ATTENTION:
The meter readings from the Heat meter function module are saved to the inter
-
nal 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 lock 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.
