Question about Star Enerco Heat HSU45 Garage Heater 45000 BTU

2 Answers

Gas heater thermostat installation.

I installed the whole unit and now I realized it has no thermostat. I plugged it in but all I hear is a click and a green light flashes on the mother board. How do we install a thermostat to a gas heater (HSU45 garage)? Where do I connect the wires. Do I need a thermostat with 2 or 4 wires? I noticed the unit has 4 screws on the mother board, do the wires go there and if yes in which order?
Sorry for the stupid question and thank you in advance for your help.

YOU CAN CONNECT A THERMOSTAT TO THE HEATER. FIRST DO YOU STILL HAVE THE MANUEL TO THE HEATER ? THE WIRING DIAGRAM SHOULD BE IN IT. USALLY ITS ONLY A TWO WIRE HOOK UP UNLESS IT HAS A JUST FAN CONNECTION ALSO,THAN ITS A THREE WIRE HOOK UP.IT SHOULD HAVE A BUSSBAR ON THE OUT SIDE OR THE INSIDE FOR THE 24VOLT THERMOSTAT HOOK UP.

Mitsubishi ws48515 when plugged in hear a click and the green light starts blinking and set does nothing


This is a common problem with this unit.
1. Un plug the unit.
2. Take the back off of the unit
3. On the far left side you will see metal box standing up. Inside the box is your DM board. Remove the box from the unit.
4. Remove the DM board from the box.
5. Inspect these Capacitors to see if they are bulging or defective.

C81A2, C81A3, C81B3 and C81B4. The Value of these capacitors are 1000MF/16V

6. If any of these capacitors are defective, replace them all with capacitors at this rating. 680MF/16V
7. Make sure that when you replace the capacitors that you have the correct polarity. The - side of the capacitor goes toward the markings on the board.
8. Reinstall all parts of unit.
9. Plug in unit
10. Wait the 90 seconds or so that it takes for the DM to boot up ( Green Flashing Light )
11. Once Unit stops flashing you should be able to turn it on and enjoy.

Good luck to you.

The green light on my prince lionheart warmer won't stop blinking


I realize the original question is 2 1/2 years old but for future answer searchers... the flashing light means your power cord is no longer working.

Danfoss rx1 thermostat shows 'of' ?


Remove batteries from room stat,turn off the electrical supply to reciever unit.
Turn back on the electric to reciever unit,the red light should be on,press the top "manual" button,the green light should come on and boiler should fire (assuming the programmer is in an "on" period)
Press the bottom button,and keep it pressed,then press the top button until the green light flashes,stand about 6 feet away,and refit the batteries to the stat while observing the reciever unit,either the red or green light (cant remember which) should flash to show the 2 units are syncronised.

Another basic test if all seems ok,when turning the stat up or down,when the green light on the reciever unit comes on or goes off,its usually accompanied by an audible "click" ive found,that if this is not happening, the reciever unit does not switch either on or off,may be intermittant.
Replacement is the only cure.

Just installed big maxx mu75lp. When call for heat is sent, it just sits there. Fan does not run, doesnt try to lite, just get a green led blinking at about once per second. Good electrical connection,...


Make sure you are getting 24 volts back from thermostat and you are getting good connections. If you have 2 wires running to stat, connect them together at unit and see if unit starts. Check for wires unplugged, but I think that a flashing green light means you have 120 volts supply and the stat is not calling for heat

Green light flashing on back of unit near power cord also green light flashing on motherboard near power supply plug in.


I would suggest trying to replace the power supply. If that does not fix the issue, i would need to hear more about the computer.

Pover up trouble


sounds like something is drawing down on your 12 volt supply drives or on board regulators. Try it without the drives connectged, and see if you can get the system to boot up(you'll just get a notice that your drives are unavailable, but you'll already know that, right?

The green light indicates the unit thinks it is out of water. Take of rewervoir; make sure the inlets are not plugged. Open the little plug on side, clean tank w/ clear water only, and shake out all water completely. Put it all back together, but leave reservoir off. Turn on and run unit "dry". Your should hear a "flutter" sound as the unit trys to pump water from missing reservoir, the heater/steamer should be sizzling hot & pressurizing. THEN the green light if ome ON, asking you to switch it off, refill & install the water reservoir. If things don't happen in that sequence, you should be able to determine what is wrong.

Charging Black and Decker Simple Start


okay people... this is a long one, but I just did it for two units that were having this problem and it worked both times.
The problem is the unit sat on the shelf and doesn't have enough power to operate its charging cycle.
Take an extension cord and plug in the outlet charger while you also plug it into your cigarette lighter... now attempt to charge it (you will hear the familiar alarm). Now, turn on the LED light... after a short time, turn off the light and the unit will begin to charge regularly. You can then use one of the chargers to finish the job.
By doing this you are providing plenty of power to the battery while the light drains it at a slower rate... kinda forcing the battery to condition/cycle; it's just allowing the battery to take the charge. Hope this helps.
