Door open
The door microswitch must be connected to the primary unit
controller in the network.
As for the lights, also the door status is shared to all controllers.
Every controller knows if the door(s) is/are open or not, and each
controller can perform actions.
Network temperature regulation
INFORMATION
To change parameters related to this functionality,
"Service" level access is required.
The temperature regulation can be performed in two ways
depending on the parameter "nrt" with the following values:
▪ 0: The relative controller regulates through the probe connected to
itself.
▪ 1: The relative controller regulates through the probe connected to
the primary unit controller.
The network logic allows avoiding simultaneous starts of
compressors. Using the "SSd" parameter it is possible to set a delay
between starts of different LMCEY units.
If it is necessary to start several units at the same time, the first unit
to signal to start will be the first one to start. After "SSd" the next unit
will also start and so on (See the example below).

Note: LMCEY2A/W units have two compressors, but work in a
similar way. The two compressors of the same unit work
synchronously.
Network defrost
INFORMATION
To change parameters related to this functionality,
"Service" level access is required.
It is possible to enable/disable this functionality for each controller
separately.
Defrost can be synchronised between the primary unit controller and
secondary unit controllers using parameters dS_1, dS_2, dS_3, and
dS_4 with the following values:
▪ 0: No synchronisation performed.
▪ 1: Only starting.
Only starting: secondary unit controllers will start to defrost at the
same time as the primary unit controller, and all controllers can
finish in different moments.
▪ 2: Start & Stop.
Start & Stop: secondary unit controllers will start to defrost at the
same time as the primary unit controller. If one controller ends
defrosting before the others, the corresponding defrost relay is de-
energised and the dripping phase will only start when all other
controllers have finished the defrosting phase.

Local defrosting on a LMCEY unit is still possible in two ways:
▪ Manually (from app, supervisory system or user interface).
▪ If not manually started, each unit will perform a defrost every 4
hours to allow the correct operation of the unit.
