Symptom 8: DHW mode can't change to Heat mode immediately
POSSIBLE CAUSES
Heat exchanger for space
heating not big enough
Space heating load is small
Disinfect function is
enabled but without TBH
Symptom 9: DHW mode heat pump stop work but setpoint not reached, space heating require heat but unit stay in DHW mode
POSSIBLE CAUSES
Surface of coil in the tank
not large enough
TBH or AHS not available

The power consumption parameter is preparatory. some parameter is not be activated in the system, the parameter will
show "--"
The heat pump capacity is for reference only, not used to judge the ability of the unit. The accuracy of sensor is ±1℃.
The flow rates parameters are calculated according to the pump running parameters,the deviation is different at different flow
rates,the maximum of deviation is 25%.
• Set "t_DHWHP_MAX" to minimum value, the suggested value is
60min.
• If circulating pump out of unit is not controlled by unit, try to
connect it to the unit.
• Add 3-way valve at the inlet of fan coil to ensure enough water
flow.
Normal , no need for heating
• Disable disinfect function
• add TBH or AHS for DHW mode
The same solution for Symptom 7
Heat pump will stay in DHW mode untill "t_DHWHP_MAX" reached or
setpoint is reached. Add TBH or AHS for DHW mode,TBH and AHS should
be controlled by the unit.
