It is possible to control the timer-thermostat remotely with a phone
dialler connected to the terminals.
By closing the contact, the thermostat is forced onto manual opera-
tion and the keys are locked.
On opening the contact the timer-thermostat is forced onto:
• Antifreeze mode if heating is on.
• OFF if air-conditioning is on. In this phase the keys of the timer-
thermostat are not locked and it is possible to operate the de-
vice.
