4.2 Weather characteristics.
The temperature of the installation water needed for maintaining constant room
temperature depends mainly on the outside temperature and thermal characteristics of
the given building. The UMS-4PS unit enables the user to set the adequate inclination
and change the weather characteristics. The relation between the outside temperature
(or averaged outside temperature), the set parameters and the programmed water
temperature of central heating system is shown in picture 2.

system, Maximum temperature in central heating circulation, e.g. 90°C, Outside
temperature [°C].)
