Please note:
If only one zone is used, the ZONE/HEAT key can be used for switching on
and off the fans. This switching on and off of the four fans is done in the
same way as switching on and off zones.
The PROBA offers the option to switch off the heating. During temperature
control there will only be cooling. If the temperature is lower than the
setpoint, the heating will not switch on.
Make sure that the key switch is in the PE position.
Press the SET key and next the ZONE/HEAT key. The LED above the key
flashes to indicate this function is active.
The lower display shows the text 'HEAt'.
The upper display shows if the heating is to be switched ON or switch OFF.
Using the UP and DOWN keys the status of the heating can be changed.
Press the SET key to accept the setting.
To prevent unauthorized use, rotate the key switch to ON and remove the
key.
Please note:
If heating is switched off and heating is required by the control, the HEAT
LED's on the front of the PROBA start flashing, to indicate that the HEAT-
OFF function is active.
