Description
Specially designed for retro control of HVAC systems, the EST4HVAC is the ideal wireless solution where mains cabling is difficult or impractical. It is mains-powered and easily interfaces to various control devices that have mains signal outputs.
With four inputs, this product is designed to work with EasySwitch single-circuit (ESR.1) or four-circuit (ESR.4) receivers to allow remote switching of up to four electrical circuits within one building or between two buildings. The wireless transmission range is up to 100m line of sight.
Each time a mains signal is applied or removed from the transmitter, it will repeatedly send this command message to the receiver over a period of time to ensure that the message is received. There is no limit to the number of receivers that can be made to work with the transmitter which means that one command could be sent to and received in two different buildings or places, making the receiver both cost-effective and versatile.
