Table 1 shows the configuration of the switches on the
back of the front module. Default settings are inside
the shaded cells.

Every time you change the temperature display for-
mat, the comfort and economy preset temperatures
return to their default settings.

For hot water installations, it is recommended to
enable this function to activate the pump for
one minute every 24 hours to prevent pump seizure.

Temperature Control Mode

Choose proportional adaptive mode by placing switch
#5 in the up position for these types of systems.
• Hot water heat systems
• Gas, oil, or electric furnaces
• Electric radiant or convection heating
See Table 2 to set switches #1 and #2 for how to
configure proportional adaptive mode.
Choose conventional mode by placing switch #5 in
the down position for these types of systems:
• Gas or oil furnace or boiler with a 30-second or
longer combustion gas prepurge cycle. To figure
out the gas purging cycle of your system, measure
the time lapse from the instant the thermostat
sends the heating command to the instant the
burner actually goes on.
• Systems where the user desires to set how many
degrees the air temperature must fall before the
thermostat calls for heat. In general, the slower the
HVAC system is able to distribute heat, the smaller
the the differential should be.
• When more than one TL8100 is wired directly to
one zone valve or one zone circulator.
See Table 3 to set switches #1 and #2 for how to
configure conventional mode.

POWER-UP
When you install the batteries, the unit
performs a series of tests for a few
seconds before displaying the ambient
temperature.
It is normal that the displayed
temperature be higher than the ambient
temperature if you are holding the
thermostat. Once installed on the wall,
the thermostat will display the true
ambient temperature after one hour.
