DIL Switch Settings – TPI Temperature
Control Software
Thermostats using TPI (Time Proportional Integral)
control algorithms will reduce the temperature swing
that normally occurs when using traditional bellows or
thermally operated thermostats.
As a consequence, a TPI regulating thermostat will
maintain the comfort level far more efficiently than any
traditional thermostat. When used with a condensing
boiler, the TPI thermostat will help to save energy as
the control algorithm allows the boiler to operate in
condensing mode more consistently compared to
older types of thermostat.
