TCC Function
The TCC
function
enables the possibility of reaching higher water temperatures when an
alternative electric energy source is available (solar PV, wind, hydro) increasing the efficiency of the
thermodynamic solar system and maximising the alternative electric energy source.
Firstly, turn the power off to the system.
Undo the three screws and remove the top cover from the
system, then undo the four screws and remove the cover
plate on the electronic control unit.
Connect a pair of wires from an inverter relay to terminals
1 and 2 on the inputs at the top left of the control board.
These are the two connections on the left of the green
input block in the picture
.
Be careful that this is a dry contact (without power). Applying power to this contact may cause
irreversible damage to the control board.
When the contact K1 closes, it activates the TCC function and the compressor and electric heater
will operate to the TCC set points. This function will be indicated on the display.
The compressor will operate to parameters P01TCC and H01TCC and the electric heater will
operate to P02TCC and H02TCC.
Note: When the contact K1 is open, the equipment will assume the previous working mode (Eco,
Auto or Boost) and its previous parameters.
The K1 contact may also be used to take advantage of tariff with variable price. Other options are a
temperature switch, or a wifi switch. To do this, connect a timer or switch to the 1 and 2 contacts.
Note that this relay or switch must be a dry contact switch. It must have no power supply on it
.
If you set your equipment to
Holiday
mode
DO NOT turn it off
with the key ON/OFF
,
or the function will become inactive
.
If you do switch it OFF, or you come home early when you return from
your holidays you must remember to switch on your equipment and
cancel the days of holidays introduced (set the value to 0).
If you do not set the value to 0, your equipment will not restart
until the days of holidays selected have expired.
