CONFIGURING THE OUTPUTS
The sensor module transmit messages over the Velbus when the status of one of its multiple outputs changes. Relay
modules (VMB1RY or VMB4RYNO / VMB4RYLD) can be linked to these Velbus messages to perform following
functions:
 steering the heating valve
 switching the heating or cooling installation to boost mode when the difference in desired and current temperature
is too big
 set the heating boiler in day mode
 steering the air-conditioning
 steering the circulation pump of the heating installation
 generate an alarm when the temperature is too low (heating system down)
 generate an alarm when the temperature is too high (a valve does not close anymore)
Every relay channel that is steered by a temperature sensor must be set to momentary (instant) control.
The way to allocate those relay channels is through the use of the Velbus link software via a PC connected to a
Velbus PC interface (VMB1USB, VMB1RS of VMBRSUSB).
