PLANT HEATER IN DEFROST
During the
defrost cycle
(see Paragraph 10.12.2), setting
r21=1
(in addition to
r10=1
and
r24=1
or
3
) activates the plant side electric heater, if
requested (regulation temperature lower than
water setpoint -r11
(°C), without waiting the time defined by
r12
.
10.5.3
DHW HEATER
Function which can be activated instead of managing the plant heater
This is an additional resource for heating the domestic hot water storage tank if the compressor alone is not capable of fulfilling the request in
a reasonable time.
If domestic hot water production lasts longer than
r16
(minutes) or if the machine blocks due to triggering of an alarm, the heater switches on.
It switches off when the unit finishes domestic hot water production (also taking into account an offset on the setpoint with parameter
r31
, as
explained in Paragraph 10.11.1).

SINGLE PLANT/DHW INTEGRATION HEATER
By configuring the DHW integration heater, it is possible to use this heater declared also as plant integration heater, setting the parameter
r15
=2
and
r24
=3.
In case of plant integration demand, the heater declared as DHW integration is activated, thus allowing to have a single integration heater for
plant, domestic hot water and plant under defrost.
10.6
INTEGRATION HEATER SELECTION MODE
The priority can be set in the order to activate the plant side and sanitary side integration heaters; specifically the configurations are:
1.
r14=0
(default), the heaters can be activated simultaneously, if present;
2.
r14=1
, the heaters can be activated, excluding one another:
2.1.
r20=0
, priority to the plant (the DHW heater only switches on if the temperature control for the plant side heater is fulfilled);
2.2.
r20=1
, priority to DHW (the plant side heater only switches on if the temperature control for the sanitary side heater is fulfilled).
10.7
CIRCULATOR MANAGEMENT WITH HEATER ON
The circulator of the heat pump can be activated when the plant and/or DHW integration heaters are active with the compressors not running
(by substitution, by alarm or by integration in bracket II or III).
-r33
= 0: The circulator of the heat pump is activated on demand of the compressors or boiler,
-r33
= 1: The circulator of the heat pump is activated if the plant heater is active.
-r33
= 2: 2: The circulator of the heat pump is activated if the DHW heater is active.
-r33
= 3: The circulator of the heat pump is activated if the plant or DHW heater is active.
The circulator switches off after post-pumping (
P02
).
10.8
BOILER ENABLING
Function which can be activated instead of managing the double setpoint.
This is an additional resource to enable the boiler in integration or substitution of the heat pump.
Define the use mode by setting the parameter
r23
:
•
r23=0
(default) boiler not used (operating priority of heaters);
•
r23=1
only boiler on plant used (operating priority of heaters);
•
r23=2
only DHW boiler used (operating priority of heaters);
•
r23=3
DHW and plant boiler used (operating priority of heaters);
•
r23=4
only boiler on plant with priority used (no heater operating priority);
•
r23=5
only boiler in sanitary with priority used (no heater operating priority);
•
r23=6
boiler on plant and in sanitary with priority used (no heater operating priority);
Define the supply of the boiler, setting parameter
r32
:
•
r32
= 0: boiler without circulator with temperature control by heat pump,
•
r32
= 1: boiler with autonomous circulator with temperature control by heat pump;
•
r32
= 2: boiler without circulator with autonomous temperature control;
•
r32
= 3: boiler with circulator with autonomous temperature control.
