How to Turn Off Luxpro Thermostat

Even though Luxpro Thermostats are extremely reliable and useful, occasionally you may need to turn off your Luxpro Thermostat. This includes times when you may suddenly find that the room you are in has suddenly turned freezing cold or has become exceedingly hot. Read on to see what you can do to turn off your Luxpro Thermostat.

If you want to set/reset your Lux/Luxpro Thermostat and want to know how to turn off your Luxpro Thermostat, first try to replace the batteries in the Thermostat. Then, check the circuit breakers and make sure that none of the wires are not working properly and are in perfect working order.

Check to see if your Luxpro Thermostat is showing low battery levels. If this is not the problem, check to make sure that the Thermostat is indeed receiving enough power.

If not enough power is being supplied to the Thermostat, check to see if any of the circuit breakers have tripped because of some electrical issue or because of a short circuit of some kind.

You can also check the contacts on the Subbase. They will appear as 2 brass prongs that are located on the wire terminals above the letters that are on the wire terminals.

If you are indeed having any problems with the heating and cooling functions of your thermostat, you can try to press the two contacts together in a gentle fashion so as not to cause any damage to them.

In addition, you can attempt to clean the single contact pens that are on the Circuit Board. You can try to use a pencil eraser to accomplish this.

Another possible fix to this problem is to analyze the Dip Switches which you can find on the posterior part of the Thermostat.

Be sure that Switch number one is in the On Position and that the Fan Switch is in the Electric Position.

Now, restart your Lux/Luxpro Thermostat.

Check all the connectors to make sure that they are all connected to their appropriate terminals as directed by your owner’s manual. Also, check all the wiring to be sure it is not the reason for problems with your thermostat.

Use a Multimeter to be sure that the line voltage is intact and that a voltage problem is not what is causing the problems with your Luxpro Thermostat.

Look for any sign that the keyboard is locked. If so, you should be able to see a Locked Keyboard Message.

Go ahead and tap on Unlock the Keyboard.  Then select OK and then the Up and Down arrows so you can enter your Lock Code.

When your Luxpro turns back on, it will be unlocked.

If the display appears hard to read or illegible, it may be necessary to take the plastic off of the display so that is more readable.

If the display is not easily readable, it is probably due to batteries that are running low. If you see a message reading Override, it is usually because of an irregular increase in temperature that is drastically different to the values programmed into your Luxpro Thermostat.

This reading should just simply disappear when the next temperature you have scheduled is reached.  

If you see an Error Code indicating HI or Low, it usually means that your room’s temperature has gone beyond the acceptable range for your thermostat.

You will be able to see this reading on the display screen at the time the temperature in a particular room has returned to the normal range.

Another way to attempt to turn off the Luxpro Thermostat is to restart the Thermostat. If you look under the display screen you will see a few buttons on a cover. Look for the Power Button and then press it. This will turn the Thermostat off and you can press the Power Button again to turn the unit back on again.
