6.1 Preliminary notes
Operating Statuses:
-
“on” state (the device is powered and is on: the
regulators can be switched on)
“stand-by” status (the device is powered but is
-
switched off via software: the regulators are
switched off; the possibility to turn the room light
or the auxiliary output on/off manually depends on
parameter u2)
-
the “off” status (the device is not powered).
Hereafter, with the word “start-up” means the passage from
“stand-by” status to “on” status; the word “shutdown” means
the passage from “on” status to “stand-by” status.
When the power is switched back on, the device displays the
status that it was in at the time it was disconnected.

6.5 "Rapid cooling" function
Displaying the magnitude detected by an analogue input
enabling/disabling
To enable/disable the "rapid cooling" function, proceed as
follows:
1.
Check that the device is turned on, that the
keypad is not locked, that no procedures are in
progress and that there are no defrosting, dripping
or evaporator fan stop operations in progress.
Keep the "UP" key pressed for 4 s: the
2.
"temperature" LED light shall start flashing.

"Rapid cooling" function enabling/disabling
EVCO S.p.A. EVBOX1 | Installation guide ver. 1.2 | Code 144BOX1E124
During the "rapid cooling" function the work set point is
decreased by the temperature set with the r5 parameter; the
function runs for the span of time set with the r6 parameter.
During the "rapid cooling" function the defrosting function is
never activated; if the defrosting interval expires while the
rapid cooling function is in progress, the defrosting shall be
activated at the end of the cooling.
6.6 Defrosting manual activation
To activate the defrosting in manual mode, proceed as follows:
1.
Check that the device is turned on, that the
keypad is not locked, that no procedures are in
progress and that the "rapid cooling" function is
not in progress.
Keep the "DEFROSTING" key pressed for 4 s.
2.
If the evaporator temperature sensor functions as a defrosting
sensor (that is to say,if the P3 parameter is set to 1) and when
the defrosting starts the evaporator temperature exceeds the
value set with the d2 parameter, the defrosting shall not be
activated.
6.7 Turning on/off of room lights
manually (only if the parameter

light" LED shall turn on/off.
Through the digital ports it is also possible to turn the room
light on/off from remote; see parameter u2.
If parameter u1 and/or parameter u11 are set to 2 (that is to
say, if the application managed by the K5 and/or K6 outputs is
the auxiliary output), pressing the "AUXILIARY" key for 2 s
shall make the "auxiliary 1" and/or "auxiliary 2" and the
auxiliary output LEDs turn on/off.
