VMB1TS manual – edition 2 3
DESCRIPTION
The sensor module can be used to measure and send temperatures over the Velbus-system. In combination with a
relay module (VMB4RY 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) or via a PC interface (VMB1USB, VMB1RS or VMBRSUSB) and the Velbus link
software.
The temperature controller (VMB1TC) 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 default (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
• 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 connected 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
