thermio™ essential H rf

PRODUCT DESCRIPTION

The thermio™ essential H rf is a digital room thermostat of ErP class I. Its wireless radio technology allows it to be placed anywhere in the room without laying electrical cables and thereby enables extremely convenient control and monitoring of the room temperature. Its integrated frost protection function is activated automatically as soon as ambient temperatures drop below the saved temperature setpoint. Up to 16 receivers can be connected to the transmitter. In case of poor radio communication, manual operation is possible using an ON/OFF switch. An additional mounting plate not only enables quick and easy on-wall mounting, but also contributes towards an elegant appearance.

BENEFITS

  • The wireless radio technology allows individual placement in rooms without laying electric cables
  • Signalling and control accuracy ensured through high frequency radio signal range of up to 30 metres inside buildings
  • Long battery life through efficient energy management
  • Monitoring the battery status and display with the required battery change
  • The frost protection function prevents the freezing of radiators or icing of piping, even when switched OFF
  • Cost reduction and efficient energy management through high level of control accuracy
  • Very easy and convenient to use through large LC display, manual ON/OFF switch and reset button
  • High fexibility – up to 16 receivers can be connected to the device
  • Increased comfort through a wide temperature control range of +5°C to +35 °C
  • Fast, simple and safe installation through surface mounting
