How can I upgrade my thermostat?  The Pro1 professional thermostat system was designed to give you the best technology of today and the flexibility for easy upgrading in the future.  Our innovative design always has the same footprint so you never have to worry about wall marks to repair if you upgrade to a new model.  Your Heating and Air Conditioning technician can help you upgrade.

Should my programmable thermostat turn on heating or cooling before the wake program begins?   Many Pro1 programmable thermostats have a morning recovery feature that will turn on your heating or cooling before the start time of your wake program so that the room temperature is near your wake setpoint temperature at the time you selected for the wake time period.

Why is there a delay before my heating or cooling comes on?   Some Pro1 thermostats have a built in delay that will last for approximately 5 minutes before heating or cooling is turned on. This feature is used to help protect your system against short cycling.

Why does my heating or cooling continue to run even after the setpoint says to turn it off?  Some Pro1 thermostats have a built in minimum run time feature that will make sure your system always runs for at least 5 minutes every time your system turn on.  This feature is often used to help remove humidity and to keep your system from turning on and then off too quickly.

I have a programmable thermostat but I do not want to use the program, what should I do?  Our programmable thermostats have an override feature that lets you override the program temporarily or permanently.  Your thermostat will be in permanent override if you press the up or down temperature keys and then press the “hold” key. You will notice the word “hold” near your setpoint and now your thermostat will stay at your setpoint temperature until you press “run sched” or turn the system switch to “off”.

Why is my display blank except for the low battery icon?  Your display will be blank except for the low battery icon as a final warning to replace the batteries. You should replace the batteries immediately. Your display will return to normal operation after the batteries are replaced.

Why is my display light not working?  Some Pro1 thermostats will turn off the display light when the batteries are getting low.  The display light will return to normal operation after the batteries are replaced.

What is auto-changeover?   Auto-changeover is a feature on some of our models that automatically selects heating or cooling based upon your program settings.  The user sets the program for heating and for cooling and then put the thermostat in “Auto” mode on the system switch.  The thermostat will then use the programmed settings to turn on heating or cooling as needed. 

There are two important things to remember.

1. When in auto-changeover (auto selected with the system key) mode there must be a minimum of a 2 degree deadband between the heating and cooling setpoint. For example, if the heating setpoint for a given time period is 70 degrees then the cooling setpoint must be 73 degrees or higher.
   
   
2. Your cooling setpoint must always be higher than your heating setpoint for a given time period. 

Does my thermostat use batteries?  Many of our models operate on 2 AA batteries. The thermostat must have batteries to operate.  If you are unsure, you will see a low battery icon in the display when the batteries need replaced.

What kind of batteries should I use in my Pro1 thermostat?  All Pro1 thermostats use 2 AA batteries.  We recommend Energizer brand batteries for the best performance.

How long should my batteries last?  Battery life depends upon the number of on and off cycles and the amount of display light use.  Pro1 thermostats will operate for approximately 1 year before batteries need replaced.  The low battery icon will show in the display when batteries need to be replaced.

You will see a flashing battery icon when your batteries are starting to get low.  This is an early warning that your batteries need to be replaced.   

If this low battery indicator is ignored, the thermostat display will disappear except for the low battery indicator as a final warning before the thermostat becomes inoperable.

On some models, the display light will not work until batteries are replaced.  This feature conserves battery power and also provides a reminder to change the batteries. 

Can I reset my thermostat if it is not functioning properly?  The thermostat has a reset button located on the back of the thermostat.  You can reset your thermostat by holding down this button for 2 seconds. You will see the reset button if you remove the thermostat from the sub base mounted to the wall.  A firm tug is usually required to remove the thermostat from the sub base.
