This pt4 pr. High during ti70 alarm comes only when discharging initiate( not everytime only at every 12 to 24 hrs after).And alarm doesn't go it only goes after manual discharging again.I haven't touch pr11 parameter.And during ti70 pt4 suddenly becomes high to low.My transducer is ok not received any alarm lately i.e, MT value .
Seperation temperature maintains from 93 to 99 as my i have to adjust manually controller not working.
I just lossen the air connection to v1 to decrease some air pressure and also i did increase pt4 high parameters set to 3.6.
But this alrm is not regularly coming but coming.
