5.15. Energy counter
The Energy Counter function lets you calculate the total
energy transferred to the load and estimate its cost.
The Energy Counter function can be linked to two controller
outputs. The count is run only if the chosen output has HEAT
/ COOL function.
You can display the following information on the user confi-
guration menu:
• Load current (parameter CURR). This is measured di-
rectly if the CT1 or CT1+CT2 option is present. CURR is
expressed in amfores and can have values from 0.0 to 99.9.
• Power on load, parameter OU.KW_1 (or OU.KW_2), cal-
culated in kW. Power is calculated:
o if nominal power is not zero, based on nominal power
P.LOAD_1 (identical for P.LO_AD_2), as % of same
o if nominal power is zero, by using line voltage
V.LINE_1 (or V.LINE_2) and current (here as well,
considering PID power %)
OU.KW_1 (identical for OU.KW_2) can have values
from 0.00 to 99.99.
• Time taken to count energy (parameter E.TIM_1 or
E.TIM_2) value from 0 to 999 hours
• Energy on load (parameter O.KWH_1 or O.KWH_2)
value from 0.00 to 99.99 kWh
• Energy counter transferred to load (parameter E.KWH_1
or E.KWH_2), calculated in kWh.

E.KWH_1 (identical for E.KWH_2) can have values from
0 to 9999.
The energy count does not depend on the output type,
and is also done for continuous outputs (A for 850 and C
for 1650 /1850).
The energy count stops when it reaches the maximum
of 9999 kWh or maximum time E.TIM_1 (or E.TIM_2)
at 999 hours. The count is not linked to output type.
• Cost of energy transferred to load (parameter E.CST_1
or E.CST_2). Cost is calculated based on nominal cost
of energy for kWh (parameter E.COST_1 or E.COST_2)
by using the formula E.CST_1 = E.KWH_1 × E.COST_1
(or E.CST_2 = E.KWH_2 × E.COST_2). E.CST_1 (iden-
tical for E.CST_2) can have values from 0 to 9999 (with
rounding-off to 0.5).
