Outdoor reset
Outdoor reset is a smart way to economically
control space heating based on outdoor tem-
perature. It functions based on the fact that the
colder the weather the greater the heat loss of
a structure, and the higher the supply water
temperature needed to heat the house. On a
warmer day with smaller losses a lower water
temperature will be able to heat the house.
Outdoor reset is the preferred control when
using multiple zones, as the boiler supply
water temperature is not dictated by a master
or largest zone, but solely based on the heat
loss of the structure.
Heating curve
The AM10 has a built in linear heating curve
that sets the supply water temperature in rela-
tion to the outdoor temperature.
The maximum supply water temperature set
on the boiler dial works as a high limit. The
boiler will follow the heating curve in the AM10
up to the high limit.
1.3 Mounting of the AM10
The AM10 module should be mounted inside
a GB142 boiler above the controls.
