Short description
This electronic time switch is designed to switch the double tariff relay of a meter by means
of a switched neutral hardwired internally to the time switch motor neutral and an isolated
switched output which can be utilized to switch a contactor to control e.g. storage heating.
The 2 switched outputs are interlocked to work in electric opposition i.e. when one contact is
closed the other is open and vice versa.
To gain access to the setting control the terminal cover and clear perspex cover should be
removed. Care should be execised in removing and replacing the perspex cover which when
correctly positioned fits easily on the front of the time switch.
