BA ROTEX A1 BG Inline - 10/2007
By cascading from the heat circuit expansion modules THETA HEM1 ( 15 60 61), the system can be expanded by up to
5 mixer circuits and/or storage tank charging circuits. The required temperature sensors need to be ordered separately (mixer
circuit contact sensor TMKF ( 15 60 62), storage tank temperature sensor TSF ( 156063)).
Room control (optional)
A separate room control THETA RFF ( 15 40 70) can be connected for each heating circuit for a remote setting of modes
and room temperature from other rooms.
Room station (optional)
All temperature values and modes of the control unit THETA 23R (central unit) can be displayed and changed through the room
station THETA RS ( 15 70 18). Apart from the chimney sweep and manual operation function, all operating elements
(display, keys, rotary switch and functions (e.g. timer programs)) are identical to those of the central unit.
The room station THETA RS can be installed in a suitable place in the building and can be used for the remote operation of the
boiler control.
2.5 Hot water storage tank (not included in scope of supply)

Furthermore, the ROTEX Solaris System can be included in the hot water preparation.
