Programmable electronic night lowering control for heating systems has additional operating switch for day temperature raising, and additional count value of counter is stored in memory during operating of additional switch

摘要

The programmable electronic night temperature lowering control for heating systems has an operating component (1) with an operating switch (2) for night temperature lowering, an electronic counter (3) which counts in predetermined time intervals up to a maximum value, and a memory (5) to store count values in dependence upon the operation of the operating switch. The operating component has an additional operating switch (7) for day temperature raising, and an additional count value of the counter is stored in the memory during the operating of the additional switch.
