Product Storage Temperature; Defrost Mode - UBC AURA Operating Manual

A current temperature inside the useful volume is shown on the controller display. The procedure for changing the
useful volume temperature is described in p. 10. Reading of the temperature sensor is adjusted in programming mode
exclusively by the service provider's personnel.
The useful volume temperature is set in terms of temperature conditions according to the requirements of the
product storage technology and recommendations on the package.
10. TEMPERATURE SETTING FOR THE USEFUL VOLUME OF THE REFRIGERATED
The temperature of the useful volume can be set using the controller in programming mode. If another controller is
coming with the refrigerated display cabinets, its description will be provided in the annex.
The programming sequence for electronic controllers DANFOSS ERC 112С is described below. The front panel
of the controller has a display and four control buttons (see Fig. 5).
To change the temperature of the useful volume of the refrigerated display cabinets, first press and hold button 4
until the desired temperature value appears.
Now you can see figures-values (e.g. +1,0) of the previously set temperature on the controller display, at which the
cooling mode of the refrigerated display cabinets is turned off.
Using button 3 or 4, set a new temperature value (e.g. +1,5). To enter the new value, briefly press button 1 again.
To exit the temperature adjustment mode, press button 2 or do not use the buttons within 15 seconds.
The refrigerated display cabinets has an electronic thermostat with an automatic defrost system.
The defrosting time and time interval between the defrost cycles is changed by the service provider's personnel.
ATTENTION! When setting the time interval between the defrost cycles, the controller system settings are avail-
able that determine the operation of the refrigerated display cabinets. Make sure that their values have not changed.
To change the time interval between two defrost cycles, get access to the menu. When pressing and holding buttons
3 and 4 (simultaneously), enter the code (available only to the service provider). Then use the menu to find the "dEF"
option, and in the submenu "dii" (minimum interval between the defrosts) and submenu "dai" (maximum interval between
the defrosts) set the necessary defrost cycle, e.g. minimum 8, maximum 9, using buttons 3 and 4. Press button 1 to save the
new value.
ATTENTION! Generally, the refrigerated display cabinets is manually defrosted when a large snow cover is
formed on the evaporator due to a wrong choice of the automatic defrost cycle.
To activate manual defrost, press button 2 one time. If there are relevant conditions for defrost, it will turn on, and
the defrost LED will light up.
