Primary heating circuit control system

The primary heating circuit can be controlled in one 
of the following ways:

Vaillant dual-channel eBUS controller with  Vaillant 
Control Centre (connection wiring diagrams 1 and 2, 
¬ section 6.8)

Important:

 

Terminals 

NTC

 and 

CYL.

 of the  Vaillant Control Centre 

may not be connected at the same time.

 

– Option 1: The upper cylinder sensor 

NTC

 is connected to 

terminal 

NTC

 of the  Vaillant Control Centre.

The recharging of the cylinder is controlled via the eBUS 
controller. Here, the cylinder temperature is measured 
using the cylinder sensor 

NTC

. The temperature is com-

pared with the target value programmed in the eBUS 
controller and the cylinder is reheated if necessary.

 

– Option 2: The cylinder thermostat is connected 

up to terminal 

CYL.

 of the  Vaillant Control Centre.

The recharging of the cylinder is triggered via the cylin-
der thermostat. If the actual value falls below the target 
temperature set on the cylinder thermostat, the cylinder 
thermostat is shut. The closing of the cylinder thermo-
stat is registered by the  Vaillant Control Centre and 
passed onto the eBUS controller. 
The eBUS controller releases the recharging of the 
cylinder for the programmed primary heating times: 
The primary heating device activates and the  Vaillant 
Control Centre switches the zone valves into the correct 
position for the recharging of the cylinder.
The required zone valve position differs depending 
on whether the S plan is being used: 

 

– S plan: Valve 

CH

 closed, valve 

DHW

 open.

VRS 560/2 
(connection wiring diagrams 3 and 4, ¬

 

section 6.8)

The upper cylinder sensor is connected to the terminal 

SP 1

 of the VRS 560/2.

The output EP of the VRS 560/2 is connected to the 
input 

CYL.

 of the  Vaillant Control Centre.

The recharging of the cylinder is controlled via the 
VRS 560/2. Here, the sensor 

SP 1

 measures the cylinder 

temperature. The temperature is compared with the pro-
grammed target value in the VRS 560/2.
Within the primary heating times programmed in the 
VRS 560/2, the contact 

EP

 is closed if the actual value 

falls below the target temperature for the cylinder.
The closing of the contact 

EP

 is registered by the 

 Vaillant Control Centre and the recharging of the cylin-
der is triggered: The primary heating device activates 
and the  Vaillant Control Centre switches the zone valves 
into the correct position for the recharging of the cylin-
der. 
The required zone valve position differs depending 
on whether the S plan is being used: 

 

– S plan: Valve 

CH

 closed, valve 

DHW

 open.

Vaillant dual-channel eBUS controller with VR 68/2 
(connection wiring diagram 5, ¬

 

section 6.8)

The upper cylinder sensor is connected to the terminal 

SP 1

 of the VR 68/2.

The recharging of the cylinder is controlled via the eBUS 
controller, which is connected with the VR 68/2 and 
VR 61/2 via eBUS. The zone valves are switched via the 
VR 61/2 (valve DHW open, heating circuit valve closed).

VRS 560/2 in conjunction with non-eBUS-compatible 
controllers (connection wiring diagram 6, ¬

 

section 6.8)

The upper cylinder sensor is connected to the terminal 

SP 1

 of the VRS 560/2.

The output 

EP

 of the VRS 560/2 is connected to the 

wiring of the S plan via the cylinder thermostat. 

Important:

 

The target temperature on the cylinder thermostat must 
be set to the maximum temperature!

The recharging of the cylinder is controlled via the 
VRS 560/2. Here, the sensor 

SP 1

 measures the cylinder 

temperature. The temperature is compared with the pro-
grammed target value in the VRS 560/2.
Within the primary heating times programmed in the 
VRS 560/2, the contact 

EP

 is closed if the actual value 

falls below the target temperature for the cylinder.
The switching signal is coupled into an S plan and the 
recharging of the cylinder is triggered.

Room heating control

The room heating can be controlled in one of the follow-
ing ways:

Vaillant dual-channel eBUS controller with  Vaillant 
Control Centre (connection wiring diagrams 1, 2, 3, 
and 4, ¬

 

section 6.8)

The room heating is controlled by the Vaillant 
eBUS controller.
The actuation of the valves (S plan plan) 
is controlled by the  Vaillant Control Centre.

Vaillant dual-channel eBUS controller with VR 61/2 
(connection wiring diagram 5, ¬

 

section 6.8)

The room heating is controlled by the Vaillant eBUS 
controller.
The actuation of the valves (S plan plan) is controlled by 
the VR 61/2.

Programmable timer and room thermostat 
(connection wiring diagram 6, ¬

 

section 6.8)

The room heating is controlled using a programmable 
timer and a room thermostat.
The actuation of the valves (S plan) is realised 
via the programmable timer and DHW timer.
