7 SIGNALS
7.1 Signals
LED MEANING
Compressor LED
if it is lighted, the compressor will be ON
if it flashes, a compressor delay will be running (look at the parameters
C0, C1, C2, C4, n1 and n4)
Defrost LED
if it is lighted, the defrost output will be activated
if it flashes:
• a defrost delay will be running (look at the parameters C0, C1, C2, C4,
n1 and n4)
• the dripping will be running (look at the parameter d7)
• the freezing fluid heating will be running (look at the parameter dP)
(16) do not set more instruments as master
(17) the time between the master implements a control and the slave implements the same control is “n1 x n4”
(18) except the control turning ON and OFF; it will immediately be implemented
(19) if among the remote controls the slave has to implement there is the defrost activation, the parameter d5 will set a time you will have to add to the one you have set with the
parameters n1 and n4 (the slave will implement the control even if the conditions will not allow the master of activating the defrost); if the master is in the STAND-BY mode and
among the remote controls the slave has to implement there is not the turning ON and OFF, the slave will work with the local settings.
11 ELECTRICAL CONNECTION
11.1 Electrical connection
(20) short-circuit terminals 1 and 5 and/or 1 and 7 if you do not use the lock input and/or the compressor thermal protection
(21) the position of the probe for compressor thermal protection could compromise the insulation between low voltage and high voltage parts.
