Hydronic Controls

ECR offers the most advanced and complete line of switching relays, zone controls and multiple boiler system controls. The Argo brand of Hydro-Air Controls provide the easiest way to interface between the thermostat and air handler. These dependable control relays will control from 1 to 20 zones of heating/cooling and provide priority switching for domestic hot water. Boiler and A/C condenser wiring is virtually fool proof.
