Use control parameters P65 and P66 to adjust the Protection mode setpoints.
The heating setpoint is factory-set to
8 °C (46 °F)
(frost protection) and to
OFF
for
cooling.
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!
The Economy setpoints are accessible at the service level (P11, P12); the Protection
setpoints at the expert level (P65, P66).
4.4 Setpoints and sequences
4.4.1 2-pipe and 2-stage applications
On changeover applications, the Comfort setpoints for heating and cooling sequence
are the same (w).
On 2-pipe applications with electric heater, the Comfort setpoint is either at the first
heating sequence (in heating mode) or at the cooling sequence (in cooling mode).
On 2-pipe applications with radiator, the Comfort setpoint is either at the radiator
sequence (in heating mode) or at the cooling sequence (in cooling mode).
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).
