TechGrow Interval Timer Pro Handbuch Seite 9

1. Operation of the Interval Timer
Pro
The Interval Timer Pro switches any device on and off at
accurately determined intervals. You can choose from
different time units: sec/sec, sec/min, sec/hours,
sec/days, min/sec, min/min, min/hours, min/days,
hours/days, hours/hours, hours/min, hours/sec,
days/days, days/hours, days/min, days/sec, with an
adjustment range of 1 – 99. For instance: pause 4
hours/pulse 15 minutes. This cycles repeats itself.
The Interval Timer Pro has a built-in LDR (Light
Dependent Resistor – light sensor) and offers a choice
of three programs: day, night and 24-hour. During day
mode, the timer only works if the built-in light sensor
detects light. In this case, the light sensor automatically
switches off the Interval Timer Pro when no more light
is detected. When the light sensor detects light again,
the interval program restarts. During night mode this is
exactly the other way around. For continuous operation,
choose the 24-hour option.
The heavy relay allows you to switch devices up to 10
amperes.
2. Control and set the Interval Timer
Pro
You can complete all settings with the Push-and-Turn
Knob (from now on PTK).
During the startup of the Interval Timer Pro you will see
the following screen. The red and green LEDs flash
alternately:
