Start-up
Replace the housing cover and press it in gently until you hear all the tabs latch. Open the shut-
off valves. Check the heating system for tightness and vent it carefully.
No more than 100 s later, message F0 will disappear. After that, check that the displays for
flowrate and temperaures are plausible. Vent the system until the flowrate display is stable.
Adjust the system with the flowrate display (updated in the flowrate timebase).
Seal the sensors. Attach user seals to the electronic unit and the sensors.
Read and note down the meter readings for quantity of heat, volume, operating time, and
missing time.
We recommend resetting the maxima and the missing time (see Parameter setting).
In case of
incorrect installation
, the relevant error message will be displayed.
Note: During a system stoppage, such messages may appear although mounting was correct.

Tariff control by means of threshold values
(tariffs “T2”, “T3”, “T4”, “T5”, and “T6”)
The threshold values can be derived from the
flowrate
, the
heat power
, the
return temperature
,
the
flow temperature
or
temperature difference
. Up to 3 tariff thresholds are possible; the
selected measured value aplies to all threshold values. Each tariff threshold is assigned its own
tariff register.
In the tariff registers, it is possible to acquire either the quantity of heat or the volume.
The total quantity of heat and the total volume are summated independently of the tariff
thresholds.

Measured quantities for threshold values:

Summation is performed, if:
Threshold 1 < Meas. value < threshold 2
Threshold 2 < Meas. value < threshold 3
Threshold 3 < Meas. value
