For the control of the primary return temperatures (B7, B71, B72), it is also possible to
use commercially available sensors with Pt 500 sensing elements.
• For the outside temperature:
Outside sensor QAC22 (sensing element LG-Ni 1000)
−
Outside sensor QAC32 (sensing element NTC 575)
−
• For the room temperature:
PPS-compatible sensors must be used. The following types are available:
Room temperature sensor QAA10
−
• For the storage tank temperature:
Cable temperature sensor QAP21.3
−
Immersion temperature sensors QAE2...

Suitable room units

• Room unit QAW50
• Room unit QAW70
1.3.3

Suitable valve actuators

All types of actuators from Siemens with the following features can be used:
• Electric or electrohydraulic actuators with a running time of 10...900 seconds
• 3-position control
• Operating voltage AC 24... 230 V
1.3.4

Communication

Communication with other devices, controllers, etc., is possible:
• Via LPB, e.g. assignment of d.h.w., reception of radio signal, master / slave assign-
ments for the time switch, reception of heat demand signals (RVD230 used as a pri-
mary controller, reception of outside temperature signal)
• Via M-bus, e.g. reading setpoints and actual values, or output control for space heating
