6.2Switching time program enabling

The modular Smile SDC/DHC 43 series of controllers features three switching time programs for each heating circuit that can be set separately.

When supplied, only one switching time program is enabled. The use of only a single switching time program for a wide range of applications makes it possible to simplify operation.
