Review: Works for HVAC Fan - Our church uses a Nest thermostat for the assembly area and there is no way for me to program it to have fans run for 4 hours every Sunday without also running fans on other days. I installed this into a plastic double-gang box below thermostat and ran wires from thermostat to this timer. Now this timer just cycles fan signal circuit when I schedule the timer. Has been working great for a couple months and everyone is comfortable.
Review: programing is pretty easy - I haven't had this timer out in the arizona sun for too long I'll let you know by editing this review. I got the timer pretty quickly and read the directions. OH OH........ Definitely Chinese made with a second rate interpreter. BUT...... the programing using what you can of the instructions is pretty easy. So far I am very pleased.

## Questions & Answers

**Q: I have one allready, it work fine but I need the pdf link to the user manual**
A: Yep

**Q: Does the connection alternate between 3 to 4 and 3 to 5?  So normally 3 to 4 and then when "on", that connection is interrupted & 3 is connected to 5?**
A: Jeff
4 is where the power goes in. 3 & 5 is where the power goes out. With timer off 4 will send power to 3 known as N/C (normally closed light switch on.) With time set at the on time the 4 will moves to 5 sending power out that terminal known as N/O normally open (light switch on.) Hope this helped.

**Q: Will the battery charge on 24 dc input power?**
A: Yes. Thanks for your question.

**Q: How does it take for the internal battery to charge?  after 24 hours on 24vac i can't get any display for programming.**
A: When you use the timer switch for the first time, input AC and charge the inbuilt battery please, then press reset button.

The timer switch is at 24-hour mode as default. Press and hold "time" button(bottom left, next to "reset") for 5 seconds till it display "AM" to set to 12-hour mode. Press and hold again "time" button for 5 seconds to set back to 24-hour mode.
It has a built-in 1.2V/40mA rechargeable battery and a industrial grade chip, so the unit retains the programming setting even in a power outage.

### ⭐ Defective relay
*by C***Y on June 5, 2023*

Buttons hardly work you must press them 20 times before it might respond. The NO contacts on the relay never have continuity even when the relay is engaged. So it's pretty much useless for my needs.
