Duration * : P68 = 0...360 min, factory setting = 0 min.
Button lock
Press operating mode button for 3 seconds to lock or unlock the buttons if
manual button lock is configured (parameter P14 = 2).
The thermostat automatically locks the buttons 20 seconds after the last

Note: Economy mode
The Economy setpoints are factory-set to 15 °C for heating and 30 °C for
cooling. Use parameters P11 and P12 to adjust the values.
Important: You can set these setpoints to OFF; the thermostat then is
inactive, i.e. no protective heating or cooling function.
Risk of frost!
Commissioning
You can adjust a number of different control parameters to adapt the thermostat to your
system and optimize control performance. You can do this during operation either via the
buttons on the thermostat or using a commissioning tool.

*** Parameter P13 is only displayed for application "2-pipe with el heater".
All temperature settings in increments of 0.5 °C.
The control parameters displayed depend on the DIP switch settings made  Please record all changes you make!
The thermostat can be used in systems either for heating only or cooling
only, manually selection of heating or cooling, or automatic heating / cooling
changeover. Depending on the selected application, the relevant modes are
available and can be adjusted by commissioning parameter P01 if needed.
The factory setting for 2-pipe application is "Cooling only", and for 4 pipe
application "Heating and Cooling"
If the room temperature displayed by the thermostat does not agree with the
temperature effectively measured (after min 1 hour of operation), the tem-
perature sensor can be recalibrated. With parameter P05 the temperature can
be adjusted by + or – 0.5 °C up to a maximum of + / - 3 °C.
