Lennox 75M31 LIMIT CONTROL LIMIT CONTROL

LIMIT CONTROL

The Limit Control Limit Control is a programmable, fully integrated system for single-family gas and oil applications. It converts conventional outdoor temperature to a limit control signal which is used to automatically control the furnace blower and present either an on-limit or off-limit signal to the indoor thermostat.

The Limit Control is an energy management system that keeps your air conditioning operating at peak efficiency, while delivering savings of up to 35% on your monthly utility bills. Energy savings are achieved by using Outside Air and adjusting the airflow over time as outside temperatures change.
