12 - FACTORY OPTIONS AND ACCESSORIES
●
Coil
fi
lling:
- The coil
fi
lling must be made with the bleeder valve open
until water runs through it, which is when it is time to close it.
- Cut o
ff
the water supply and let the bubbles generated go
up to the highest coil point, which is the same as the bleeder
valve, and eliminate by opening the purger.
- Pour more water into the circuit and repeat the previous
steps.
- Activate the water pump (to be foreseen by the installer,
except with the GREAT COLD option) and repeat the
●
The pump of the water circuit has to be activated whenever
the 3-way valve is switched on. It is the installer’s responsibility
to connect the pump to the electronic control, except with the
factory-installed GREAT COLD option. Please refer to the
wiring diagram provided with the unit.
Operation of the pump with the GREAT COLD option
(upon
request
:
- Antifreeze protection: if the water temperature in the coil
drops below 4ºC, the control activates the pump and the
3-way valve opens to 100%. The pump stops when 7°C are
reached.
- Safety of minimum outdoor temperature: if the outdoor
temperature drops below 4ºC, the control activates the
pump and the 3-way valve opens to maintain, in the water
coil, a water outlet temperature of 10ºC in ON operating
mode and 15ºC in OFF operating mode.
12.8 Hot water coil
●
Hot water coil with a three-way valve managed by the
electronic control of the unit. The water coil could be activated
in the following cases:
- As a backup in HEATING mode, following the input of all the
available compressors (by default) or as
fi
rst control stage.
- As a backup in HEATING mode in accordance with the
supply temperature.
- During the defrosting operation if selected as backup.
- With the unit running or shut down if an anti-freeze alarm
is triggered.
- With the unit stopped when the outdoor temperature drops
below 4ºC. In this case the circulation pump of the water
circuit is connected.
- As a backup in COOLING mode in accordance with the
return and the outlet temperatures.
Note: the hot water coil is not compatible with the stop-drop
in the indoor coil or the heat recovery coil.
●
This option always incorporates an anti-freeze thermostat
as safety system. This thermostat is accessed via the same
panel used for the electrical heaters, if necessary to reset the
safety. Consult the images on the previous paragraph.
- Great Cold option
(upon request) : with additional anti-
freeze technology based on the water temperature. This
protection is made up of a circulation pump as well as two
probes inserted in the input and the output of the coil.
Important: this option is mandatory for an outdoor
temperature lower than -20ºC WB. Consult for percentages
of glycol water above 20%.
These connections can also be made via the base of the
unit using
fl
exible piping (for installation with pre-assembly
roofcurb).
The position of the sheet metal precuts on the pre-assembly
roofcurb are shown in the following diagram.

The inlet/outlet connections of the hot water coil are located
inside the unit and the connection is made via the side panel.

●
In case of long unit stops, and forcibly if they happen in the
winter season, the coil must be emptied.
●
To prevent the water from freezing, with this option the unit
always has an anti-freezing thermostat. Add glycol to the water
if necessary.

The direction of the water
