S1:
T1: 74.8 ° c
P1: 0.14 bar
P: 9 W
S2:
T2: 23.9 ° C
Q2: 5.55 l/min
Heat: 19944 Wh
In the submenu “Measured values”, different measurement
val ues are shown: the measured values depend on the sen-
sor type and can be the following:
Sensor 1: T1 (temperature in ° C or ° F)
p1 (pressure in bar)
Q2 (flow rate in l/min, m³/h or gallon/h)
P (in W) – values over 999,999 W cannot be
processed. In such a case, both the displayed
value and the VBus
®
data packet value remain
at 999,999 W.
Sensor 2: T2 (temperature in °C or ° F)
p2 (pressure in bar)
Q2 (flow rate in l/min, m³/h or gallon/h)
Heat (in Wh
, kWh, MWh, kJ, MJ or GJ.
)
Note:
“Power” and “Heat” are only indicated when
at least one of the sensors connected is a VFS
type sensor and the option “Heatmeter” in the
submenu “Adj. values” has previously been set
to “Yes”.
S1 measures the flow temperature, S2 the return
temperature.
If the flow temperature is lower than the return temperature,
heat quantity measurement is not carried out. In that case,
the power is displayed as 0.
