4.5.8 Connection of ERLQ exterior heat pump unit

This component has a separate manual attached,
including among other things instructions for installation
and operation.
Dismount the protective cover (see section 4.3).
Connect the exterior heat pump unit to the terminal
strip XAG1 (see fig. 4-27, fig. 4-29).
Fig. 4-29 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 Daikin Altherma EHS(X/H)
device is not disconnected (see section 4.5.18).
4.5.9 Connection of external temperature sensor
RoCon OT1
The exterior heat pump unit of the Daikin Altherma EHS(X/H) has
a built-in exterior temperature sensor which is used to regulate
the inflow temperature depending on the weather, with frost pro-
tection function.
The weather-controlled flow temperature regulation can be opti-
mised with the RoCon OT1 optional external temperature probe,
which can be installed on the north face of the building.
If the Daikin Altherma EHS(X/H) 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 RoCon OT1 must be connected directly
to the regulator RoCon HP on the master and not to
the remote controlled device (mixer circuit module
EHS157068 or a different heat generator).
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.
Place external temperature sensors in such a way that the
cable exit points face downwards (prevents humidity ingress).
CAUTION!
The parallel routing of sensor and mains
lines within an installation pipe can
cause considerable malfunctioning in
the regular operation of the Daikin
Altherma EHS(X/H).
Always lay the sensor line separately.
