Tuners are the features of 75F system, that are a set of predefined parameters that can be modified or changed  in order to customize and finely tune our system's functioning to cater to specific building types and specific customer needs.

These tuner variables play a vital role in controlling the algorithm steps and functioning of different profiles.

Tuners provides the users with the capability to fine tune the tuner parameters at 4 different levels.

Below is a complete list of tuners that are available for various type of conditioning that are made available as profiles in the 75F system, along with their respective aspects lie the description, default value and Min, max incremental values and the level at which it can be applied.

|List of Tuners

The following table gives the complete list of Tuners.
