Hi,
Check if you have severe fluctuations in water flow.
If it is OK then you should have problem with the sensors or you have to open the EXV and clean it. Sensors are located after the EXV and after the evaporator.
The unit model number should be RTWB212

check the calibration of temperature sensor evaporator and saturated suction temperature, water flow is correct? refrigerant charge is correct? gives more information to help
