CAUTION
If a
setpoint (Economy or Protection) is set to OFF, the thermostat does not
control the room temperature in the corresponding mode (heating or cooling). In
other words, there is no protective heating or cooling function and thus risk of
frost in heating mode or risk of overtemperature in cooling mode!
The Economy setpoints (P019, P020) are accessible at the Service level; the
Protection setpoints (P100, P101) are accessible at the Expert level.
