Wireless

  • consists of a receiver and transmitter
  • requires 2 AA batteries to feed a transmitter
    • typical battery life is 2 years
  •  Temp. range: 5°-30°C
  • 30m straight line transmitter range
  • needs 4 wires to wire up: 240V live, neutral, common, switch-live
  • TRV is not necessary within the same room as the room thermostat
  • a wireless thermostat is far easier to install and offers more flexibility
  • We recommend Danfoss RX1
  • Mechanical thermostat:
    • works much like a normal mercury based thermometer
    • can often maintain temperatures that are often 1°C higher than the set-point, which can inadvertently use up to 10% more energy
    • slower to respond to temperature changes
  • Programmable room thermostats:
    • allows different temperatures to be set for different periods throughout the day, night or even week
