Programmable flush-mounted controller - Room thermostat VT D-UP

Programmable flush-mounted controller - Room thermostat VT D-UP – Vitramo – 4250939310084: Programmable flush-mounted controller VT D-UP version on/off, type of power supply 230 V AC, three-/four-wire connection, measuring range lower value 5°C, measuring range upper value 30°C, thermal feedback without, control characteristic PI, heating, number of outputs Heating 1, number of cooling outputs 0, differential value 0.5 ... 0.5K, temperature can be read, resistance sensor design, type of installation flush-mounted, with display, operation button, type contact closer, max. voltage of the contacts 230V, max Contact load 10A, protection class (IP) IP30, protection class (NEMA) other, color cream white, RAL number 9010, height 50mm, width 50mm, depth 46mm, temperature controller class I, power consumption in standby mode (solstandby) 0W, digital flush-mounted room thermostat Can be used separately as an independent device or in almost all flat switch systems using intermediate rings in accordance with DIN 49075. With an intermediate frame, which you can obtain from your switch manufacturer, you can easily integrate the room thermostat into an existing light switch system! A standard frame is included in the scope of delivery if you do not want to integrate the room thermostat into an existing switch system. The controller uses an internal sensor to measure the room temperature and closes the heating contact if the temperature falls below the setpoint. The symbol signals the active heating phase. The digital weekly timer has 3 programs for switching between comfort and reduced temperature. The controller is already preset to normal daily routines. Settings are saved permanently. The reset button resets to the factory settings. Temperature setting in 0.5 K increments. Sensor tolerance: ± 0.5 K. Switching difference: approx. 1 K. Power consumption: approx. 1 W. Heating contact: normally open, max. 230 V 8(1)A. Night reduction: normally open contact max. 230 V 10 mA. Internal sensor: NTC 47. Protection class: II after appropriate installation. Ambient temperature: 0...30°C. Storage temperature: -20...+70°C. Radio interference suppression: according to EN 50081-1, EN 50082-1. Power reserve: 4 days after 1 hour of operation. Valve protection: 5 min a/week. with assembly instructions in original packaging. In order to optimally plan the Vitramo heating system, it is not only designed according to DIN EN 12831, but also adapted to the special conditions of the building. Already during the planning phase, a building is divided into rooms, demand zones and heating areas depending on its size and use. A demand zone represents a space/space defined by its specific type of use and conditions such as cooling, ventilation, humidity, etc. Every room needs a room thermostat to regulate the air temperature. Wire-guided room thermostats as room temperature controllers are wired directly to a heating element. Due to the structural conditions, these devices are often used in new buildings or as part of a renovation. If the installed power exceeds the specified switching capacity of the respective room thermostat, then the heating elements must be switched via additional load relays type LS-E. In any case, the life of the room thermostat will be extended if a load relay does the work.
