4.3.6 “Smart Grid”
function via the
Heat Pump Manager
In conjunction with the Aquarea Heat Pump Manager (HPM), Aquarea
heat pumps can be integrated as intelligent heat pumps in an intelligent
power grid and their operating states can be adjusted to suit current
requirements, via control signals from the electricity provider.
Intelligent heat pumps must be able to implement four different operating
states, as specied by the electricity provider. The operating states are
signalled to the HPM via two signal contacts. Each signal contact (Inp1
and Inp2) can assume a status of 1 (On) or 0 (Off), resulting in the four
possible operating states described below.
