Product Description

The HONEYWELL RESIDENTIAL R845A1030 switching relay provides DPST switching for hot water zone control systems, or SPST control of two separate loads. It is designed for 1 line-1 line/low voltage applications. The relay features an integral transformer that provides low voltage power for the control circuit and an enclosed intermediate DPST switching relay for 24 volt 2 wire thermostat control of one line voltage and one line or low voltage devices with a 120 volt primary power supply.

• Provides DPST switching for hot water zone control systems or SPST control of two separate loads
