1. Main switch (0/1).

The function key has several uses:
• To link up the thermostat to the CT- re

up.
• To make the thermostat receive signals
from CT-, or not.

show the zone number (1–16).

When the green lamp is lit, the thermostat
is being regulated by CT-. When the lamp
is dimmed, the temperature can be regu-
lated using the and keys.
4. Regulating temperature locally.
If you wish to override CT- and set the
temperature by means of the thermostat’s

temperature may now be set using the
and keys, as desired.

if the heater must work about 50% of the
time to maintain the temperature, the lamp
will be on for about 20 seconds and off for
20 seconds.
