This advanced time clock allows you to set up to 16 on/off cycles per day, helping you automate ventilation schedules with accuracy and ease. Easy Setup with Flexible Scheduling The TC7D-W supports a wide range of programming options. Choose from individual days or pre-set day groupings like Monday–Friday, Monday–Sunday, or Saturday/Sunday. You can program up to 16 on/off cycles, making it perfect for facilities that require flexible ventilation schedules. A manual override switch lets you select ON, AUTO, or OFF modes at any time. The large digital interface includes dedicated buttons for DAY, HOUR, MIN, and CLOCK, along with a reset button to quickly clear all settings. You can easily scroll through and adjust cycles using the intuitive TIMER key.
