I have a Battery is UB1250 12VDC 5Ah and connect to Fan that is 12DC 3.90A, Does your item does the same application as Rheostat? if this is Not the right One? which one you recommend please I look forward to your reply.

I am not an expert by any means, with regard to the application you describe above, however ;my experience with this PWM, while hooked up to a heavy duty 12 Volt car battery and a Hydrogen producing cell block; performs the VERY same as a Rheostat normally would. I have yet to hook it up to anything below12v(such as the 3.90 A 12 volt power source you mention) and see what results I can get.

the positive of course is the power I hooked mine to the positive battery cable then to the fuse out of the fuse to the thermostat depends on rotation of the fan that you want suck or blow mine blows out the front of the car one wire goes to ground depends on direction before putting connectors on try it first I do not have a switch in the car to power it. like I said I just hooked to the battery and let it work automatic. the ground wire comes from the fan not the wire from thermostat that is a switch like you have in your house on or off then adjust for temp. hard to explain if I could draw it it would be easier to explain. POWER-----------FUSE---------THERMOSTAT--------FAN CHECK ROTATION -----HOOKUP GROUNF LEAD ON FAN MOTOR

I use this relay on a 12VAC circuit. Works great. I think there is a small diode in series with the coil , so the coil would be DC. Check the one you have it might be the same.

OK, first this is a thermostat, it closes relays when the temperature is right and also the fan relay. The battery only powers the display and relay when you hit temperature. Don't worry about the voltage 12, 24. the thermostat connects the + from either the air or heater to the heater wire or the ac wire or the fan. If you go to modmyrv.com they have instructions there are only a few AC and heaters they use. Sorry for the long answer but I'm an HVAC guy, and this is not rocket science.

Good Question,I would suggest that you contact the Granite Digital Tec Line, at 510-471-6442 or their 888-819-2190 number, for a recommendation.They are very good to work with. Sorry I couldn't give you a better answer. Keep in mind that it works best as a battery maintainer.

I'm afraid I don't understand your question. I used this as a cooling fan for a ham radio by simply connecting it to a 12VDC power source.

Yeah I had that in my fan info too. But the info with this control says not to use it with a solid state fan. Who even knows what these "solid state" things are. You should be fine.

I also bought this . It only works on a 24 volt dc system. Mine was not advertised to convert from a 12 volt dc source.

yes, It is working fine for me. tun the power off before connecting. suitable for small pumps for house circulating pumps. I hope this helped.

I would probably try their control before a generic rheostat.From what I've read they can induce hum, and possibly shorten the life of the fan. That said, I use a variac auto-transformer for my fan. I already had the variac, which I use for electronic repair. It works very well, infinitely adjustable, and is very quiet!This fan seems to be very good quality, and I am quite pleased with it.

I had 48v electric hub motor sent to my brother. Instructions were vague, and wiring appeared flimsy and light duty. Another problem is need for experts to give guidance. Also, we got 2 12 volt batteries. Heavy. Sent back, not satisfied. Note need 48v. How many batteries would that be.? Really wanted it to work, but could not gamble with 2 more batteries. Do you hook up in series or parallel?

Just to clarify- a rheostat is a high power variable resistor- no electronic components- this is a solid- state device that works very well, but cannot be used for induction motors.

Does you fan work at all? Because if not then it is a fuse or the motor itself. This needs to be replaced when the fan only works on High and no other speeds. Typically, at least from my past experiences.

Hi Chas,Sorry for the delay, I could not log in to Amazon for weeks.The blower works with any DC12V source capable to provided the amperage required to drive the motor.I would however not connect it to the battery directly because of the power consumption of the motor, that may drain your battery if you forget to switch it off.Therefore my recommendation is to connect the blower to a switched and fuse protected circuit that only powers up when the generator charges the battery.I hope this helps.TT2648

Need a humidistat for the &lt;50% outside part. Found these on Amazon: IMAGE 110V Digital Air Humidity Control Controller WH8040 Range 1%~99% RH HM-40 Type It requires 120 vac power Household power, and its contacts can only handle 5 amps at 120 vac. If your 120 vac fan draws less than 5 amps, you could use this. or, C.A.P. HUM1 - Humidity Controller Really nice, but expensive.

I haven't put enough of a load on it for the fan to kick on. I use it for all my electronics only at this time. I plan to buy a low amp refrigerator, it may kick on then. My Cobra has a loud fan, but is still an efficient inverter.

Most, if not all, of the thermostats you will encounter have been color coded for commonality. So yes, you should use the RWGY terminals. If it is at all possible, try to verify what those original wires are for. For example, the G wire might be for the fan. Is there anything in the manual that says the G terminal is for the fan? If so, this is the correct terminal.Good luck and enjoy saving $$ with the new timer system!(I apologize for taking so long for this response)
