Cause of fault and corrective action
1. The signal wires of the slave units and of the master unit are not
connected effectively. After having checked that all the signal wires
are properly connected, and having made sure that there is no strong
electricity or strong magnetic interferences, switch the unit back on.
2. There are two or more outdoor units connected to the control panel.
After having removed the extra control panel and having kept only
the control panel of the master unit, switch the unit back on.
3. The ignition interval between the master unit and the slave unit
is longer than 2 minutes. After having made sure that the interval
between ignition of all the master units and slave units is less than 2
minutes, switch the unit back on.
4. The addresses of the master units and of the slave units are repeated;
pressing the key SW2 on the main board of the slave units once, the
address code of the slave unit will be displayed (Normally address
code, one of 1,2,3 ... 15 will be displayed on the main board), check
whether it is a duplicate of the address. If there is a duplicated ad-
dress code, after having switched the system off, set S4-1 at ON on
the main board of the master unit or on the main board of the slave
unit displaying the error "Hd" (refer to Chap. 10.1.1 Setting of the
function). Switch all the units back on for 5 minutes without error
"Hd", switch back off and set S4-1 at OFF. The system is reset.
The control board RT/Ta PCB is set to be valid on the control panel
but the thermostat transfer board is not connected or communica-
tion between the thermostat transfer board and the main board is
not actually connected. If the transfer board of the thermostat is not
necessary, set RT/Ta PCB at not valid. If the transfer board of the
thermostat is necessary, connect it to the main board and make sure
that the communication wire is properly connected and that there
are no strong electricity or strong magnetic interferences.
1. The EEprom parameter is in error, rewrite the EEprom data.
2. The EEprom component is damaged, replace the EEprom com-
ponent.
3. The module board of the inverter is damaged, replace it with a
new PCB.
See H6.
See P0.
1. The supply voltage of the unit is low, increase the supply voltage
to the required range.
2. The space between the units is too narrow for the thermal exchange.
Increase the space between the units.
3. The heat exchanger is dirty or something is blocked on the surface.
Clean the heat exchanger or remove the obstruction.
4. The fan does not work. The motor of the fan or the fan is damaged,
replace it with a new fan or a new motor.
5. The water flow rate is low, there is air in the system, or the pump
head is not sufficient. Release the air and select the pump again.
6. The outlet water temperature sensor is loose or damaged; reconnect
it or replace it with a new one.
