Siemens seh 62.1U timeclock
Digital time clock used to switch an HVAC system on and off, or for the control of setback periods at night and weekends.
Integrated countdown timer for after-programmed-hours operation.
Countdown timer only option (For program override with momentary contact).
Suitable for mounting on DIN rails.
Simple programming with large, clear LCD.
Quick Daylight Savings time (DS) adjustment, (+) or (-) one hour.
Power reserve of 72 hours (super capacitor).
The microprocessor automatically stores the programmed times in chronological order. The time clock operates in one of four modes:
Adjustable Countdown Timer On
Automatically via the time program
A momentary contact close switch across M and D1 activates the Countdown Timer. The power supply is buffered by a memory back-up capacitor. In the event of a power failure, the clock will continue to run, with the program retained, for 72 hours. However, the output will go to (or remain in) the normal position.
