5.9. Fan Heater Operation
For operation modes 0 and 3, that provide for the combination
with one or more fan heaters code ABXXXIT-00H0, in addition
to the management of boiler and heat pump operation, a 0-10V
signal is sent to the fan heater for the automatic management
of the rotation speed of fans.
The rotation speed is controlled according to the following
parameters that can be set on boiler CPU_PLUS PCB.
Par. Description Default value
H12 Minimum speed voltage 4 V
H13 Maximum speed voltage 10.0 V
H18 Conditioning voltage 4 V
H19 Minimum speed temperature 35°C
H20 Maximum speed temperature 60°C
During operation in heating mode, the value of 0-10V signal
sent to the fan heater depends of the reading of AQUAPUMP
water delivery temperature probe (NTC1 probe - boiler delivery
probe) and varies linearly between the minimum voltage value
(par.H12) at the temperature corresponding to the minimum
speed (par.H19) and the maximum voltage value (par.H13) at
the temperature corresponding to the maximum speed (par.
H20) as described in the graph below.
During operation in conditioning mode, the voltage value sent
to the fan heater is a value corresponding to par. H18.
During operation in domestic hot water production mode, the
voltage value sent to the fan heater is 0V, therefore ventilation
will be interrupted as long as DHW production is required.
To change fan heater speed adjustment parameters, refer to
paragraph (6.10).
5.10. Hydraulic circuit filling
Filling or water replenishment operations are the same for all
models.
FILLING:
• Make sure that connections between indoor unit/system
and AQUAPUMP HYBRID have been carried out correctly,
respecting delivery and return direction;
• Make sure that automatic vent valves, placed on the
circulator or on the boiler and on the fan heater battery/
ies are open.
•
Using an effective filling system, connect the system to a
pump for system test with reservoir filled with water and
glycol (if required). Load the mix until a pressure of approx.
2 bar is reached.
• Vent the pipe;
• When venting operation is over check, through the display,
that the pressure inside the circuit is greater than 1bar; lower
values will cause an F80 because of the activation of water
minimum pressure switch [calibration 0.6bar].
Water-glycol mix restoration
In the event of water leakage and/or need to refill the hydraulic
circuit, after having detected and solved any leakages, it is
necessary to restore water-glycol mix by following the instructions
described above.
GLYCOL
For its machines, APEN GROUP tested and recommends to use
ALPHI 11
glycol by Fernox; the following KITS contain packs
with different capacity:
code
capacity
C07200-05 5 litres
C07200-25 25 litres
The use of glycol having different chemical composition
shall invalidate the exchanger warranty.
N.B. The indicated glycol percentages refer to the parts contained
in the mix (water/glycol) and not in addition to water, e.g.: a
10-litre mix with 30% glycol is composed of 7 litres of water
(70%) and 3 litres of glycol (30%).
NOTE: Glycol percentages and limit temperatures indicated
on page 23 have information purposes; we remind that the
boiler is certified for use with external temperatures up to,
and not exceeding, -15°C.
