7.1.1 PARAMETERS INVOLVED
• ErA: energy saving algorithm
• i1F or i2F: set as door input to monitor the appliance usage
• StE: interval to switch from normal to energy saving mode
• EtS: interval to switch from energy saving to normal mode
• HES: SETPOINT differential when energy saving mode active
• HYE: regulation differential when energy saving mode is active
• dS: interval for door opening detection
• LdE: light output controlled by energy saving (OFF when energy saving mode is active)
FROM
TO
MODE
Normal
mode
Energy
Saving
Activate the ECO function from Virtual Keyboard screen.
Door continuously closed for time StE.
Energy
Saving
Normal
mode
Activate the ECO function from Virtual Keyboard screen.
Controller in ES mode for time EtS.
If the controller is in ES mode, it returns in Standard mode when the door
stays open more than time dS.
NOTE: the cycling mode (ES - Normal mode - ES - etc.) works if i1F=dor, EtS and StE are different from
zero. If EtS=0 or StE=0, the controller will not change the operating mode, and it will be possible to change
from the normal mode to the energy saving mode by using the ES button or by setting i1F=ES.
8. PULL DOWN FUNCTION
The Pull Down is automatically activated:
• After any defrost cycle
• After power-on if T>SET+CCS
• When the regulation probe temperature T is:
o T>SET+HY+oHt value in normal mode
o T>SET+HES+HYE+oHE value in energy saving mode
In these cases, a different set-point value (SET+CCS) will be used. As soon as the room temperature
reaches the SET+CCS value, the compressor will stop and the normal regulation will restart.
NOTE:
• Pull Down function is disabled when CCS=0 or CCt=0.
• The CCt parameter sets the maximum activation time for any pull down. When CCt expires, the Pull
Down will be immediately stopped and the standard SET-POINT will be restored
9. DEFROST OPERATIONS
Any defrost operation can be controlled in the following way:
• EdF=rtC: by using an internal real-time clock (only for models equipped with RTC)
• EdF=in: timed defrost, in this case a new defrost will start as soon as the idF timer elapses
9.1 TIMED OR TEMPERATURE CONTROLLED MODE
Two defrost modes are available: timed or controlled by a temperature probe. A couple of parameters are
required to control intervals between defrost cycles (idF) and maximum duration (MdF). During a defrost
cycle it is possible to select some different visualizations by using the par. dFd. Available defrost types are:
• tdF=EL: with an electric heater
• tdF=in: by using hot gas cycle
10. EVAPORATOR FAN
To enable the evaporator fan management it is required to set an evaporator probe (par. FAP). Here are the
involved parameters:
• FAP: to select the control probe
• FSt: to select the deactivation setpoint
