FA ROTEX HPSU compact 308 - 02/2012
2.4.5 Connection of room thermostat
This component has a separate manual attached, including among other things instructions for installation and
operation.
The connection of the room thermostat to a ROTEX HP convector is described in section 2.4.6.
Installation without room thermostat:
The cable bridge- mounted on-site - is recommended by ROTEX as otherwise problems may arise due to the
cyclical circulation pump during heating operation. The DIP switch 3 (see tab. 3-1, chapter 3 "Start-up") must
be set to "ON".
The absence of a summer switch-off on the circulation pump can be compensated for by manually switching off
heating in the summer (key
) when a cable bridge is mounted.
