Mixing module
The mixing module has been designed for operation connected to Buderus heat pumps in conjunction with the
HMC 10 control unit; Logatherm WPS 22...60. It has an
XB2 board which is used to control an additional mixed
circuit.
A maximum of three mixing modules can be used per heat
pump with the Logatherm WPS 22...60. PKSET does not
count as a mixed additional circuit. This means that three
mixing modules can be used if PKSET is used.
Units that are connected to a mixing module are displayed
and can also be adjusted at the control panel for the heat
pump.The mixing module can also be used to control a
pool with the Logatherm WPS 22...60. If a mixing module
is used for controlling a pool, only two mixing modules can
be used to control additional circuits.
The mixing valve is closed completely once a day for 3-5
minutes to calibrate the function. No heat is supplied to
the heating circuits for this time.
When an air handling unit (Program Version 2.0) is
installed in the circuit, a different calibration method is
used to prevent freezing of the heating battery.
The settings for circuit 3-4 are described under Settings in the Logatherm WPS installation manual.
The settings for the cooling system are described under Settings in the PKSET installation instructions.
In addition to the mixing module, an additional mixed circuit must also be equipped with a mixing valve, circulation
pump, flow temperature sensor and possibly a room temperature sensor.
Circuit 1 must always be installed and used.
The task of the heat pump is to keep circuit 1
at the correct temperature in accordance
with the heat curve. The flow temperature in
circuit 2-4 cannot be higher than the value of
circuit 1. This means that an underfloor heating system in circuit 1 cannot be combined
with radiators in another circuit.
Under certain conditions, a room temperature reduction in circuit 1 may affect the other
circuits.
When the Use temperature from circuit
with highest temperature function under
Circuit 1 is used, the heat curve for Circuit
1 does not need to be adapted to the mixed
circuits. The heat pump automatically selects
the highest flow temperature set point value.
The mixing valve is controlled via PID regulation in order
to achieve the required flow temperatures. To allow the
mixing valve control system to operate properly, it is crucial to set the correct mixing valve running time in the
menu for the relevant heating circuit. The mixing valve running time is normally specified on the mixing valve. For
more information, refer to Settings in the installation manual for the heat pump.

Installation
6.1
CAN-BUS
The various circuit boards in the heat pump are joined by
a communications cable, CAN-BUS. CAN (Controller
Area Network) is a two-wire system for communication
between microprocessor based modules/circuit boards.
CAUTION: Interference.
B The CAN-BUS cable must be screened
and laid separately from the power cable.
Suitable cable for external laying is cable LIYCY (TP)
2x2x0.5. The cable must be twisted pair and screened.
The screen must only be earthed at one end and to the
chassis.
Maximum cable length is 30 m.
CAN-BUS cable must not be laid alongside power supply cables. Minimum distance 100 mm. They may be laid
alongside sensor cables.
CAN-BUS
6
CAUTION: Do not mix up the 12V and CANBUS connections!
The processors are destroyed if 12V is connected to the CAN-BUS.
B Check that the four cables are connected
to the contacts with the corresponding
marking on the circuit board.
The connection between the circuit boards is by four
wires, because the 12V-supply between the circuit
boards must also be connected. The circuit boards have
markings for both the 12V and CAN-BUS connections.
Switch Term is used to mark the start and end of a CANBUS loop. Ensure that the correct circuit board is terminated and that all other switches are in the opposite position.

Handling circuit boards
Circuit boards with control electronics are sensitive to
discharges of static electricity (ESD – ElectroStatic Discharge) when handled. To prevent damaging the components, special care is therefore required when handled.
CAUTION: Never grasp a circuit board without wearing a ground-connected bracelet.
A condition for good ESD protection is a ground-connected bracelet when handling electronics. This bracelet
must be put on before opening the screened metal bag/
packaging or before exposing an installed board. The
bracelet must be worn until the circuit board is enclosed
in its screen packaging or closed electric box. Replaced,
returned circuit boards must be handled in the same way.
6 720 614 366-24.1I
Fig. 8
Bracelet
Damage is usually latent, and a circuit board can operate
impeccably during commissioning but show signs of
problems later. Charged objects may only be problematic
if they are in close proximity to the electronics. Keep a distance of at least one metre from expanded polystyrene,
protective plastic and other packaging, synthetic material
(e.g. fleeces) and similar before starting work.

the address selection of additional mixed circuit 2 must
be set to 2 (circuit E14). If more mixing modules are
added, make sure that with each additional module
switch A is numbered consecutively in accordance
with the heating circuits. The program selection for the
additional mixed circuit 1 and 2 must be set to 0.
The settings for the cooling system are described in the PKSET installation manual.
6.3.2
B Fasten the mixing module to the wall near the heat
pump. Mount the unit at the four corners with screws.
B Establish the electrical connections once the unit has
been fastened to the wall.
B Screw down the cover of the mixing module on the unit.
6.4.1
Room sensor T5 (accessory)
It is only the room where the room sensor is
located that can influence regulation of the
temperature for the relevant heating circuit.
Installation location requirements:
• If possible, interior wall without drafts or heat radiation.
• Unimpeded circulation of room air under room sensor
T5 (dotted area in figure 13 must be kept clear).

closed to a fully open mixing valve (the mixing
valve stops sounding and the endposition
switch switches off).

B Set the number of minutes for manual operation.
Different vital components can be put into operation/
turned off separately.
With 0min, status, e.g., On or Off, is displayed for each
component.
With the pool control system, it is essential
that the mixing valve (E81.Q81) opens and
closes in the right direction towards the heating system. When the mixing valve is fully
open, the entire flow is directed to the heating system. When the mixing valve is fully
closed, the entire flow is directed to the pool
exchanger.
