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 VMB4RY) 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. For this, on
the relay module the TIME1 and MODE/TIME2 rotary switches of the channel must be set to position ‘0’.
The easiest 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).
However, it can be done without the use of a computer as described in the following procedures.
