## 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

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great little temperature controller!
*by Z***H on December 11, 2024*

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!

### ⭐⭐⭐⭐⭐ Stores settings.
*by D***N on February 15, 2025*

Solid unit. Good visual on the LCD screen. Programming good, instructions leave a bit to imagination. Not real clear how to set the hysteresis of the on/off cycle. Light, powers up and stores settings. Handy.

### ⭐⭐⭐⭐ Works great although an instruction sheet would be nice
*by A***D on December 27, 2019*

So far the only complaint I have about this this is the utter lack of any sort of documentation on how to use it. Other than that, it has worked great for the 45 minutes I spent playing with it.After a few minutes playing with it, however, I figured out how to use it. Here's the scoop, in case this helps anyone:1. Run power to the +V/-V pins on the terminal block. I used a 12V power supply and everything worked.2. Connect the thermocouple sensor. Mine came connected so you may not have to do this.3. Connect the thing you want to control on the other two pins on the terminal block. It's just a relay aka switch, so it doesn't matter which lead you put where. That said, the unit DOES NOT SUPPLY POWER to the device you are controlling, so you have to treat this as a switch. That is, run one power lead (say, +V or "hot") to one of the switch pins on the thermostat, connect one end of your device to the other pin, and connect the other lead of your device to the other power lead (GND, -V, or "neutral")4. Power up everything. The thermostat will need to be set before it does anything. This is really easy but undocumented.a. press SET until things start blinking.b. the bottom line will say C or H, followed by a temperature. C means "cool to stay under this temperature" and H means "heat to stay above this temperature". Press SET until the C/H indicator is blinking, then UP or DOWN to change between C and H.c. press SET again so the temperature to the right of C/H is blinking. Press UP or DOWN (you can hold these down to change values rapidly) until you get the temperature you want. If you selected C, this is the temperature where the relay will OPEN i.e. stop running your fan/cooler/whatever when the sensor cools down. If you selected H, this is where your heater/whatever will turn OFF.d. press SET again until the top temperature blinks. This is the "hysteresis" temperature. Basically, this thing controls where the relay will CLOSE i.e. turn on your fan/cooler/heater whatever. KEY THING TO UNDERSTAND: the hysteresis temperature is the difference between the "ON" point and the "OFF" point. Example: if you pick C20.0 on the bottom line and 5.0 on the top line, the thermostat will operate in Cooling (C) mode. It will turn on the cooler at 25*C (77*F) and it will turn off the cooler at 20*C (68*F). It will always try to keep the temperature between 20 and 25. Another example: if you pick H10.0 on the bottom and 10.0 on the top, it will be in heating mode and will turn on your heater at 0*C (32*F) and will turn it off at 20*C (68*F). If this doesn't make sense, just remember that in cooling mode it will keep the MAX temperature below the bottom PLUS the top value, and in heating mode it will keep the MIN temperature above the bottom value MINUS the top value. The larger the top value, the larger the allowable swing in temperatures, and the longer time your heater/cooler/whatever will be operating while it is doing its thing. That said, it will also run with fewer starts/stops, so that may be good for the lifetime of the heater/cooler/whatever.
