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 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).
The configuration is now finished and the differential thermostat is enabled.
Remarks:
 Make sure both sensors are in heating mode (frost flower LED on the sensor is off).
 The passage temperature can never be higher than the preferred setting of its selected mode (anti-freeze, night,
day or comfort).
