Some electronic thermostats have a fixed, non-adjustable anticipator, and
some can be adjusted by entering the installer setup.

We installed a new FA gas furnace, a Rheem 2 stage model. The

installed a Honeywell digital, programmable Focus Pro TH6220 2-stage
thermostat.
We hate this Honeywell T-stat: When it comes on in the morning, the
temperature at the t-stat rises much more quickly than the room
temperature.
Because the thermostat is usually 4 degrees ahead of the room
temperature it
shuts the furnace off too quickly. The actual room temp may be 70 but
the
t-stat reads 74. Since the t-stat was set to shut off at 74, the
furnace
stops, although the room temp is only 70. It then keeps cycling on/off
and
high/low until it reaches 74 degrees 2 hours later.
Not being familiar with that thermostat I can't say anything intelligent,
but
Does it have an anticipator? Most thermostats have a tiny heater
inside to heat the thermostat so when the furnace turns on, it can
"anticipate" the rise in temperature without waiting for the air to heat
it.
They are adjustable for different situations.
