Information level
In addition, the Info sequence shows
the total heat gain (ERT), the daily heat
gain (ERTd) and the speed of pumps
P1.. P3 (ED1..ED3).
It is preferable to use a volume flow
sensor for the total or daily heat gain
calculation. Parameter
VSA
= 1 or 2
(E3 - 4 / 3) confirms that a volume flow
sensor is being used. The heat gain
display is enabled when confirmation is
received that a volume flow sensor is
present. If no volume flow sensor is
present, heat gain values can only be
displayed if the minimum lower set
point for the heat transfer pump is set
to 100 percent. In this situation the heat
gains are calculated on the basis of the
default liquid flow rate.
ERTA
total heat gain in kWh;
cumulative annual heat gain
range: 0 .. 199999 kWh
Total heat gain can be reset to zero by
pressing and holding the [-] key for five
seconds while a value is being dis-
played.
ERT0
previous day's heat gain
in kWh;
previous day's heat gain displayed
range: 0 .. 999 kWh
Heat gain can be reset to zero by
pressing and holding the [-] key for five
seconds while a value is being dis-
played.
ERTd
daily heat gain in kWh;
Shows the running total for the day's
heat gain. The total is reset to zero at
12:00 a.m.
range: 0 .. 999 kWh
The day's heat gain can be reset to
zero by pressing and holding the [-] key
for five seconds while a value is being
displayed.
