Remarks of Siemens

This section outlines how Siemens interprets the functions and processing functions according

to EN 15232-1:2017.

5) The following main features distinguish TABS from other heating and cooling systems:

· TABS is a low-temperature heating/high temperature cooling system

· TABS activates relatively large thermal storage

These features permit energy-efficient operation in a number of cases

6) As a rule, there is only a single flow temperature setpoint per zone (heating and cooling – no

setpoint range. This means: Frequently slight overheating or undercooling during transition

periods (where heating and cooling are released).

7) A setpoint range is used here; one setpoint each can be preset separately for heating and

cooling. This eliminates to some extent overheating or undercooling.
