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 factory-set to 15 °C and to 30 °C for cooling.

Protection mode

Use control parameters P65 and P66 to adjust the Protection mode setpoints.

 

The heating setpoint is factory-set to 8 °C (frost protection) and to OFF for cooling.

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!
