Minimum and maximum temperature

The sensor records the minimum and maximum temperature.

These values can be examined or reset via the temperature controller (VMB1TC / VMB1TCW) or through the Velbus

link software via a PC connected to the Velbus PC interface (VMB1USB, VMB1RS of VMBRSUSB).

Differential thermostat

Using two sensors a differential thermostat can be created. When the difference in temperature between both sensors

reaches a certain value, the relay channel can be activated.

To achieve this, the first sensors must know the address of the second one. The second sensor must than be linked

to a relay channel. The temperature difference value is set on the first sensor.
