(10) if parameter P3 is set at 0 or 2, the instrument will function as if parameter d8 is set at 0
(11) if, on activation of defrosting, the switch-on duration of the compressor is less than the time established with parameter d15, the compressor will remain on for the fraction of time required to complete it
(12) if parameter P3 is set at 0, the instrument will function as if parameter A0 is set at 0 but will not memorise the alarm
(13) during defrosting, dripping and evaporator fan standstill, the temperature alarms are not present as long as these have occurred after activation of defrosting
(14) during the activation of the door micro switch input, the maximum temperature alarm is absent on the condition that these occur after activation of the input
(15) the alarm is always signalled when the power supply is restored
(16) if parameter P3 is set at 0, the instrument will function as if parameter F0 is set at 2
(17) the parameter is also modified by operating with the procedure given in paragraph 4.8.1
(18) if parameter P4 is set at 0, the condenser fan will function in parallel to the compressor
(19) the compressor is switched-off after 10 s from activation of the input. If the input is activated during defrosting or standstill of the evaporator fan, the activation will not have any effect on the compressor
(20) the instrument memorises the alarm on expiry of the time established with parameter i2. If parameter i2 is set at -1, the instrument does not memorise the alarm
(21) make sure that the time established with parameter i7 is lower than that established with parameter i9
(22) to prevent damage to the utility connected, modify the parameter when the instrument is off
(23) if parameter u2 is set at 0, instrument switch-off will cause the cabinet light or auxiliary output to switch off (on successive switch-on of the instrument, the utility will remain off); if the parameter u2 is set at 1, instrument
switch-off will not cause the cabinet light or auxiliary output to switch off (on successive switch-on of the instrument, the utility will remain on).

ELECTRIC CONNECTION
13.1
Preliminary considerations
With reference to the wiring diagram:
• the utility managed by the fourth output will depend on parameter u1
• the serial is the port for communication with the Parameters Manager set-up software system or to the monitoring and supervision system of RICS plants (through a serial interface, via TTL, with MODBUS communication
protocol) or with the EVKEY programming key. The port must not be used simultaneously for three purposes.

Electric connection
13.3
Recommendations for the electric connection
• do not operate on the terminal boards using electric or pneumatic screwdrivers
• if the instrument has been taken from a old place to a hot one, the humidity could condense inside. Wait about one hour before applying power
• make sure that the power supply voltage, frequency and operational electric power correspond to those of the local power supply
• disconnect the power supply before performing any type of maintenance
• do not use the instrument as a safety device
• for repairs and information regarding the instrument, contact the Evco sales network.
