1.3 Functions of the program timer Variotime
Variotime is an electronic timer with 24 hour and/or 7 day program switching an electric appliance
on and off at programmed times.
Variotime switches an electric appliance via a relay. During a programmable period, the relay
contacts are closed, closing the electrical circuit and activating the appliance in which the timer is
installed. At the end of this period, the relay contacts open again, breaking the electrical circuit
and deactivating the appliance.
Variotime Single has one relay for switching one load (1 “channel”).
Variotime Twin has two relays for switching two loads (2 “channels”) independently, however, with
the full scope of functions for each channel.
Scope of functions:
• Time of day in 24 hour or 12 hour format (am/pm)
• 7 day program, optional 24 hour program only
• 16 switching points (8 x ON, 8 x OFF)
• Up to 112 switchings per week by forming program blocks
• Reset function
