All Grant Aerona Heat Pumps are
supplied with 2 controllers. 1 x heat
pump controller (ATC) and 1 x
temperature controller (BTC).
The ATC is positioned inside the
house/building and is normally used in
an automatic condition. There are a few
parameters that can be adjusted
including time and maximum water
temperature. The details of these
settings can be found in Section 11 of
this manual.
The BTC is a split temperature
controller located inside the heat pump.
For many installations, the DHW
temperature and the CH temperature
will be different. The BTC allows for 2
different design temperatures to be
entered, maximising the efficiency of the
Grant Aerona heat pump. The details of
these settings can be found in Section
11 of this manual.
All other controls (programmers,
motorised valves, thermostats, etc) are
not supplied but their use is covered in
Sections 4 and 8 of this installation
manual.
