If in vacation or economy/absent mode, or if
ECO is selected at PARA 1, the boiler will fire if
this temp is detected by the RS100 (in the room).
NOTE
: If the RS100 is set for outdoor reset mode (PARA 3=OFF or 1, PARA 4=OFF), a modem-driven
switch can be placed in parallel with the outdoor sensor. When this switch closes, the RS100 will use
this parameter to engage freeze protection. This allows a user to remotely preheat a second home.
