12.3 Types of meters
The meters are used to acquire consumption values.
Pulses from the following types of meters can be handled:
• Gas meters
• Hot water meters
• Cold water meters
• Electricity meters
The pulse values represent:
• Energy in kJ, MJ, GJ, Wh, kWh and MWh
• Volume in m
3
, l or ml
• Variables with no unit (max. 3 decimal places)
• Heat cost unit
• BTU (British Thermal Unit)
The pulses are converted to consumption values according to the setting values and
then added; the cumulated values are stored as 15-month values at midnight when the
month changes. The monthly values of the last 15 months will be stored.
