Velleman VMB1TSW - Manual (Page 4)

 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 occur
 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
