Installing the mixed circuit with buffer
tank, DHW tank and external passive
cooling
(VWS only)

5.5.1

Description of functions for the heating
mode with buffer tank, DHW tank and
external passive cooling

The heating circuits are connected as a separating tank to
the heat pump via a buffer tank and are operated using an
external heating circuit pump via a heating circuit mixer.
By default, this is controlled by a flow temperature setpoint
control (

¬

Ch. 9.4.3

).

The VF2 flow temperature sensor sits behind the diverter
valve in the heating flow (because of the cooling function).
The heat pump responds to a demand for heat from the
buffer tank.
The heat pump also operates a DHW tank.

5.5.2 Installation

instructions

>

Install the hydraulic components in accordance with the
local requirements and as shown in the sample hydraulic
scheme below.

>

If you do not use the optional accessory heat pump brine
filling unit for heat pumps (

56

) (

¬

Fig. 5.6

), install the

individual hydraulic components accordingly (

¬

Fig. 5.9

).

Dimension and install an external cooling heat exchanger.

>

Connect a limit thermostat to ensure the underfloor
heating function on the heat pump.

>

Connect the VF2 flow temperature sensor to ensure the
integral energy function.

>

When starting up the unit, set Hydraulic Scheme No 10 in
the controller.

You can choose to use the VPS/2 multi storage tank as a
DHW tank.

>

When connecting the hydraulics, observe the

¬ installation instructions

for the cylinder and the

¬ geoTHERM planning information

.

The 1” diverter valve supplied in the VPS/2 multi storage
tank must be replaced by two 3-way diverter valves that
must be installed on-site. The diverter valves must be con-
nected to the LP/UV1 terminal on the controller PCB (

2

)

(

¬

Fig.

7.18

).

i

As of VWS/VWW 380/2, the VPS/2 1500 multi

storage tank must be used.

The following only applies when installing the optional
external passive cooling:

b

Caution!

Risk of malfunction in cooling mode.

The buffer tank must not be in operation
during the cooling mode of the heat pump.

>

Install a motor-driven 3-way diverter
valve in both the flow and return so that
the buffer tank is avoided in cooling
mode.

Caution: Schematic only!

These examples of hydraulic schemes do not contain all of
the shut-off and safety instruments that are required for
correct installation.

>

Observe the applicable standards and regulations.
