The relay box will normally be found mounted close to the boiler.

The green LED indicates normal operation of the radio frequency
system. When the green LED is ON the boiler is also ON. When the
LED is OFF the boiler is OFF.

You should use the push button to control your boiler only when the RF
communication is lost (see the

 

CM61NG Trouble-Shooting Guide).

The ATS module picks up a daily time signal from a transmitter in
Central Europe and corrects the time on the 

CM61NG display. So:

•

You never need to set or adjust the time

•

There is no need to adjust the unit by -/+ 1 hour in summer / winter
since the unit does this automatically

•

Your 

CM61NG is the most accurate clock in your home so you

can use this information to set-up all your other clocks.

* Not available in all Geographic Regions depending on transmitter
range and home location.

If you do not want to mount the room unit on the wall you can use
optional table stand, ask you installer for details

*Note: The room unit must be located in a location where reliable
communication was proven. Advise your installer where you would like
to position the room unit and they will check if the RF communication
is reliable in the selected location(s)
