Digital Immersion & General Purpose Timeswitch

The OP-IHTDIGI 24/7 digital immersion heater timer switch is a versatile, general purpose digital time switch designed for surface mounting, perfect for managing immersion and other standard switching applications. With 24 hour and 7 day programming options, it offers flexibility and precision in scheduling. The timer can switch on/off randomly within ±28 minutes of the set time, adding unpredictability. For example, a programmed-ON time of 8:00-9:00 may vary, with the ON event occurring between 7:32 and 8:28 and the OFF event between 8:32 and 9:28. Not suitable for discharge or LED lighting without a contactor. Ideal for both immersion heating and general purpose switching, this time switch ensures reliable and efficient control for a range of electrical systems.
