Injection control

Table 30: Injection control → Injection control A
Function Description
Control state A Readout of the actual control state of the controller
Thermostat air Thermostat temperature
temp. A
S4 Air OFF evap. A Actual sensor value
EEV opening A Actual status of output function
Pe Evap. pressure Actual sensor signal
Te Evap. temp. Temperature converted from pressure
S2 Gas outlet A Actual sensor value
Superheat A Readout of actual superheat at the outlet of the evap-
orator
Superheat reference Readout of the actual superheat reference
A
Min. superheat limit Min. value for the superheat reference
Max. superheat limit Max. value for the superheat reference
MOP temperature MOP temperature. The valve opening degree is re-
duced until the evaporating temperature reaches the
set MOP limit. If no MOP function is required, select
the highest value that corresponds to OFF
AKV Period time Period time for the pulse width modulation
Min superheat liq- Min. value for the superheat reference during adap-
uid ctrl tive liquid control
Max superheat liq- Max. value for the superheat reference during adap-
uid ctrl. tive liquid control
