HVAC system Wireless Transmitter
Specially designed for retro control of HVAC systems the EST4HVAC is the ideal wireless solution where mains cabling is difficult or impractical. This model is mains voltage powered and designed so that it can easily interface to various control devices that have mains signal outputs.
With four inputs this product is designed to work with the EasySwitch single circuit (ESR.1) or four circuit (ESR.4) receivers to allow remote switching of up to four electrical circuits within a building or from one building to another.
Transmission range is up to 100 metres line of sight, and will work in situations that are not line of sight, such as from one end of a house to the other, however the transmission range will be reduced.
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 than 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. This provides extreme versatility and cost saving.
