If a setpoint is set to OFF (P65, P66), the thermostat does not maintain the setpoint
in the corresponding mode (heating or cooling).
This means no protective heating or cooling function and thus risk of frost in the
heating mode or risk of overtemperature in cooling mode!
4.4 Setpoints and sequences
On single-duct changeover applications, the Comfort setpoints for heating and
cooling sequence are the same (w).
On applications with electric heater, radiator or heating/cooling coil, the Comfort
setpoint is at the heating sequence.
The start of the cooling sequence is linked to "Dead zone" above the Comfort
setpoint. The dead zone can be set via parameter P33.
The setpoints for Economy and Protection mode are below the Comfort setpoints
(heating) and above the Comfort setpoints (cooling).
They can be set via parameters P11, P12 (Economy mode) and P65, P66
(Protection mode).
The control signal for air flow can be limited via parameters P63 and P64.
See section 4.8.1.
To simplify the diagram below, only minimum limitation is shown.
