Low flow rate error
• in case of low flow rate in 30 sec during water pump signals is ON(Starting)

Normal flow rate error
• in case of normal flow rate in 10min during water pump signal is OFF

f
Water pump ON ( Low flow rate ) : NOT enough water flow
Water flow < 12LPM(Outdoor unit capacity > 9kW)
Water flow < 7LPM(Outdoor unit capacity ≤ 9kW)
E912
f
Water pump OFF ( Normal flow rate )
Water flow > 12LPM(Outdoor unit capacity > 9kW)
Water flow > 7LPM(Outdoor unit capacity ≤ 9kW)
