Weather-dependent curve

5.9.1

What is a weather-dependent curve?

Weather-dependent operation

The unit operates 'weather dependent' if the desired leaving water or
tank  temperature  is  determined  automatically  by  the  outdoor
temperature.  It  therefore  is  connected  to  a  temperature  sensor  on
the  North  wall  of  the  building.  If  the  outdoor  temperature  drops  or
rises, the unit compensates instantly. Thus, the unit does not have to
wait  for  feedback  by  the  thermostat  to  increase  or  decrease  the
temperature  of  the  leaving  water  or  tank.  Because  it  reacts  more
quickly,  it  prevents  high  rises  and  drops  of  the  indoor  temperature
and water temperature at tap points.

Advantage

Weather-dependent operation reduces energy consumption.

Weather-dependent curve

To  be  able  to  compensate  for  differences  in  temperature,  the  unit
relies on its weather-dependent curve. This curve defines how much
the  temperature  of  the  tank  or  leaving  water  must  be  at  different
outdoor  temperatures.  Because  the  slope  of  the  curve  depends  on
local  circumstances  such  as  climate  and  the  insulation  of  the
building, the curve can be adjusted by an installer or user.

Types of weather-dependent curve

There are 2 types of weather-dependent curves:

▪ 2-points curve

▪ Slope-offset curve

Which type of curve you use to make adjustments, depends on your
personal  preference.  See 

"5.9.4  Using  weather-dependent

curves"

Availability

The weather-dependent curve is available for:
