Parameter
Function :
To set allowable high
temperature limit.
To change P2 parameter,
press the set key.
Use UP/DOWN key to set desired value.
Once set at a particular value, this will not
allow the set point to go above this
value and below P3 setting.
Example :
Setting this parameter at
0
50.0 C will not allow the set point to go
0
above 50.0 C also if the temperature
0
reaches 50.0 C, the display will show HT
(High Temperature). The alarm will be
ON. But at power on till the ADT delay is
over controller will not generate HT Alarm.
