Setup
Installation Guide CT100
• Always use new Alkaline batteries.
• Do not use rechargeable batteries of any type. They will no operate the
thermostat properly and may lead to damage.
• Do not mix old and new batteries.
• Do not mix battery types, for example Lithium with Alkaline.
• Do not dispose of batteries in fi re. Batteries may explode or leak.
• Always replace the batteries as soon as the “Low Batt” warning fl ashes. The
thermostat is a battery-powered device; you should replace the batteries
before they run out, as failure to replace batteries can result in excessive
heating or cooling of your house.
• Always replace the batteries once a year, even if the “Low Batt” indicator
does not fl ash. Replacing the batteries also helps to prevent leakage that
can corrode and damage the thermostat.
• If you are leaving your home for a month or more, you should replace the
batteries as a precaution against battery failure in your absence.
• Failing to replace the batteries when necessary could cause the thermo-
stat to lose power or malfunction. If the thermostat loses power, then the
thermostat will not control the temperature, which could result in your HVAC
system not functioning as you intended and lead to possible damage from
excessive heating or cooling.
• If the thermostat batteries fail with the heat OFF, this can result in NO HEAT
and possible frozen or broken pipes and water damage.
• If the thermostat batteries fail with the cool OFF, this can result in NO COOL
and could cause possible damage or excessive temperatures.
