Siemens RDG100…/RDG110…/RDG140.../RDG160… Basic Documentation CE1P3076.en
Building Technologies Functions 19 Jun 2009
The RDG1xx.. can also be used on universal applications, e.g. fan coil-based
cooling and floor heating, or chilled ceiling and electrical heater, etc.
For more detailed information, refer to subsection 4.7.9 ff.
4.6 Additional features
The water temperature acquired by the changeover sensor (QAH11.1 + ARG86.3)
is used to change over from heating to cooling mode, or vice versa. When the
water temperature is above 28 °C (parameter P37), the thermostat changes over to
heating mode, and to cooling mode when below 16 °C (parameter P36).
If the water temperature is between the 2 changeover points immediately after
power-up, the thermostat starts in heating mode.
The water temperature is acquired at 30-second intervals and the operating state is
updated accordingly.

temperature sensor (QAA32), or external return air temperature sensor (QAH11.1)
connected to multifunctional input X1 or X2.
Inputs X1 or X2 must be commissioned accordingly. See section 4.10 “Multi-
