“If I am away for an extended time such as vacation, how do I set 
the thermostat so my system does not run excessively?” 

You have  a couple of choices.  The first is to press  the 

HEAT/COOL

 

button on the thermostat until the display reads 

“OFF."  (During the heating season, we do not recommend going to 
the “OFF” mode.)  The second option is to put your thermostat in 
manual mode by pressing the 

RUN

 button.  You know  that  you are 

in the manual mode  because none of the period icons, 

Morning

Day

Evening

, or 

Night

 will be showing (Refer to Figure 6).  Next, 

adjust the  set  point temperature  to minimize  system  operation.  For 
example, you could adjust to a set point of 88

°

 in cooling or 55

°

 in 

heating, staying mindful of what your temperature selection could 
affect such as plants and animals that stay in your home while you 
are away.  During the cooling season, consider humidity as well as 
indoor temperature.  When your air conditioner runs it not only cools 
the air, it also removes moisture, lowering humidity.  High humidity 
can encourage the growth of mold as well as  other undesirable 
effects. 
 

“How can I save energy with my T9000 thermostat system?” 

The T9000 was designed to provide precision temperature control.  
That  alone  can save energy since your system will be tightly 
controlled to within a degree or two of your desired  set point.  
Studies have shown you can save up to 12% just through precision 
temperature control. 
 
You can maximize savings if you  also  program your thermostat to 
automatically turn the temperature up or down while you are away or 
asleep.  See the PROGRAMMING section of this guide for exact 
details.  

“The display on my thermostat is blank.  What happened?” 

A blank display indicates that your batteries are depleted.  When the 
“Low Battery” or 

icon  is on, there  is 1 or 2 weeks of 

battery life  remaining.  See the  INSTALLING/CHANGING 
BATTERIES section of this guide for information on how to change 
the batteries.  Keep in mind that if your thermostat loses battery 
power, it no longer controls your heating/cooling system.  We 
recommend that when you change batteries, always use batteries that 
you know are fresh.  Use four (4) batteries for longest operation.  If 
you are using the T9000 to control a heating system, we recommend 
putting fresh batteries in at the start of the heating season. 
 

“Can I run multiple heating or cooling loads such as electric 
baseboard heating and a window air conditioner with one T9000 
thermostat?” 

Yes.  In fact  one T9000 thermostat can control  up to eight (8) 
different RCNs.   
 

“Can I have a second thermostat controlling another load 
without interference from my first thermostat?” 

Yes.  A T9000 thermostat and its RCN(s) will talk between 
themselves, but will never respond to another thermostat or 
controller in adjacent rooms, apartments, or neighboring homes.
