these instructions. This declaration shall be deemed void in the
event of a modification that has not been agreed with us.
2.2 Identification of notes in the operating instructions
General hazard symbol
Warning! Danger of personal injury!
Observe the relevant accident
prevention regulations.
Warning! Danger from electrical vol-
tage! Prevent hazards arising from
electrical energy. Observe the instructi-
ons in local or general regulations (e.g.
IEC, VDE, etc.), and those of the local
energy supplier.

with the current national accident prevention regulations.
Should the system operator also have their own internal regu-
lations, these must also be observed.
2.6 Safety instructions for the operator
• Any existing touch guard protecting moving parts may be
neither removed nor shut down while the system is in opera-
tion.
• In the event of a fluid leak, any fluids must be collected or di-
verted in a way that prevents hazards to persons and the en-
vironment from arising.
• Prevent hazards arising from electrical energy.

Operating instrutions
WITA Fixed Setpoint Controller SM WR FR
• Observe the instructions in local or general
regulations (e.g. IEC, VDE, etc.), and those of the
local energy supplier.
• In the event of hazards arising from the system due to
contact with hot or cold parts, these parts must be fitted
with a touch guard.
• Keep flammable substances away from the product.
2.7 Safety instructions for installation and maintenance work
The system operator is responsible for ensuring that all instal-
lation and maintenance work is carried out by qualified per-
sonnel. These persons must also have familiarised themselves
in advance with the product using the operating instructions.
Conducting work on the pump is only permitted when the sys-
tem is shut down.
Ensure that the device is securely disconnected from the
power supply. Disconnect the device plug to achieve this.
Prescribed instructions for shutting down the device can be
found in the operating instructions. All protective mechanisms,
such as a touch guard, must be correctly reattached after
work.
2.8 Unauthorised conversion and production of spare parts
Modification or conversion of the product is only permitted
after prior consultation with the manufacturer. Only use origi-
nal spare parts for repairs. Only use accessories that have been
approved by the manufacturer. The manufacturer shall bear no
25

Operating instrutions
WITA Fixed Setpoint Controller SM WR FR
liability for any consequences resulting from the use of other
parts.
2.9 Unpermitted operation
If the pump is disconnected from the power supply, wait at
least 1 minute before reactivating. Otherwise, the pump's in-
rush current limit has no eect, which can lead to functional
errors or damage to any connected heating controller.
The pump's operational safety can only be ensured if it is used
as intended. Please observe section 4 of these
operating instructions here. Ensure compliance with
the limit values detailed in the technical data.
3 Transport and Storage
After receiving the product, inspect it immediately for damage caused in transport.
Should you detect any transport damage, assert a claim with the haulier.
Incorrect transport and storage can lead to personal injury or damage to the product.
• Protect the product against frost, moisture and damage during transport
and storage.
• Only carry the pump by the pump housing, and never by the connection
cable or terminal box.
• If the packaging weakens due to moisture, this can lead to the pump falling out
and causing severe injury.

on heating mixer
6.1 Mounting the fixed setpoint controller SM WR FR to dierent mixers can only be made
with manufacturer-specific mounting kits.
When selecting the drive, please observe because of the torque the data sheet of the
mixer while mounting with manufacturer-specific mounting kits, the enclosed installation
instructions has to be observed!
The drive is equipped with a special mounting
flange. By pressing the assembly / disassembly
button, a simple, tool-free installation of the fixed-
value controller on the mixer or the valve or disas-
sembly is possible.

6.2 Electrical installation
Due to the preassembled main connection cable and the preassembled
temperature sensor the SM WR FR is immediately ready for operation.
The temperature sensor was installed for flow temperature control at the flow line of the
heating or cooling circuit. For the return temperature control the sensor is installed at the
return of the boiler.
7 Safety instructions before and for commissioning
7.1 In the case of visible damage of the package or the product is it not to use.
The installation of a damaged product can be life threatening!
Observe the correct opening direction of the mixer or valve for controller
settings. Turning directions can carry out to high or too low temperatures in the system.
Minimum and maximum setpoint temperatures must be set correctly. Incorrect selected li-
mits may cause undesired temperature settings and – consequently - unwanted operation
which may damage the system. Every system, in which the controller is integrated, must
have independent system protection for too low or too high temperatures.
The controller has no protection function if the temperature in the system are too low or
too high.
7.2 Selection and setting of the applications, set temperature and mixer (valve) direction of
rotation.
The selection of the settings "application", "setting temperature" or "direction of rotation"
can be preset or carried out during commissioning.
7.2.1 Selection of the heating or cooling application
After confirming, the controller continues working with the changed setting!

8 Commissioning of the WITA Fixed Setpoint
Controller SM WR FR
When the controller is connected to the mains for the first time, the display shows the type of
the controller, the program version and the LOGO are displayed.
The display then changes to the base display. The base display shows at the first Commissioning
the factory setting, then the last set values and the Settings.
To make new settings with the controller the hand adjustment knob must be disassembled, so
that the adjustment buttons are accessible.
By simultaneously pressing the buttons (5s).
If the display changes to selection mode, it can be adapted to the existing system (see proce-
dure)
Mit Confirmation of the display will save the settings.
