The PRE9700 is a 230V supply and 12V switched window switch disconnect unit.
The PRE9700 is designed to be used in conjunction with any of the prefect controls range of heating products. When connected to an appropriate window switch (not supplied) the unit will disconnect the supply to the connected load when the switch contacts are opened.
The unit is supplied by 230V AC from the controlling thermostat. The unit supplies a 12V supply feed to an appropriate switch. When the 12V circuit is closed the relay will be closed powering the heating system, when the circuit is open i.e. the window is open the relay will open disconnecting the supply to the heater or radiator until the window is closed.
The PRE9700 can also control 'wet' systems that are not using ecostat2 or Irus but, have a mains driven control valve.
