When the thermostat detects an input signal error, it sends and displays this
information.
The following conditions may cause an error condition, and when an error occurs, the
LED flashes in a 0.5 second cycle.
◆
Sensor input exceeds the upper temperature range
;
◆
Sensor input is below the lower temperature range
;
◆
Sensor disconnected or not connected.
Once the error alarm is removed (sensor connected / restored to temperature range),
the device will continue to operate normally
When power is turned on, or in the standard heating/cooling mode,
HHHH is displayed when the control output is 0%, and LLLL is displayed
when the control output is 100%.
When power is turned on, or in the standard heating/cooling mode, the
heating output is 0%, the HHHH is displayed when the cooling output is
100%, the heating output is 100%, and the LLLL is displayed when the
cooling output is 0%.
Manually control the output priority order: Heating (Cooling)_MV >
Stop_MV > Sensor Error _MV
Automatic control output priority: Stop _MV > Sensor Error _MV >
Heating (Refrigeration) _MV
Sensor error MV
This function is used to control the sensor error during output, the user can set
ON/OFF, MV setting, etc.
The MV value is controlled by ON/OFF or PID and is based on the MV control value.
