E.g. Number rings for answering machine is 4.
Number rings for the CEM-24 is 5.
Follow these steps:
1. Set the ring setting to 6 rings (see below).
2. Call the CEM-24.
3. Let the telephone ring 3 times and hang up.
4. Wait for 4-5 seconds, and call again
5. The CEM-24 will answer after the second ring on the second call, before any other
device.
To set the number of rings for the CEM-24:
• Press the Select button again – "Fn 02" will be displayed.
This is the set number of rings after which the CEM-24 should answer. For the
example above, FN should be set to 05.
If no device other than the thermostat is connected to the phone line, then the number
of set rings for the CEM-24 should be at least 6.
This will ensure that the user has time to answer the telephone before the call is
answered by the thermostat.
