Honeywell CT3500 Programmable Thermostat User Guide
❑ If the thermostat is already mounted on the wall, remove the
thermostat by placing your thumb between the thermostat and
wallplate and pulling the thermostat up and away as shown.
When the batteries are running low, a REPL BAT message flashes
for one to two months before the batteries run out completely.
Replace the batteries as soon as possible once the message
flashes.
IMPORTANT
Although the thermostat has a low battery indicator,
replace the batteries once per year to prevent leakage
and to prevent the thermostat and heating/cooling sys-
tem from shutting down due to lack of battery power in
the thermostat.
If you insert new batteries within 20 to 30 seconds of removing the
old batteries, the system retains the current time and day. If the
M16424
display is blank, the batteries are dead or installed incorrectly. You must reset the time and day. Refer to Set the Clock
for instructions.
As a precaution when leaving home for longer than a month, change batteries before leaving to prevent
the system from shutting down due to lack of power. Always use fresh alkaline batteries. Nonalkaline
batteries do not last as long. They also can leak, causing damage to the thermostat and the wall
surface. Honeywell recommends Energizer® batteries.
STEP 6. SET FAN OPERATION SWITCH
The thermostat fan operation switch, labeled FUEL SWITCH is factory set
in the F position. This is the correct setting for most systems. If your
system is an electric heat system, set the switch to E. The E setting allows
the fan to turn on immediately with the heating or cooling in a system
where the G terminal is connected.
