SETTINGS
Following parameters can be set via the temperature controller (see manual VMB1TC / VMB1TCW(W)) or via the
Velbus link software:
the zone to which the sensor belongs
the operating mode (heating or cooling)
switching the unjam function of the circulation pump and/or heating valve on or off
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 temperature difference for fast heating/cooling or for the differential thermostat
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 alarm temperatures
the duration of temporary mode
the zone number
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
reset time registration for the heater/air-conditioning
locking or unlocking local control
the address of the linked sensor to set up a differential thermostat
sensor name (max. 16 characters)
The cycling protection delay (delay setting is 1 minute) can be modified through the Velbuslink software if the
software version of the sensor module is 0949 or higher (see “Verify software version”).
Preset range
The preset range for the desired temperature can be adjusted by the user.
This is a way to make sure that the heating can never be set higher than a certain value.
Protecting the circulation pump and/or heating valves
When a circulation pump or a valve is not being used for some time, it might get stuck. To avoid this, an unjamming
function can be enabled which activates the pump or opens the valve for at least one minute every day.
Enabling of disabling the unjam function can be done via the temperature controller (VMB1TC / VMB1TCW) or
through the Velbus link software via a PC connected to the Velbus PC interface (VMB1USB, VMB1RS of
VMBRSUSB).
Time statistics
For every mode (comfort, day, night or anti-freeze) the time during which the heating or air-conditioning was one is
stored. These statistics can be recalled or reset via the temperature controller (VMB1TC / VMB1TCW) or through the
Velbus link software via a PC connected to the Velbus PC interface (VMB1USB, VMB1RS of VMBRSUSB).
