CHRONOS KEY Programmable Thermostat User Manual
Remotely switching off (only for battery powered models)
The battery powered Chronos Key have a settable input for the connection of an
external probe or a clean contact. The free contact can be conncted to a telephone
activator to switch on/off the programmable thermostat remotely by their own
telephone.
The contact can have one of these two positions:
- open à normal operation (according to the settings)
- closed à programmable thermostat in off mode
Remote off status is displayed with the fl ash of the symbol
on fi eld (9) to
differentiate it from the keypad off status (
fi xed on fi eld (9)).
Attention: remote off status (closed contact) is more important than any
other programming, so the instrument will be in off status until the contact
does not turn back to the open position.
