Flashes at 0.5 sec. intervals in the
event of an input disconnection.
Outputs the set MV at ErMV
Analog
Flashes at 0.5 sec. intervals if F.S.
is over ±10%.
ERR
Temperature
sensor
Flashes at 0.5 sec. intervals if there
is error for setting and it returns to
the error-before screen.
-
When input value returns to the input range, alarm is deactivated and it operates normally.
When in heating control mode and powered on, or standard control state, output is 0% if HHHH is
displayed and 100% if LLLL is displayed.
When in cooling control and powered on (or standard control state), output is 100% if HHHH is
displayed and 0% if LLLL is displayed.
When in heating & cooling control and powered on or standard control state, heating output is
0% and cooling output 100% if HHHH is displayed, and heating output is 100% and cooling
output 0% if LLLL is displayed.
6.7.5.1 MV Settings upon sensor break error [OPEN](MV for Error) [PAR5 → ErMV]
In the event of a sensor open error you can set control output value to predefined MV instead of
ON/OFF control or PID control.
Ignores MV by ON/OFF control or PID control, and sends out a control value based on the
defined MV.
