Honeywell Sundial RF2 Wireless Cylinder (Pack 3) Y9420S2005

This wireless heating control pack is designed for managing domestic hot water and room temperature in residential installations. It includes a DT92E wireless room thermostat and a CS92A wireless cylinder thermostat, allowing for flexible placement without the need for complex wiring.
