4.3Setpoints
Comfort mode | The setpoint in Comfort mode can be adjusted via the rotary knob. |
Setpoint limitation | For Energy Saving purposes, the setpoint adjusting range can be limited to |
| minimum (P09) and maximum (P10). |
P09 < P10 | • If the minimum limit P09 is set lower than the maximum limit P10, both heating |
| and cooling are adjustable between these two limits. |
P09 ≥ P10 | • For heating or cooling applications (e.g. single duct; single duct & H/C coil) |
–The setting range in cooling mode is from P09…40° instead of 5…40°
–The setting range in heating mode is from 5…P10° instead of 5…40°
•For cooling and heating with electrical heater or radiator applications
–P09 is the setpoint for cooling and P10 the setpoint for heating;
–the setpoint can no longer be adjusted via rotary knob

Temporary setpoint | If the “Temporary setpoint function” is enabled via parameter P69, the setpoint |
| adjusted via rotary knob is set back to the Comfort basic setpoint when the |
| operating mode changes. |
| The factory setting for the Comfort basic setpoint is 21 °C and can be changed via |
| parameter P08. |
Energy Saving mode | Use control parameters P11 and P12 to adjust the Energy Saving mode setpoints. |
| The heating setpoint is |
Protection mode | Use control parameters P65 and P66 to adjust the Protection mode setpoints. |
| The heating setpoint is |
Caution | 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 overheat in cooling mode! |
