3.3 PROG, A-B-CCC-CCC
The legal parameters of the meter are determined by Prog, which can only be changed when the verification seal is
broken. The change must then be made at an accreditated meter laboratory.
The A-code indicates whether the flow sensor (V1) is installed in inlet or outlet pipe. As water has a larger volume
at higher temperatures, the calculator must be adjusted for the current installation type. Wrong programming or
installation results in measuring errors. For further details on placing the flow sensor in the inlet or outlet pipe in
connection with heat and cooling meters, see paragraph 5.1.
The B-code indicates the measuring unit used for the energy register. GJ, kWh or MWh are used most frequently,
whereas Gcal is only used in some countries outside the EEA.
The CCC code indicates the calculator’s adaptation to a specific flow sensor type, i.e. the calculation speed and
display resolution are optimised to the selected flow sensor type and at the same time the type approval regulations
concerning min. resolution and max. register overflow are met. The CCC codes are divided into several tables to
give a better survey.
CCC(V1) indicates the CCC code of the flow sensor and is connected to flow sensor input V1 on terminal 9-10-11
(or 10B-11B), which in most applications is the flow sensor used for calculating energy.
CCC(V2) indicates the CCC code of an extra flow sensor, if any, to be connected to terminal 9-69-11 (or 69B-79B).
If V2 is not used, CCC(V2) = CCC(V1). In connection with leakage surveillance CCC(V2) = CCC(V1).
