DESCRIPTION

The sensor module can be used to measure and send temperatures over the Velbus-system. In combinatio n with a relay module (VMB4RYNO / VMB4RYLD or VMB1RY) a thermostat can be set-up to control a heating or cooling installation. Setting the comfort, day, night or anti-freeze mode can be done via the local pushbutton of with pushbuttons that are connected to the Velbus. Different sensors can be configured and controlled from a remote location through a temperature controller (VMB1TC / VMB1TCW) or via a PC interface (VMB1USB, VMB1RS or VMBRSUSB) and the Velbus link software. The temperature controller (VMB1TC / VMB1TCW) can also include program instructions to control different sensors.

CHARACTERISTICS

 Temperature range of the sensor: -10° to 63.5°C (14° to 146°F)  precision after calibration:

 ±0.5°C at 25°C  ±1°C between -10°C and 63.5°C

 Resolution: 0.0625°C  Hysteresis: 0°C to 15.5°C (interval of 0.5°C)  Possibility to automatically send the ambient temperature over the Velbus  Registration of minimum and maximum temperature  Registration on-time of heater/air-conditioner  Thermostat function for cooling or heating  In combination with a second sensor a differential thermostat can be created  Range:

 heating function: -32°C to 54°C in steps of 0.5°C (default settings: 5° to 30°)  cooling function: -32°C to 54°C in steps of 0.5°C (default settings: 16° to 36°C)

 Relay steering via Velbus for:

 heating  fast heating/cooling  heating boiler in day mode  cooling  steering circulation pump  alarm at low temperature  alarm at high temperature

 Cycling protection delay on heating and cooling outputs (minimum on/off switching delay): 1 minute defaul t (can be

switched off or set in multiples of minutes via Velbuslink software)

 Selectable unjamming function for the circulation pump and/or heating valves (min. 1 minute/day on)  Control:

 local pushbutton  remotely via pushbuttons connected to the Velbus  via temperature controller VMB1TC / VMB1TCW  through Velbus program instructions

 Local control for switching between:

 comfort mode  day mode  night mode  safeguard mode (anti-freeze)

 Possibility to prevent (lock) local control  Control through pushbuttons connected to the Velbus to:

 set the module to comfort temperature  set the module to day temperature  set the module to night temperature  set the module to safeguard temperature (anti-freeze)  set the thermostat to heating  set the thermostat to cooling  lock the local control  unlock the local control

 Heating can be set in anti freeze mode through window contacts conne cted to the Velbus when a window is opened  Feedback to the pushbutton modules to update the LED status

Can be programmed without the aid of a PC

  Simple learning process by pressing the desired pushbuttons while in learning mode

 Storage capacity of 10 different pushbuttons per control function  LED indications for:

 thermostat function for cooling  comfort mode  day mode  night mode  heater/air-conditioning status  power supply voltage  receiving/transmitting data over the Velbus

 Settings for:

 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 (upper limit of the heating preset range)  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 low temperature alarm (alarm when temperature drops below this value)  the high temperature alarm (alarm when temperature rises above this value)  the duration of temporary mode: from 1 to 65.279 minutes (45 days, 7 hours, 59 minutes)  transmitting the current temperature over the Velbus:

o only when requested o only when changes occur o at specific time intervals, selectable between 10 and 255 seconds (4 minutes 15 seconds)

 resetting minimum and maximum temperature  the zone (each sensor can belong to a specific zone)  the address of the linked sensor to set up a differential thermostat  cycling protection delay (minimum on/off switching delay)

 Change settings through Velbus instructions or via a temperature controller (VMB1TC / VMB1TCW)  Control through a program stored in a temperature controller (VMB1TC / VMB1TCW)  Different modes:

 automatic: the sensor module accept all program instructions  temporary manual: program instructions are ignored during a specific period of time  manual: all program instructions are ignored and local control is locked

 The learned pushbutton functions and settings are retained when voltage drop-outs occu r  246 possible addresses (setting via rotary switches)  Required power supply: 12 to 18VDC  Consumption when not in use: 12mA

Maximal consumption: 15mA



Dimensions (W x H x D): 43 x 46 x 22mm

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

EMBEDDING THE TEMPERATURE SENSOR

The temperature sensor VMB1TSW can be embedded in combination with blank frames VMBFBI and cover plate. It is possible to use a 2- or 3-module wide frame with cover plate from the BTicino Living series. The module must be pushed into the build-in frame from the front.

It is also possible to use a 3-module wide frame with cover plate from the BTicino Light or Light Tech series. The module must be pushed into the build-in frame from the front.

To build the sensor in into a hollow wall, use a hollow wall pattress.
