Outdoor temperature sensor (TA):
»
Fit the outdoor temperature sensor at a height of ap-
prox. 2.5 m to the outside wall of the building (on the
north-west side). Make sure that the outdoor temper-
ature sensor is not exposed to direct sunlight or wind,
as this will impair the control characteristics.
i Information
Avoid fitting the outside temperature sensor to the
casing of the outdoor unit or in the air flow from
the outdoor unit.
Buffer sensor (TPO, TPM):
In heat pump buffer tank, two buffer sensors are required.
The heat pump is switched on on the basis of readings
from the TPO and switched off on the basis of those from
the TPM.
»
Install a sensor pocket in the female socket provided
for the upper buffer sensor (TPO)
»
Install a sensor pocket in the female socket provided
for the lower buffer sensor (TPM)
DHW sensor (TB):
OCHSNER DHW cylinders are fitted with appropriate fe -
male sockets for installing the sensor.
»
Install the DHW sensor in the top one-third of the
DHW cylinder (or at the very least in the top half). The
lower the selected position of the DHW sensor, the
larger the switching hysteresis (5-15 K) will need to
be.
i
Information
Ensure that the DHW sensor is correctly positioned
and extends beyond the cylinder insulation into the
interior of the DHW cylinder. This is the only way in
which the temperature can be captured correctly.
Mixer sensor (TMK):
If, in addition to a direct heating circuit, your system also
has a heating circuit with mixing valve, then a mixer sensor
must be installed. The mixer sensor is supplied with the
heat pump, as a contact sensor including band clamp and
heat conducting paste.
»
Install the mixer sensor immediately downstream
of heating circuit circulation pump 2 for the heating
circuit with mixing valve, on a (metal) pipe made of a
good heat-conducting material.
9.5.6 Pumps and servomotors (230 VAC)
Pumps (heating circuit pumps, DHW charging pump) and
servomotors (switching module, mixing valve) are con-
nected directly to the OTE controller (1x 230 VAC power
supply).
Material damage
A test run of the pumps and servomotors may be
conducted only on a system that has been pre-
pared for commissioning. The hydraulics must be
fully connected.
9.5.7 PSU signal contact
Tariff switching on the heat pump system
In the case of tariff switching (with interrupted power deliv-
ery), the heat pump is temporarily shut down by the power
supply utility (PSU).
Uninterrupted tariff
In the case of tariff switching with uninterrupted power
delivery, the heat pump is temporarily shut down by the
power supply utility. A PSU signal contact is provided for
this purpose on the indoor unit. To activate the function,
remove a cable bridge in the control box and connect the
PSU signal contact cable (see „Electrical connection of the
indoor unit“ on page 34).
Shutdown by means of a tariff contactor
In the case of shutdown by means of a tariff contactor in-
stalled on behalf of the customer (sealed by the PSU), the
power supply to the heat pump compressor is disconnect-
ed. Here, it is essential to connect an auxiliary contact to
the tariff contactor (N/C contact) of the PSU signal contact
on the indoor unit.
Night tariff
Where tariff switching takes place within the meter (night
tariff), the PSU signal contact is not connected.
9.5.8 Smart Grid
For the Smart Grid function, special descriptions are avail-
able on request from your OCHSNER Customer Service
department.
