120 0 Heat Flow Function
To determine the steam or hot water flow, the heat flow expansion feature
must be unlocked. Up to 3 temperature sensors (T1, T2 and T3) are used
for steam or hot water flow metering depending on what heat flow function
is set. T1 is wired to terminals T1 and -, T2 to terminals T2 and -, and T3 and
-. See Expansion Features Installation and Commissioning Guide.

7 Hot water flow with default values
8 Hot water flow
9 Hot water flow with economiser
121 100 Boiler Standing Losses
The boiler standing losses are known as the heat lost from the boiler
surfaces and pipework through radiation, and is set as a percentage of the
maximum continuous rating of the boiler.
0 – 200 0.00 – 2.00%
122 100 Blow Down Losses
This is the typical losses resulting from top blowdown and bottom
blowdown.
0 – 100 0.00 – 10.0%
123 0 Blow Down Loss Calculation Method
For setting 0, a fixed blow down loss is used in the steam or hot water flow
metering, set in expansion option 122. For setting 1, the blow down loss
will change according to the current firing rate in the metering calculation.
0 Fixed loss
1 Loss proportional to firing rate
124 100 Make Up Flowmeter Range
The make-up flowmeter range is only relevant if the steam flow metering
function has been set with deaerator in expansion option 120.
0 – 9999 0.0 – 999.9 litres/s or gallon/s (see parameter 40)
125 100 Condensate Flowmeter Range
The condensate flowmeter range is only relevant if the steam flow metering
function has been set with deaerator in expansion option 120.
0 – 9999 0.0 – 999.9 litres/s or gallon/s (see parameter 40)
126 80 Default Feedwater Temperature
If the heat flow function is set for steam or hot water flow metering using
default values, then this default feedwater temperature is used for the steam
or hot water flow metering calculations.
0 – 300
