ELKO EP TER-13/2 Digital Thermostat

ELKO EP TER-13/2 Digital Thermostat is a switching control based on measured temperature with a built-in time switch (Wi-Fi®) that allows daily, weekly, and yearly programs. This digital thermostat is subordinate to the time-switch programs and provides complex control of home and water heating. The TER-13/2 digital thermostat includes two thermostats in one, two temperature inputs, and a 2-channel design (each with an operating hours counter). This digital thermostat supports time synchronization via an NTP server (requires an internet connection on the thermostat) and features a built-in web server for setup and control via Wi-Fi. Functions include two independent single-stage thermostats, a differential thermostat, a two-stage thermostat, a thermostat with a “WINDOW” function, and a thermostat with a dead zone.

The TER-13/2 digital thermostat operates at 1.2W maximum power dissipation, 250VAC/30VDC switching voltage, 1s minimum switching interval, and ±0.5s day (23°C) maximum accuracy. This digital thermostat provides A1-A2 supply terminals, DIN rail EN 60715 mounting, and IP40 front panel/IP20 terminals protection degree.

Features

  • Switching control based on measured temperature with a built-in time switch, allowing daily, weekly, and yearly programs, making the thermostat function can be limited in real-time as needed
  • The thermostat is subordinate to the time switch programs
  • Simple setting after the first start-up
  • Complex control of home and water heating, incl. solar heating
  • Two thermostats in one, two temperature inputs, 2-channel design (each with an operating hours counter)
  • Two independent single-stage thermostats, depending on the functions of two thermostats, a differential thermostat, a two-stage thermostat, a thermostat with a “WINDOW” function, and a thermostat with a dead zone
  • Wide operating temperature settings -40°C to +120°C, that can be changed in real-time
  • A user-replaceable battery to back up the set time during power outages
  • Built-in web server for setup and control via Wi-Fi® connection
  • Time synchronization through an NTP server (requires an internet connection for the thermostat)
  • Possibility of permanent connection to the local network
  • Web Remote Control (WRC) and setup from anywhere (requires an internet connection to the thermostat)
  • New well-arranged display with white backlight
  • Pulse/cycle output mode
