Resideo HPSR103 3-Zone Switching Relay

The Resideo HPSR103 is a 3-zone Switching Relay that is specifically meant to be used in the effective management of hydronic heating systems especially in homes with central boiler. This relay enables the fine tuning of temperature and energy conservation related to the control of several heating zones. It is a 60 Hz machine that uses single-phase 120 VAC at a voltage and provides high durability and reliability of operation. This is because it has a compact design with a height of 8.75 inches, width of 2.13 inches and length of 11.75 inches thus making it easy to install and blend in several arrangements. This relay functions by initially picking signals from thermostats located in different zones; it later switches on the right zone valve or circulator to distribute heat.
