801 has 2 extra registers, TA2 and TA3, which can accumulate heat energy E1 (EE=20 accumulates
volume) parallel with the main register based on the limits programmed for tariff limits TL2 and TL3.
Example: EE=11 (Power tariff)
TA2 shows energy consumed…
…above the power limit TL2

Power tariff
Energy is accumulated in TA2 and TA3 based on the power limits
in TL2 and TL3.
•
•
12
Flow tariff
Energy is accumulated in TA2 and TA3 based on the flow limits in
TL2 and TL3.
•
•
13
T1-T2 tariff
Energy is accumulated in TA2 and TA3 based on the
∆
t-limits in
TL2 and TL3.
•
•
14
Inlet temperature tariff
Energy is accumulated in TA2 and TA3 based on the tF-limits in TL2
and TL3.
•
•
15
Outlet temperature tariff
Energy is accumulated in TA2 and TA3 based on the tR-limits in
TL2 and TL3.
•
•
19
Time controlled tariff
TL2=Start time for TA2
TL3=Start time for TA3
•
•
20
Heat/cooling volume tariff
(TL2 and TL3 are not used)
Volume (V1) is divided into TA2 for heat (T1
>
T2) and TA3 for
cooling (T1
<
T2). (Recommended for heat/cooling applications)
•
•
•
21
PQ-tariff
Energy if P
>
TL2 is saved in TA2 and energy if Q
>
TL3 is saved in TA3
