Temporary timer to extend the Comfort mode

When Economy mode is active, press operating mode button to tempo-

rarily return to Comfort mode. symbol appears. Press operating mode button again to stop the timer.

You can only extend Comfort mode if parameter P02 = 1. 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 adjustment if "Auto lock" is configured (P14 = 1).

The key symbol indicates locked buttons.

Reminder to clean filters and for external faults

This message reminds you to clean your HVAC equipment filters.

 

It is displayed after ………… “fan operating hours” and disappears when the

 

thermostat is set to Protection (

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.

Control sequence

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"

Recalibrating the sensor

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.

* Needs to be configured by your HVAC installer

Control parameters

Proceed as follows to change the most important control parameters: (Your HVAC installer can set additional parameters)

+/ – 1. Press the – and + buttons simultaneously at least 4 seconds. Release, and within 2 seconds, press + again until "P01" is displayed.

2.Repeatedly press the + or – button to select the required parameter.

+ P01 - + P02 -

+ P08 -

+ P13 - + P14 -

3.Press + and – simultaneously. The current value of the selected parameter begins to flash, allowing you to change the value by repeatedly pressing + or –.

4.The next parameter is displayed when you press + and – again simultaneously.

5.Repeat steps 2 to 4 to display and change additional parameters,.

6.Press + or – until “End” is displayed, and then press + and – simultaneously to save the change and exit parameter entry mode.

15 minutes after the last display or setting, all changes are saved and the thermostat leaves parameter setting mode.
