Trane MOD3099 Reliatel Economizer Logic Module

The Trane MOD3099 Reliatel Economizer Logic Module is a replacement part of Trane HVAC systems designed to improve the systems’ performance as well as reduce energy consumption. This module controls economizer function which some HVAC systems use to cool the building when the weather is appropriate. It works through the comparison of the outside air’s humidity and temperature to that inside. The module saves energy by drawing fresh air from outside instead of turning on the mechanical cooling system if the outside air is dry and cool enough. Designed particularly for Reliatel systems.
