a) Program time switch
If an analog program time switch is
mounted it can be set for normal and
reduced temperature periods by pushing
the slides in towards the middle to set
the periods in which an reduced
temperature is required.
The correct time and day can be set
opposite the markings by turning the dial
in the direction of the arrow.
If a digital time switch type ECA 9016 or
9017 is used, see the instructions
enclosed with the time switch.
