Button lock

Press operating mode button

for 7 seconds to lock or unlock the buttons if

manual button lock is configured (parameter P14 = 2).

The thermostat automatically locks the buttons 30 seconds after the last

adjustment if "Auto lock" is configured (P14 = 1).

The key symbol

indicates locked buttons.

Commissioning (by qualifie

d HVAC installer)

To adapt the thermostat to your system and optimize the control performance, a number

of control parameters can be adjusted. This can also be made during operation without

opening the thermostat.

Control sequence

Recalibrating the sensor

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!

Control parameters

Proceed as follows to change the most important control parameters:

(Your HVAC installer can set additional parameters)

+ / -

1. Set the thermostat to Protection

2. Press - and + simultaneously for a minimum of 3 seconds.

Release them and, within 2 seconds, press + again for 3 seconds. "P01" is displayed.

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

4. Press + and – simultaneously, the current value of the selected parameter starts to flash, allowing you to change

the value by repeatedly pressing + or –.

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

6. Repeat steps 3 to 5 to display and change additional parameters.

7. Press + or – until "End" is displayed, and then press + and – simultaneously to save the change and exit parameter

entry mode. 10 seconds after the last display or setting, all changes are saved and the thermostat will leave parame

entry mode.

 Please record all changes you make! (All temperature settings can be made in increments of 0.5 K)

FIL

This message reminds you to clean the filter on your HVAC equipment.

It will appear after  __________ "fan operating hours" and disappear when

the thermostat is set to Protection (

). This reminder must be configured by

your HVAC installer.

AL1

AL2

This alarm message tells you an external alarm has occurred:

AL1 : ______________________

AL2 : ______________________

The alarms are configured by your HVAC installer

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 and single duct application is "Cooling only",

and for 4 pipe application "Heating and Cooling"

If the room temperature displayed by the thermo

stat 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.
