TARIFF TYPES
E=0 No tariff active
If you do not wish to use the tariff function, select set-up E=0.
However, the tariff function can be made active by reconfiguring by means of METERTOOL for MULTICAL
401. See section 14.1 Programming with METERTOOL.
E=1 Power controlled tariff
If the actual heat flow rate, in kW, is higher than TL2, but lower than TL3, the thermal energy will be
counted in TA2 and in the main register. If the actual power exceeds TL3, thermal energy will be counted in
both TA3 and the main register.
P
TL2
Counting in main register only
TL3 P TL2
Counting in TA2 and main register
P TL3
Counting in TA3 and the main register
Table 9
During set-up of data, TL3 must naturally be higher than TL2.
Among other things the power controlled tariff is used as a basis for calculating the individual heat
consumer’s connection costs.
Furthermore, this tariff form provides valuable statistical data when the utility evaluates new construction
activities.
E=2 Flow controlled tariff
When the actual water flow (q), in l/h or m
3
/h is higher than TL2 but lower than TL3, thermal energy will be
counted in both TA2 and the main register. If the actual water flow exceeds TL3, the thermal heat is
counted in TA3 and the main register.
q
TL2
Counting in main register only
TL3 q TL2
Counting in TA2 and main register
q TL3
Counting in TA3 and main register
Table 10
During set-up of data, TL3 must naturally be higher than TL2.
Among other things the flow controlled tariff is used as a basis for calculating the individual heat
consumer’s connection costs. Furthermore, this tariff form provides valuable statistical data when the
utility evaluates new construction activities.
When power or flow tariff is used it is possible to get a total overview of the total consumption compared to
the part of the consumption that is used above the tariff limits.
