for Control Center VR 65

4 Installation

The Control Center can be wall-mounted near to the 
DHW cylinder. The hot water and heating programs as 
well as all required parameters are set at the VRT 360 
or VRC 400. All heating circuit connections are made at 
the Control Center using a ProE plug.

timeSWITCH 140

Digital 2-channel timer with daily/weekly program for 
heating and hot water.
The timeSWITCH 140 can be plugged into the Vaillant 
ecoTEC boiler.
There are three individually programmable time win-
dows per day for heating and hot water. The timer can 
be set to run a weekly or a daily program.
By activating the calendar function, an automatic 
summer/winter changeover is activated.

VRT 360

Digital room temperature thermostat with daily/weekly 
program for time and temperature control of heating 
and hot water.
Designed for wall mounting. 
There are three individually programmable time win-
dows per day for heating, hot water and a hot water 
circulation pump. Different target room temperatures 
can be set for each time window.
The thermostat can be set to run a weekly or a daily 
program.
By activating the calendar function, an automatic 
summer/winter changeover is activated.

VRC 400

Digital weather-dependent control with daily/weekly 
program for time and temperature control of heating 
and hot water.
Designed to plug into the Vaillant ecoTEC boiler or for 
wall mounting.

  Set the heating curve to adjust the flow temperature 

to suit the heat requirement of the building. Optimises 
the flow temperature to the prevailing weather condi-
tions.
There are three individually programmable time win-
dows per day for heating, hot water and a hot water 
circulation pump. Different target room temperatures 
can be set for each time window.
The control can be set to run a weekly program or a 
daily program.
By activating the calendar function, an automatic sum-
mer/winter changeover is activated.

 Caution!

Do not use a VRT 360 or VRC 400 in combina-

mostat e.g. VRT 30 due to the impact this may 
have on the operation of the VRT 360 or VRC 
400.
