Carrier 30RAP015 Alarm T094
I have problems with a cooler 30RAP01555DA
Running almost over a year properly weekend T094 manual alarm fault not the fault display indicates discharge temperature (DTT) sensor this unit does not have that sensor also fails reviewing the A151 settings is as before
As you can determine if the card or card set ??
Any comment helps me
What is the question. card set? Can you take a screen shot of the configuration tables and service configuration
The question is how the card can detect that the sensor is failing if it does not have that sensor is programming but can not find where to configure

No as uploading an excel spreadsheet
As comp A1TY=Yes in config it must have a discharge temperature thermistor (DTT) fitted along with a Aux board as well, are you sure there is no DTT fitted.
X2 It is showing one on the wiring diagram.
It is a factory install Digital Comp with DTT along with the Aux board. DTT is wired to Aux board terminal J6 CH 11
the unit operating correctly in the diagram is in AUX J6 card but has
Reconfigure another card? some other pasword ?? the pasword york have several factory parameters
Are you saying there is no thermistor on J6.
this is no
termistor ,LVWT,EWT OAT,TEMP GAS RETURN only
You can configure a card with another refrigerant ??
Unit R410 trouble but I have another card for R-22
A1.TY- needs to be set for NO to tell the unit it's not a digital scroll which utilizes the DTT.
Morning DD Hope all is well
Makes you wonder how it has run ok for a year having configured A1TY as YES especially as he had a A151 alarm as well so if no digital comp then yes A1TY = NO and the Aux board is only doing output for MM.
Wonder who altered the config ?
Maybe he has a new MBB that was recently replaced. Maybe someone was playing in the configuration menu when they should not have.
Maybe a complete model number would tell us if the unit actually has a digital compressor ?
