Looking to replace your discontinued Honeywell 7212 Economizer Controller? Ask us about the new, Direct Replacement, Siemens Economizer Controller (POL220).
The Economizer Controller is used with Rooftop Units and Air Handling Unit Economizer Dampers to bring in fresh air, when conditions are right, without the need for mechanical cooling, allowing the use of unconditioned outside air to cool a building. The result is “Free” cooling and energy and energy savings. The Free Cooling air determination is based on customer temperature and humidity selections, as well as optional Demand Control Ventilation (DCV) strategies with CO2 level selection. This stand alone Economizer System is perfect for new installations and retrofit installations that do not have a building automation system.
