Monthly and yearly CP restart, i.e. CP is calculated over just the remaining period until the next logging. Current CP is set to 0.0
until the daily logger has logged across the configured number of days (if the number of days is, for example, set to 5, the
calculator must perform 6 loggings before the calculator can calculate across 5 whole days).
7.2.2
Seasonal Coefficient of Performance (COP)
SCOP is an average measurement of the heat pump efficiency that shows how effective it is on an annual basis. The
average yearly value is measured over one year (one season) where the heat pump has experienced both high and
low ambient temperatures.
When selecting logger profile (RR code), it is possible to save both yearly and monthly values. Monthly values are
calculated as the average of a completed month and yearly values are calculated as the average of a completed year.
Month and year are determined by the selected target date.
7.2.3
Measurement of the coefficient of performance (CP) of a gas boiler
If the pulse output of a gas meter is connected to the calculator, the coefficient of performance of the gas boiler can
be measured, in terms of e.g. kWh/Nm
3
gas. A volume resolution that corresponds to the pulse weighting on the gas
meter pulse output must then be selected for input B1.
