For basic details on how to use the hand-held terminal, 
see the Operation and Maintenance Instructions for the 
GOLD Air Handling Unit.

The functions for the reversible heat pump are activated 
manually under Functions/HC. This is only possible for 
GOLD RX (rotary heat exchanger).

HC is activated by setting Position HC in On. Other possi-
ble settings are shown when HC is activated.

If any of the accessories electric air heater HC or air 
recirculation section HC are fi tted, these are activated 
by selecting the required accessory from the menu HC 
defrosting accessory.

Set the required heating and cooling function, standard or 
comfort. 

Set the required values for outdoor temperature limits for 
heating and cooling.

Set the required values for airfl ow limits for supply air and 
extract air.

Calibration is carried out at the factory. If recalibration is 
required, this can be carried out by pressing the calibra-
tion button. Remaining time is shown when calibration is 
in progress. Calibration date and lowest/highest air fl ow/
pressure drop are shown when calibration is performed.
