A1D1 CSA1 Delay Timer is known as delay-on-operate timers, and it is frequently used for blower motors to postpone the operation after a gas, electric, or oil heater has been turned on for a predetermined amount of time. Multiple compressors or motors that are turned on by the main switch can have their beginning times spaced out using on-delay timers. We pack this product in a sturdy carton box, which prevents it from damage while transporting.
