Heat Curve:
1,0...1,6
The curviture of the curve is solely dependent on the type of heating system.
Example: Heating Curve
Underfloor Heating:
1,1
Column radiators made of cast iron or steel at normal
connection
1,3
Convector Heaters depending on Manufacturer:
1,3...1,6
Flow Temp
Max: 0...120 °C
Here the maximum flow temperature from the mixing valve can be set (eg.
Underfloor heating 40
o
C)
Flow Temp:
Min: 0...120 °C
Here the minimum flow temperature from the mixing valve can be set (eg,
Underfloor heating 30
o
C).
Note:
With a defective external temperature sensor (open or short circuit), the
heating system will operate on frost protection (heating circuit pump = On and
flow temperature is set to ‘flow temp. Min.’ control)
Heating Mixing Valve
Response 1...200
The heating mixing valve response is preset to 100 (for Consolar mixing
valve). This valve will change, either higher or lower, depending on
Manufcturer.
Note:
The larger control parameter entered, the quicker the deviation from the target
temperature will be corrected. However, using a parameter setting which is to
high can lead to the correct target temperatures not being achieved
Safety Function to Prevent the Mixing Valve or the Heating Circuit Pump sticks:
The controller opens and closes the mixing valve and turns on the heating
circuit pump for 30 seconds on a daily basis. This protective function is
activated when the heating circuit pump has been switch off for longer than 24
hours.
