ESI ES1247B Single Channel Electronic Time Switch Programmer

The ES1247B is a single channel electronic time switch and provides volt free output contacts making it an ideal solution for use with both line voltage and low voltage control circuits. The time switch can be configured for 7 day, 5/2 day or 24 hour operation. It is an ideal solution for combi-boilers, for systems having a common Heating and Hot Water zone, and for the control of additional heating zones.

The wall plate used follows the industry standard pattern, as used by many of the other time control manufacturers. This allows for direct replacement often without the need for re-wiring.
