Description of relay unit (CO-e)
1. Main switch (0/1).
Plug for wall socket
acts as main switch.
2. Function key.
The function key “F” has
several uses:
• To link up the relay unit to your CT- re

mote control. See the section on linking
up.
• To make CO-e receive commands from
the CT- remote control or not.
3. Lamp for radio reception.
When CO-e is
linked to CT- and the green lamp is lit, the
unit is being regulated by CT-.

If you wish to regulate

the key, CO-e may now be switched on
and off.

zone may be controlled by pressing in the

8 flashes = relay zone 24
8. Central locking.
If the relay unit’s lamps
are both flashing (both lamps flash for
appr. five seconds), the unit is locked at
