Every time you change the temperature display format, the
comfort and economy preset temperatures return to their
default settings.
b
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.
