DESCRIPTION OF OPERATION AND ADDITIONAL POSSIBILITIES

MIXING HEATING CIRCUIT (MC)
Stand-pipe temperature calculation
The upper limit of stand-pipe temperature calculation is set with maximum stand- pipe
temperature Tvmax - parameter S2.7, lower limit is set with minimum stand-pipe tempera-
ture TVmin - parameter S2.6.
If two room temperature sensors are used and the parameters S1.5 and S1.6 are set to
support this configuration, then the average temperature of this two sensors is used for
the correction of calculated temperature for the stand-pipe temperature.
Parameter S2.1 is used to set the influence of room temperature deviation for the calcula-
tion of the stand-pipe temperature, and with the parameter S2.2 you can adjust the paral-
lel shifting of the heating curve.
Mixing valve control
For additional settings of 3-point mixing valve control there are parameters S2.8, S2.9,
S2.10 and S2.11 available.
Heating switch OFF
If the calculated temperature of the stand-pipe isn't at least a little higher than the room
temperature, then the heating is automatically switched off. If the room temperature is not
measured and when the outdoor temperature approaches the required temperature, then
the heating is automatically switched off. The switch off point can be corrected with pa-
rameter S1.12.
At automatic switch off of the heating, a temperature of 4 °C is set for the temperature of
the stand pipe nad the circulation pump UWP is turned off with a 10 min delay. With pa-
rameter S2.5 other possibilities for UWP pump operation can be selected.
Intense - BOOST heating
With parameters S2.3 and S2.4 you can define time and intensity of boost heating, which
is activated at transition from night to day heating interval.
Liquid boiler temperature influence on stand-pipe temperature calculation
If the liquid boiler temperature drops below the minimum boiler temperature, then the cal-
culation of stand-pipe temperature begins to proportionally decrease.
In case liquid boiler temperature exceeds the maximum boiler temperature - parameter
S5.2, then the boiler protection is activated. At this point the maximum boiler temperature
- parameter S2.7 is set for the calculated stand-pipe temperature. The protection is deac-
tivated, when the boiler temperature drops below the maximum boiler temperature.
