“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.
