Caution
Special Thermostat Battery Cautions
Always replace the batteries as soon as the “Low Batt” flashes. The thermostat is a battery powered device.
You must be responsible to replace batteries before they run out. Failure to replace batteries can result in
overheating or excessive cooling of your house.
• Even if the “Low Batt” indicator does not flash, you should always replace the batteries at least once a year.
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.
• Always use new alkaline batteries.
• Failing to replace the batteries, when necessary, could cause the thermostat 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 overheating or excessive 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.
HVAC Selection
• Set the
HVAC TYPE
switch in the
NORM
position if you have normal natural gas,
propane, oil, or electric heat. If you have a HEAT PUMP system set the
HVAC
TYPE
switch to
HP
. They are located under the top cover on the left.
• Set the
HEAT TYPE
switch in the
GAS
position if you have normal gas or oil heat
or if you have a heat pump with gas or oil auxiliary heat. Put the
HEAT TYPE
in
the
ELEC
position if you have normal electric heat or if you have a heat pump with
electric auxiliary heat.
Install 4 AA Batteries
• Install 4 AA alkaline batteries [required] following the
marked polarity in the battery compartments. Put the battery
in negative end first against the spring, then push the
positive end in.
IMPORTANT:
Press the RESET button (under top cover)
to implement the HVAC switch selections.
• With all the wires connected it is time to turn the AC power
back on. Do this at the breaker you used to switch it off. The CT32 will power-up in the OFF mode. Your CT32 is
not configured to operate your HVAC system yet. You must now configure your thermostat for your HVAC
system.
