1General
The following manual is intended to be a
support for the operation of OCHSNER
heat pumps which are equipped with the
OCHSNER Tronic Easy © (OTE) heat
pump control.
The precautionary pointers below will be
used in this document.
WARNING
Pointers which, if not heeded, can mean
danger to life and limb, and can also lead
to material damage. These pointers must
be heeded without fail.
ATTENTION
Pointer which, if not heeded, can lead to
an appliance malfunction and to material
damage (to system components, building,
...). These pointers must be heeded with-
out fail.
Tips which are intended to aid the job in
hand, or mean additional information for
the user.
1.1 Proper use
The control has been designed so that it
can be deployed in many different sys-
tems. It is thus possible that not all the
functions described here are used in your
system and accessories (such as sensors,
room remote controller etc.) are not in-
cluded in the scope of delivery.
The control may only be used for
the following purposes:
•Energy processing via heat pumps
and/or additional energy generators
(oil/gas/electricity).
•Hot water heating for hot water stor-
age tanks.
•Heating or cooling operation for direct
circuits and/or mixing circuits.
Any further uses are not recognised as
proper. OCHSNER accepts no liability for
possible damage (non-compliance with
instructions).
1.2 CE-Labelling
The product you have purchased con-
forms to the technical regulations valid at
the time of manufacture, and is CE-
conform.
NOTE

BA_OTE 3+4_Endkunde_EN_V03_20170726.docx Page 4 of 52
2Safety instructions
Read this manual carefully before you
begin to adjust the heat pump.
Converting or altering the appli-
ance is not allowed. Work on
the appliance (repairs, altera-
tions) may only be carried out
by the manufacturer or by a
specialist authorised by the
manufacturer.
All circuit breakers in the heat-
ing system are to be turned off
before any work is carried out
on the terminal strips or electri-
cal connections (wiring). The
heating system consists of the
control, the auxiliary modules
and the components that are
connected to the control (heat
generator, pumps, safety ther-
mostats, etc.)
ATTENTION Danger to life and
limb!
Contact with the terminal strips,
wires connected to them, or
non-connected wires by persons
or by means of electrically con-
ductive materials is prohibited,
as the terminal strips could be
live (danger of contact with live
circuit).
The commissioning as well as
the servicing of the appliances
may only be carried out by per-
sonnel which are authorised by
OCHSNER.
The installation of the applianc-
es and their electrical wiring
may only be carried out by a
specialist according to local reg-
ulations and codes of practice.
Protective functions for the heat
pump can be activated by the
control. However, as the control
is not certified as a safety appli-
ance, the protection against
failure or damage to the heat
pump must be adapted to the
local instructions (for instance,
by additional external switching
of the safety appliances used.
The installation of the applianc-
es and their electrical wiring
may only be carried out by a
specialist according to local reg-
ulations and codes of practice.
OCHSNER accepts no liability for
possible damage due to im-
proper use.

4System operation
The heat pump operation takes place by
means of the basic operating panel. This
is easily accessible in a plastic housing
mounted on the heat pump. The user has
2 buttons and an illuminated display at
his disposal.
The heat pump has no separate
main switch. In emergencies, the
system must be switched off by
means of the specified circuit
breakers. The circuit breakers
must be so reachable as to en-
sure a switching off at any time.
4.1 Main display
Current temperatures and operational conditions are shown in the main display.
Fig. 5: Control unit MB64xx
Control using the control unit MB64xx in the heat pump's inside unit is described as fol-
lows. Separate operating instructions are available for the room control units and the
room terminal.

5Heating/Cooling (Heating circuits)
5.1 Room temperature too high, too low
With this function, the current room
temperature set value can be adapted for
individual requirements/circumstances
quickly and simply.
If, however, it is obvious that the room
temperature, especially at higher or low-
er outside temperatures does not comply
with your requirements, it is recom-
mended to adjust the heating/cooling
curve accordingly (see Section
5.8/5.10).
Settings procedure:
1. In the main display turn the button > the
comfort menu appears
2. Select the desired heating circuit in the com-
fort menu by turning and pressing the but-
ton.
3. The room temperature set value can be ad-
justed by turning the adjusting button.
4. The setting is stored by pressing ENTER.
5. By pressing of the ESC – button you return
to the main display.
Please observe: Any change in the room
temperature set value will automatically
shift the heating curve and change the
heating limit (the same holds for cooling
mode). Any change in the room tempera-
ture set value will also change the energy
consumption of your heat pump system.
5.2 Influence of room temperature
The set heating circuit flow temperature is always controlled according to the set heat-
ing/cooling curve (outside temperature dependent). If the system has a room control unit
or a room terminal with touch display (which can measure the current room temperature
in this heating circuit), the current room temperature can also be additionally used for
calculating the set flow temperature. If you wish to use this function, please contact your
OCHSNER system partner.

5.7 Adjusting the heating curve
For weather dependent heating controls, the current set flow temperature is deduced by
means of the current outside temperature. The heating curve is also used. The heating
curve is adjusted using 3 parameters. Heating starts only when the mean outside temper-
ature in the past 10 h (standard setting) is lower than the set heating limit (see Section 0)
Parameter Description
03-001 Base point temperature
heating curve
The desired flow temperature at 20°C outside tem-
perature is set here.
03-012 Design outside tempera-
ture
The standardised lowest outside temperature in the
climate region is set here.
03-013 Design supply tempera-
ture (VLT)
The desired flow temperature at standard outside
temperature is set here.
Fig. 8: Heating curve with setting parameters
If required, when the room temperature is too low or too high, the user can make small
adjustments to the heating curve by means of the following table. The basic settings for
the heating curve are to be carried out by a specialist engineer.
As changes to settings - due to the inertia of the heating system - only affect the room
temperature time-delayed, it is recommended to only carry out one adjustment step
per day.

5.9 Cooling curve
For weather dependent controls, the current set flow temperature is deduced by means
of the current outside temperature. The cooling curve is adjusted using 3 parameters.
Parameter Description
03-043 Cooling setpoint temper-
ature
The desired flow temperature at 20°C outside tem-
perature is set here.
03-047 Design outside tempera-
ture cooling curve
The standardised outside temperature in the cli-
mate region is set here.
03-048 Design supply tempera-
ture cooling curve
The desired flow temperature at standard outside
temperature is set here.
Fig. 10: Cooling curve with setting parameters
Dew point limit:
In the "cooling" mode, the minimum flow temperature is limited. The limit (dew point) is
calculated by the control using the following values:
•Current room temperature:
•Current relative humidity in the room
If no room temperature can be measured, the current outside temperature is used. If no
relative humidity can be measured, the dew point limit is calculated using a substitute
value of 60% rel. (Room temperature and humidity can be measured by the room control
units or by the room terminal with touch display).
Incorrect cooling curve settings can cause damage to the system (condense wa-
ter build up). OCHSNER accepts no liability for this! Change the cooling curve
settings only after consulting your contractual partner!
