A space temperature sensor is not reading correctly on a MicroSmart controller (Model # MSC-P-1504). What are the values for the SCALE, OFSET, and CVTYP elements?

Issue

A space temperature sensor is not reading correctly on a MicroSmart controller (Model # MSC-P-1504).  The type of sensor is not known due to its remote location.  What are the possible values for the SCALE, OFSET, and CVTYP elements?

Product Line

TAC I/A Series

Environment

MicroSmart MSC-P-1500 line of controllers

Cause

Trying to determine the type of sensor installed so a spare sensor can be brought for the service call.

Resolution

The different combinations of SCALE, OFSET, and CVTYP can narrow down the type of sensor installed (i.e. RTD, voltage, or current).  The exact model cannot be identified remotely. 

See page Table 6 on page 17 of the Installation Guide for this controller family.
