Display of the current temperature differential between the flow and
corrected return temperature, which is critical for the heat meter
➢ PLEASE NOTE: The meter readings from the Heat meter function module are saved to the
internal memory every hour. Therefore, in the event of a power failure, no more than 1 hour
of metering can be lost.
➢ When loading function data, you will be asked whether you want to apply the saved counter
readings (see manual Programming Part 1: General information).
➢ If the flow temperature is lower than the return temperature, the meter will count negative
energy if the reversing block is set to No. The meter reading will be reduced as a result.
➢ The changeover of the Week meter occurs on Sundays at 24:00 h.
