Programmable Digital Countdown Timer Control Relay Timer Cycle Control Module
1. Application: For controlling the smooth running of radiotube, water pump, electrical machinery, strip lights, etc.

2. Overview: This's a programmable digital countdown timer, ranging 0.1s - 999h. You can set 2 groups of for T1 and T2. With this timer, you can achieve following effect,
a. You can let your instrument start to work or stop working after a specific for . Choose T1 / T2 =0.
b. You can let your instrument work intervally. That's let it work for some for , then stop for another for , then start to work again...
c. You can choose your instrument stop working for some for , then start to work for another for . After that, it'll stop and never start to work again.

3. Function list:
P1--1: The relay switch on, after a delay of T1 for .
P1--2: The relay switch off, after a delay of T1 for .
P1--3: After a delay of T1 for , the relay switches on; then, the relay switches off after a delay of T2 for . Done.
P1--4: After a delay of T1 for , the relay switches off; then, the relay switches on after a delay of T2 for . Done.
P1--5: After a delay of T1 for , the relay switches on; then, the relay switches off after a delay of T2 for . will be repeated.
P1--6: After a delay of T1 for , the relay switches off; then, the relay switches on after a delay of T2 for . will be repeated.

4. Operation instructions:
