Day/night control
This function transmits a signal to selected controllers. The signal
can be used for raising the temperature reference and for raising
the suction pressure reference.
When the individual controllers receive the signal, the reference
will be changed by the value set in the individual controllers.
Time schedule
The override function enables you to dene a number of time
schedules.
Example of use:
Input signal for day/night control.
Defrost control
The override function enables you to dene and start a number of
defrost cycles.
When the defrost has been started, it is up to the individual
controllers to determine how it is to be terminated again. In some
it may stop based on time, in others based on temperature.
Stopping liquid injection on service
interruption (Inject on)
All controls controlling an expansion valve have an "Inject on"
function. By activating this function the control will close the valve
so that no uid ows through the evaporator.
In this way it is ensured that the valve closes when the compressor
has stopped due to a service interruption.
The function can be created directly via wire connections bet-
ween a compressor control and the current controllers or it can be
created via data communication from a compressor control and
via a system unit to the current controllers.
