and off.
FI = internal, built-in sensor.

show the zone number (1–16) for three
seconds.

When CFG is linked to CT- and the green
lamp is lit, the thermostat is being regulated
by CT-. When the lamp is dimmed, the
temperature may be regulated on the
thermostat using the and keys.

ing its own controls, the green reception

Using the and keys, you may set the
temperature as desired.
