The new temperature monitor (new TM) has mechanical and functional differences in relation to its predecessor (TM1). In the mechanical aspect, the new TM has a reworked design, with reduced dimensions and a different terminal addressing from TM1. From a functional point of view, the new TM offers new display screens, performs additional variable readings (such as current and temperature of windings 2 and 3) and has a tree of parameters distinct from TM1. The guide provides instructions on how to perform the installation and parameterization of the new TM to replace TM1.

Parameterization sheet
To begin the replacement of the TM1 for the TM, it is necessary to record all values added to TM1 parameters before deactivating it. The following link provides a TM1 parameterization sheet to easen the organization of the values to be recorded:

After recording all parameter values, proceed with the removal of TM1 for replacement.
Installation
During the removal of the TM1, disconnect the cables from the TM1 terminals and connect them to the corresponding terminals on the TM, as shown in Table 1. Below are also the connection diagrams for TM1 and TM (Figures 2 and 3).

Parameterization
After completing the installation of the TM, proceed with the parameterization. Have the recorded parameter values of the TM1 on hand, as explained in the "Parameterization Sheet" step. Following the guidelines described in the parameter map, enter the parameters with the recorded values.
