Dil Switch Settings - Secure SRT321 User And Installation Instructions Manual

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.
DIL switch numbers 7 and 8 should be
Ÿ
set as diagram opposite.
For Gas boilers set the TPI setting to 6
Ÿ
cycles per hour. (Default setting)
For Oil boilers set the TPI setting to 3
Ÿ
cycles per hour.
For Electric heating set the TPI setting
Ÿ
to 12 cycles per hour.
