PPUH „GECO” EDITION I PRINTOUT DATE 2014-03-27
Damage of the chamber temperature sensor will make the display show the A1 symbol. The
controller will activate the compressor in the time cycle (clock-based control) in accordance with
times specified in ‘c8’ i ‘c9’ parameters. The defrosting process will function as usual.
If the evaporator sensor is damaged, the display will show the A2 symbol. The manual and
automatic defrosting is blocked then!!! The only possibility of defrosting the unit is to press the
pushbutton in order to turn off the unit, and then wait for the ice to thaw.
If two sensors have been damaged, only the A1 symbol will be displayed.
Having repaired the chamber sensor, the A2 symbol will start to be displayed.
10. If the buzzer has been installed in the controller – see p. II, the buzzer will signal any pressing of any button.
If the controller is turned off (two horizontal dashes on the display are seen then), the buzzer will signal
only if the following pushbuttons are pressed, namely: and .
11. The lighting system activation and deactivation will take place after pressing the pushbutton. This will
be signalled by the green LED. If the door opening is reason for lighting system activation, the green LED
will not light up.
The button will operate independently of the thermostat current switch over - .
12. If the ‘d6’ is set to a value lower than 40 ºC, the controller shuts down the fan when the evaporator
temperature is higher than the ‘d6’ parameter value. This function is not available in the defrosting mode.
B - Defrosting
1. If the necessity for the additional defrosting occurs, due to difficult operating conditions, press the
pushbutton. This will make the green LED light constantly on the pushbutton, while the „dF” symbol will
appear on the display, rather than temperature measurement symbol, and this is where the unit will enter
the defrosting cycle.
2. If the defrosting occurs, and the temperature on the evaporator is higher than set in the ‘d2’ parameter, the
unit, after some 10 seconds, will enter the defrosting exiting mode, to resume the operation when the said
mode terminates.
3. If the defrosting occurs, and the temperature on the evaporator is lower than set in the ‘d2’ parameter, the
G-202-P00 will activate the defrosting process, and after reaching the temperature as specified in the ‘d2’
parameter, the unit will enter the defrosting exiting mode (this status is signalled by the green LED, which
blinks on the pushbutton). The heaters version will then enter the defrosting exiting mode, comprising
two consecutive Phases:
Thawing Phase – where the compressor and fans are turned off for the period as specified by the‘c3’
parameter;
Evaporator Freezing Phase – where only the compressor is operated, in order to lower the temperature
of the evaporator to the temperature as specified by the ‘d5’ parameter, prior to reactivating the fans.
The maximal freezing time can not be exceeded, regardless of whether the evaporator has achieved the
temperature of ‘d5’, specified by the ‘c4’ parameter.
