Temperature Control Span

It controls how much the room te mperature can be dev iated from the
setpoint. A smaller degree will resul t in a more accurate con trol. A
larger degree will result in less on/ off cycling and it usually saves more
energy.

Fan Control

It should be set according to the typ e of Heating system used. Select
“E” for Electric Heat, fan wi ll be On when Heat is On. Select “O” for
Gas Heating or Oil Heating, fan w ill NOT be on when Heat is On.

Heater Minimum Off Delay

It should be set according to the hea ter type. Select “L” if compressor

is used for heating. Select “S” when a co mpressor is not used.
