Our current general terms and conditions apply.Errors, printing faults and technical changes reserved
The flowtemp. setvalues laying between 2 points of the curve are calculated according to this curve.
This applies for a room- temperature of 20°C.
An increase and/or decrease of this setting increases and/or decreases these values by 2 °C per 1°C
roomtemperature change.
Setting aid for the values
"36°C"
,
"55°C"
and
"70°C"
:
If the requested room- temperature is not reached at an outside temperature between +10°C and
+20°C, increase the "36°C" value by some °C.
If the room gets too hot, decrease the value accordingly.
If the requested room- temperature is not reached at an outside temperature b10°C and -5°C,
increase the "55°C" value by some °C.
If the room gets too hot, decrease the value accordingly.
If the requested room- temperature is not reached at an outside temperature between -5°C and -15°C,
increase the "70°C" value by some °C.
If the room gets too hot, decrease the value accordingly.
NOTICE: If an underfloor heating is installed, the values should be set lower – change the values in
small steps (1-2°C each) in that case.
NOTICE: The value "+21°C" is the "Summer / Winter Changeover" threshold (see "H-circ. 1
Temperatures").
