Finally everything is about cost. So how to get a return on investment for an LM and meters? I use the following not profiled cost analysis for a return on investment for an unrecognized air heater pump error (for homeowners) based on values on an energy meter that measures the consumption of the compressor heat pump unit. Then I turning the air heater pump for 2.5 days off and getting the manufacturer kWh max. use over 24 hours of electrical heating in the main heat buffer of the heating system (the energy use of the emergency system). So it is an assumption because room temperatures changed slightly and the energy demand of the emergency system is an assumption.
So in acceptance (unconfirmed): If the manufacturer's system control does not receive an error possibility on optimisation and the following device receives getting a abnormality in the system so it will by fixed, which may leads to add. costs, the refund by less than + 5 ° C outside temperature and a heat pump greater than 8 kWh will by approximately for the Hardware (excl. installations costs):
A singel Nano temperature sensor POE = 0.3 month in winter season (by less than +5°C)
Logic machine 5 lite = 3 month in winter season (by less than +5°C)
Energy meter TCP / IP = 3 month in winter season (by less than +5°C)
Heat meter TCP/IP = 6-8 month in winter season
and this month are without depreciation of additional wear and tear by errors on the air heater pump.
