5.4.4. Analog output signals
According to picture from chapter 5.6.1., two output signals are used.
AO1
–
analog signal of active
power steps (0
-10
VDC)
The output
signal value
is approximated
to currently active number of power
steps
.
N
umber of active power steps
corresponding to measured
output value according to formula
below:
U
1
–
output
direct voltage
signal
value
[V]
L –
number of active power steps
L
M
–
maximum
number of power steps
depending
on type of boiler (3, 7 or 15)
AO2
–
analog signal of current boiler temperature (0
-
10VDC)
The output
signal value
is approximated
to current
temperature in range of 0⁰C to 100⁰C
.
Current temperature corresponding to measured
output value according to formula below:
U
2
–
output
direct voltage
signal
value
[V]
T
b
–
current
boiler temperature [
O
C
]
