VELBUS CHARACTERISTICS
• 2-wire communication for Velbus data and 2 wires for power supply
• data transmission: 16.6 Kbit/s
• Serial data protocol: CAN (Controller Area Network)
• Short circuit proof (towards negative or positive pole of the power supply)
• LED indication when receiving or transmitting data over the Velbus
• bus error indication: 2 short flashes of the LEDs
• auto recovering after 25 seconds when a bus error occurs
The sensor module can be given a designation with a maximum of 16 characters.
The temperature sensor module
can transmit following messages
:
• output status
• manual pushbutton status
• sensor status
• sensor temperature, minimum and maximum temperature
• time statistics (heating/air-conditioning on time)
• sensor settings
• sensor configuration
• module type (including zone number and software version)
• sensor name
• memory content
• the communication error counter
The temperature sensor module can transmit following instructions:
• change the status of the LED(s) on the pushbutton module
• switching off the LED(s) on a pushbutton module
• switching on the LED(s) on a pushbutton module
• make LED(s) on a pushbutton module flash slowly
• make LED(s) on a pushbutton module flash fast
• the desired temperature for the linked sensor to create a differential thermostat
The temperature sensor module can receive following messages:
• the status of a pushbutton module
The temperature sensor module can receive following instructions
:
• to set:
the desired temperature
the desired comfort temperature for heating
the desired day temperature for heating
the desired night temperature for heating
the anti-freeze safeguard temperature
the heating limit
the desired comfort temperature for cooling
the desired day temperature for cooling
the desired night temperature for cooling
the lower limit of the cooling preset range
the upper limit of the cooling preset range
the hysteresis
calibration of the sensor
the temperature difference for fast heating/cooling or for the differential thermostat
the temperature difference for fast heating or cooling
the alarm temperatures
the default duration of temporary mode (sleep time)
the zone number
the address of the linked sensor to set up a differential thermostat
• to determine:
heating
