Remark:
Deadzone for floor temp.: i.e. the setting deadzone for floor sensor is 2,
OSV is 42
℃
, when actual temp. reach 44
℃
, the relay will stop working;
when actual temp. is back to 40
℃
, the relay starts working again. It works
when room temp. is lower than set temp.
Sensor error:
Please select the right sensor mode. If select the different mode or there
is error of sensor, Err will display on the LCD screen, the thermostat will
stop heating till the problem is solved.
