2. Switching by telephone
It is possible to switch the status of the exit
relay (and thus the type of operation at the
connected regulator/thermostat) either by
telephone or by pressing the key ”manual
switching“ on the TFS.
In both cases, an LED below the key shows
that the TFS is in the ”heating“ mode (the relay
contact is closed).
Default setting is that the TFS accepts a call
after 4 rings and expects the access code
"1234". These settings can be altered, see 2.4
and 2.5.

Please note that the TFS breaks off the
telephone connection automatically after
30 sec. if no entries are made in this time.
