3 Description of the room
thermostat
The VRT 360 is a programmable room
thermostat with a weekly programme for
heating, hot water and a circulation
pump for connecting to Vaillant boilers
with an eBus.
The VRT 360 enables you to set the
room temperature using heating pro-
grammes. In addition, you can select
special functions (such as the party
function), and control the timed opera-
tion of hot water and a separate circula-
tion pump.
4 Operation
The operating principle uses three but-
tons and a dial (Vaillant “Turn and Click”
operating concept).
The display normally shows the current
operating mode (e.g. ), or, if activat-
ed, the special function and the current
room temperature, the day of the week,
the time and the symbol for heating, hot
water and/or the circulation pump,
depending on which is requested.

mal display mode, press the dial once –
the symbol for the selected mode
flashes in the display.
