Review: DROK Electronic Thermostat Controller - Work perfectly for what I needed. wiring and programming is a little confusing, but some reviews helped with that. I have one hooked up with 24 VDC to run fan when temperature rises to high and the other one in a differnt box to do the same but 12 VDC. The temperature probes are within less than .5 degree celsius of actural temperature. Setting up for cooling: 1. Set letter to 'C' 2. Set bottom number to degrees celsius where you want the fan to turn 'OFF' 3. Set top number to degees celsius in incriments above the fan off set previously. (Example: Bottom number set to 35 and top number set to 2.5 = Fan on at 37.5 and fan off at 35) Wiring for Cooling: 1. Plus Terminal - Connect to Possitive on Battery and Positive on Fan 2. Negative Terminal - Connect to the Negative on the Battery. 3. Relay Terminal - Connect to the Negative Terminal wire. 4. Relay Terminal - Connect to the Negative on the Fan.
Review: Great little temperature controller! - Quality seems to be good, and it's easy to configure. Wish it could switch to fahrenheit, but it's not a big deal because you set it and forget it. When you cut power to the controller it retains the settings. We're using it to control a small ventilation fan for the electrical compartment in our camper, and it's been working flawlessly! Small size, great value!

## Questions & Answers

**Q: Does serial interface control work? a message "fail" is received as response to any symbol sent to the controller.**
A: I have not tried this.  I don't know the protocol, there are several that could be used.

**Q: Is the micro USB port for power only?**
A: You can also use it to send commands to the unit and read values.

**Q: How to enable the emergency stop function in cooling mode? if i enable ala setting, the board alerts as expected but the relay stays open.**
A: You need a clip on aqua stat the opens below 40° f and connect it in series with the yellow wire on the air handler. The freeze protection terminal are to protect hydronic heating coils.

**Q: Hi. Wire sensor probe is included in the packaging? Thanks**
A: Wire sensor included

### ⭐⭐⭐⭐ Accurate, straight forward operation
*by M***. on October 1, 2024*

It works as expected. I like the ease of parameter changing and its accuracy. I drive a small 12V fan for cooling my router, so far no problem. I’d rather keep high voltages and/or currents off this board. Utilize an external relay (with appropriate suppression circuitry) for more demanding loads.
