4.4.9 Opening the control housing and establishing
electrical connections
4.4.10 Connection of exterior heat pump unit RRLQ
Ɣ Dismount the protective cover (see section 4.4.8).
Ɣ Connect the exterior heat pump unit to the terminal strip
XAG1 (see fig. 4-20, fig. 4-22).
4.4.11 Connection of external temperature sensor
RoCon OT1
The exterior heat pump unit of the ROTEX HPSU compact has a
built-in exterior temperature sensor which is used to regulate the
inflow temperature depending on the weather, with frost pro-
tection function.
With the optional outside temperature sensor RoCon OT1
( 15 60 70),
which is installed on the north side of the building,
you can optimise the weather-dependent flow temperature
control.
Choose a location at about one third of the building height
(minimum distance from floor: 2 m) at the coldest side of the
building (North or North-East). Thereby, exclude the proximity of
external heat sources (chimney, air shafts) and direct sunshine.
Ɣ Place external temperature sensors in such a way that the
cable exit points face downwards (prevents humidity ingress).

stor
age container.
This component has a separate manual attached,
including among other things instructions for installation
and operation.
Fig. 4-22 Connection of exterior heat pump unit
When switching off the heat pump exterior unit using a
switching system prescribed by the energy supply com-
pany (EVU), the internal
ROTEX HPSU compact
device is not disconnected (see section 4.4.20).
If the ROTEX HPSU
compact is used in a CAN bus
system as a master ("terminal function" for the remote
control of other data bus devices), the exterior temper-
ature sensor Ro
Con OT1 must be connected directly
to the regulator RoCon HP on the master and not to
the remote controlled device (mixer circuit module
RoCon M1 or a different heat generator).
CAUTION!
The parallel routing of sensor and mains lines within
an installation pipe can cause considerable malfunc-
tioning in the regular opera
tion of the ROTEX HPSU
compact.
Ɣ Always lay the sensor line separately.
