The passage automatically 3° cooler than the office
When the sensor module in the office is set to day-mode, the temperature in the passage must be 3° lower than the
office. Is the day temperature of the office is set to 20°C the desired passage temperature will be 17°C.
When the sensor module in the office is set to night-mode, the temperature in the passage must be 3° lower than the
office. Is the night temperature of the office is set to 15°C the desired passage temperature will be 12°C.
Configuration:
The easiest way to configure the system is to use the Velbus link program via a PC connected on the Velbus PC interface
(VMB1USB, VMB1RS of VMBRSUSB).
However, configuration can also be done without the aid of a computer. Refer to the procedure below.
Link the heating output of the office sensor to a relay channel (ex. channel1).
Use the relay channel (ex. channel1) to control the valve of the office radiator.
Link the heating output of the passage sensor to another relay channel (ex. channel2).
Use this relay channel (ex. Channel2) to control the valve of the passage radiator.
