The power supply 230V~ to the OTE control is on the
terminal strip X1 in the Airstation distribution box (L N
PE). This ensures that the OTE and the control in the
Airstation distribution box have the same phase and
neutral. This cable, as well as the signal cable between
OTE and the Airstation distribution box is already fitted
in the functional module and only has to be connected
to the Airstation distribution box with the flat connect-
ors (L, N) and to the earthing block (PE).

7.3 Switching off via tariff relay:
For switching by means of a tariff relay (sealed by the
Utility on site) the 3-phase power supply to the heat
pump is switched off. The heat pump signal contact
must be executed via the auxiliary contact on the tariff
relay
7.4 Utility control contact
In the case of tariff switching (interrupted power sup-
ply) the heat pump will be temporarily switched off by
the utility. For this, the control input Utility (PIN 21) is to
be connected to the control in the heat pump.
The appliance is delivered with PIN21 connected to
PIN 12 on the OTE. When using the Utility control
contact, this cable is disconnected from both PINs and
the Utility control contact connected to PIN 21.
7.5 Control wiring
Digital signals will be transmitted between the control
(OTE) and the Airstation A 5-pole control cable (W5 =
5x 1.0mm²) is used for this. This is already fitted in the
functional module and only has to be connected to the
Airstation distribution box.
1. Wire OTE Pin.11 --> DHC1 and DHC2
2. Wire OTE Pin.20 --> De-icing
3. Wire OTE Pin.4 --> RESET
4. Wire OTE Pin.24 --> HP-ON
5. Wire OTE Pin.19 --> working (Relay K1/A1)
7.6 eBus wiring
An eBus connection is required
between the OTE control and the auxiliary OTE mod-
ule or to the room remote controls and the room termi-
nal with Touch Display.
The communication between the eBus users is by
means of 4 x 1.0mm² wire.
For instance: EIB 4x0.8mm², whereby 2 wires can be
used together, thus providing a cross-section of >=
1.0mm². Ochsner recommends using sheathed wiring.
7.7 Sensor wiring
Do not place line voltage on the sensor
terminals! The control will otherwise be
destroyed.
The Type NTC5K temperature sensors of the OTE
control are supplied with 4.0m cables. Should this
4.0m not suffice, the cables can be extended to the
length required. Please use 2x 1.0mm² flexible cable.
When installing the sensor cable, ensure that the ca-
bles do not run parallel to alternate current >230VAC
cables.
Buffer sensors (TPO, TPM)
A minimum of 2 immersion sensors are to be installed
in the sleeves in the buffer tank. When selecting the
length of the immersion sleeves, take the thickness of
the insulation into consideration as well. 2 buffer sen-
sors are to be used:
Top buffer sensor
(TPO)
Middle buffer sensor (TPM)
