T8490 Digital Room Thermostat with Humidity Control

Download Specs
The T8490 digital room thermostat serves a variety of commercial and residential HVAC applications; including packaged and split systems, gas and electric forced air systems, heat pumps and radiant heat. This flexible, multi-use thermostat supports up to four heating and two cooling stages. It can be independently programmed for each day (7-Day), for weekdays plus Saturday and Sunday (5/1/1), or for the same schedule every day (1-Day). It can also operate with no programmed schedule. The thermostat establishes separate setpoints for heating and cooling. Administrative settings can limit these setpoints to prudent minimum and maximum levels to ensure energy policy compliance.
