Description of the device
1 .5 .1 Indoor unit
PDC FLOOR combines three functions - winter heating, summer
cooling and heating of hot water - in one device. On demand,
the machine may be equipped with 6 kW auxiliary resistors and
with the solar circuit components on-board (which can be as-
sembled also after installation).
The following components are integrated in the indoor module:
brazed heat exchanger plates
P1 primary circulation DC pump (class A)
inertia tank, 200 litre capacity, with instantaneous serpentine
heat exchanger (4 m2) made of AISI 316L stainless steel for
making hot water
system hydraulic separator
24 litre system expansion vessel (48 for solar energy models)
safety valves
ACS diverting valve
on-off taps
screen filter for system water
automatic vents for perfect air bubble removal.
A P2 secondary circulation pump (electronic, class A) is available
as accessory (fitted in the device) downstream of the hydraulic
separator. This configuration ensures complete separation be-
tween the primary and the secondary circuit with consequent
safety and functional stability of the heat pump which is no
longer subject to flow rate fluctuations caused by circulation on
system side.
Hydraulic and cooling connections (for connecting to the exter-
nal unit) are arranged on the top of the module so avoid increas-
ing side dimensions.
Access is from the front only to reduce clearance needed to the
front only.
The electric panel is provided with a master switch and is en-
closed in a IP44 sealed casing. The electronic control can be con-
nected (by installing a switch) by means of WEB SERVER to any
PC or smartphone logged onto the Internet and has a user in-
terface with large touch screen for remote control, if required. A
user interface (of the type fitted on eHPoca devices as standard)
for emergency operations.
The following components are integrated in PDC FLOOR versions
set up to connect to solar panels: circulation pump for PSO solar
panel fluid, electronic control unit, safety valves, solar fluid pres-
sure gauge, 24 litre expansion vessel on solar circuit, thermostat
mixing valve to avoid excessively hot water temperatures.
The system is also provided with attachments for an auxiliary
boiler to configure a hybrid type solution for high average tem-
perature radiators, like heated towel rails. This solution allows to
maintain very low delivery temperatures in the primary system
and supply higher temperature water to some radiators without
compromising the Seasonal Coefficient of Performance (SCOP)
of the heat pump.
A P3 high temperature circulation pump is available as acces-
sory (fitted in the device) and may be controlled by an external
thermostat.
