Description of product

Properties BPT37:

The new system autodidactic of codes provides free operation and high resistance to interference. Large clear display informs you about each state, which takes place in the thermostat. It can be used to control gas or oil boilers, pumps, termoelectric drives, convector electric elements or to control air-conditioning. The wireless option allows for easy and quick installation, no such labor-intensive and lengthy installation of lines between the thermostat and the boiler to pass through the floor.

Advantages BPT37:

  • Backlight DISPLAY
  • thermostat can be displaced
  • Anticipating system (intelligent timer) guarantees set temperature in required time. Adaptive regulator evaluates temperature gradient of the room and is able to determine the time period necessary for the achieving of required temperature.
  • possibility setting of hysteresis (from 0,1°C to 1,5°C).
  • The possibility of setting PI control, which guarantees the temperature rise and its subsequent maintenance, the optimal energy consumption
  • memory E-EPROM store all data indefinitely even when power failure.
  • power of receiver is 230 V / 50 Hz.
  • receiver has the built in socket (for other electrical appliances).
  • color LED on the receiver.
  • range about  35 m in the built-up area, in an open area up to 300 m .
  • 9 weekly programms (optional).
  • easy controlling and programing
  • programme PARTY (short-term change of temperature). 
  • easy installation for standard boxes KU/KP68.
  • economy programme HOLIDAY(for max.99 days)
  • low power consumption.
  • COPY day.
  • Information about the operating hours of boiler.
  • regulation by 0,5°C.
  • TEST of right connection
  • Automatic indication of maintenance of the boiler
