Function of the keys in programming
Basic initial configuration
G
Set point (SP)
It defines the temperature that should be inside the cold storage room:
Ÿ
Minimum: –40.0 *
Ÿ
Maximum: 320 *
*(Depends on the bottom/top locking of the set point).
Calibration of Probe 1
It allows correcting the temperature detected by probe 1, this is particularly useful when the probe cannot be
located in the ideal place.
v
Pressure controller config.
It chooses the correct option depending on the type of pressure switch and their connection (See page 19):
Ÿ
Combined HP-LP: A HP-LP pressure switch is used.
Ÿ
LP indep. AC input: The low pressure switch is separate and is connected to the AC input (Terminal 22).
Ÿ
LP indep digital input: The low pressure switch is separate and is connected to the digital input 2.
q
Connected sensors
Choose the correct option according to the no. of probes connected:
Ÿ
Sensor 1: If it has just one control probe. Defrost will end by time.
Ÿ
Sensor 1 and 2: If it has two probes, a control probe and another one for defrost (evaporator).
Ÿ
Sensor 1 and 3: If it has two probes, one for control and another for data logging or product temperature
(according to
Probe setting
), defrost will finish by time.
Ÿ
Sensor 1, 2 and 3: If it has three probes, one for control, and another for defrost and another for data
logging or product temperature (according to
Probe setting
).
