    I read the whole manual and there is no section on how to unlock this thermostat. If anyone knows how to unlock a Honeywell T7300B1003 thermostat, please let me know. Thanks.

There is a dip switch inside for unlocking the keyboard. As far as getting into the setup mode, it takes pressing 3 or 4 keys simultaneously. The up and down arrows are involved, but I'm not sure about the other keys.

Tip

Understanding the display on the programmable Theremostat & the 24 volt control.


Hi, I have seen this over and over, some people asking about the display on there thermostat, and getting a reply that is not at all true. This goes for all Air Conditioning and Heating systems using the programmable thermostat. I would like you to keep this in mind.Every unit has a control transformer that supplies 24 volts to there thermostat. What I am seeing a lot of is, they are told that some units are controlled by the batteries in the thermostat. No, as the unit will not function properly if the batteries are weak or dead yes, but the batteries are used for the digital display that tells the unit when to come on and what comfort zone you want. If you loose the display on a residential A/C or Heater thermostat, change out the batteries to get it back, but keep in mind that you must also have 24 volts from the control transformer for you're system to operate. To sum it all up is, the batteries are for the program only, and do not control you're unit alone. So, if you hear someone tell you that some units run on batteries and some do not, that is false as it requires both a transformer and batteries on the programmable thermostat.Thank you and Sincerely,
Shastalaker7
PS Once in a while, you will find a programmable stat that has no batteries and will use the 24 volts from transformer only. These stats are normally used on 10 ton to 75 ton commercial units, and require no batteries. For example the Honeywell T7300 stat with a non switching QE-1003 Sub-base for commercial use.If you do have a programmable stat and you are having a problem with it going through batteries very fast, and you have an extra wire in the sheathed cable like a blue one and a C terminal not being used and the same at your furnace where the T-stat wires connect, a C terminal, take and wire that blue wire to both C terminals. This will take care of this problem.
