Several installation devices are controlled from the heat pump electrical panel. Some are internal and other are installed externally.
The internal components are connected to the electrical panel in the factory. Depending on the installation that the heat pump is
going to be connected to, in addition to the power supply, it may be necessary to connect various temperature probes (analogue
inputs AIxx), control signals from thermostats or other external equipment (digital inputs DIxx) on/off switching of pumps and/or
valves (digital outputs DOxx) or regulation of pumps and/or valves (analogue outputs AOxx).
The figure below shows a sample installation with the options for connecting external components to the heat pump.
