Regulation - Eliwell V800 Series Manual

REGULATION

PID / H60
V800 calculates the real overheating by using the two analogue inputs overhaeting and saturaion probes.
Through a PID controller it modulates the valve opening to reach OLt setpoint The algorithm is dynamic: the effective
overhaeting value could not reach setpoint or temporarirly decreases under setpoint value. Evaporator liquid leakage may
occours: in this case increase Setpoint OLt to prevent it.
PID configuration parameters will be automatically uploaded by the device by selecting plant type defined by H60.
MOP (Maximum Operating Pressure)
MOP regulation defines a threshold set by pressure setpoint HOt. If the threshold has been exceeded for tAP period, an MOP
alarm will show up.
MOP regulation can be disabled:
• via HOE parameter
• at power -on / after defrost for an HdP period
