4. PURPOSE AND CONTENTS OF THE MANUAL
The manual is intended to provide the essenal informaon to congure the controller of the units.
It is addressed to the installer and operators of the appliance and it enables them to use the equipment eciently, even if they do not have any
previous specic knowledge of it.
Not all of the funcons described can be acvated and/or selected at the same me. Contact our headquarters for further informaon.
The manual describes the machine at the moment it was sold. It must therefore be considered adequate with respect to the state-of-the-art in
terms of potenality, ergonomics, safety and funconality.
The company also performs technological upgrades and does not consider itself obliged to update the manuals of previous machine versions
which could even be incompable. Therefore make sure to use the supplied manual for the installed unit. Contact our headquarters in case of
updates or doubts.
The user is recommended to follow the instrucons contained in this booklet, especially those concerning safety and roune maintenance.

The regulator allows you to modify the set-point by adding up the value according to the temperature of the outdoor air probe. To use this func-
on, edit the values from parameter b08 to b14 following the informaon below (edited by the installer).
Parameters of regulator PAr -> rE
• b08 enable = 1/disable=0 dynamic set-point.
• b09 = maximum cooling oset.
• b10 = maximum heang oset.
• b11 = Cooling outdoor temperature seng.
• b12 = Heang outdoor temperature seng.
• b13 = Cooling temperature delta.
• b14 = Heang temperature delta.

Another type of adjustment allows you to edit the setpoint by adding (or subtracng) a value depending on the 0-10V input (if enabled). To
enable the funcon, set H22=40, and, if appropriate, edit the value of the parameter b15 (range 0-10), keeping in mind that if b20=0, 0-10Volt
input, if b20=1, raometric input.
-b20 = 0 with input at 0 Volt, the current setpoint: (Coo/Hea) seng – b15/2
-b20 = 0 with input at 5 Volt, the setpoint will be that set (Coo/Hea)

7. CIRCULATOR
The circulator of the heat pump can be set in the following operang modes:
• operaon on call by temperature controller
• operang on call by temperature controller with periodic acvaon;
• connuous operaon (default);
The circulator is switched o immediately if:
• There is a manual reset pump block alarm, including the ow switch alarm;
• With remote input in standby or o, the pump (if running) is always switched o with a delay equal to P02 in tenths of a minute (default
P02=2)
The circulator can be congured with P03 to operate independently from the compressor or on call.

Switching from ulity water to domesc hot water, the working probe changes from “water outlet probe” to “DHW tank probe”. Switching from
winter mode to sanitary mode, the compressor does not switch o and is brought to the maximum frequency established by the controller,
whereas switching from summer mode to domesc hot water, the compressor is switched o and waits a safety me.
Defrosng is always carried out in winter mode on the ulity side, and never on the domesc hot water tank.
NOTE:
-If H10 = 1/3/5. Switching o the unit by remote control (remote on-o, see paragraph 10.4.1) does not aect domesc hot water operaon. The
unit goes to priority sanitary mode just powered on. The display on the machine shows the temperature detected by the probe inside the DHW
tank. When the sanitary cycle has nished, the display goes back to showing the water outlet probe temperature.
If the remote ON-OFF digital input (terminals 15.1 / 15.2) is open, with sanitary funcon enabled (H10=1 and H20=6), the wording “SAN” will
appear on the machine display. When the sanitary cycle has nished, the display goes back to showing “E00” indicang that the remote ON-OFF
contact is open.
-If H10 = 2/4/6, the remote on-o funcon disables domesc hot water producon and operaon of the heat pump in hean and cooling mode,
system side.
MEMORISING THE PROBE IN HEATING MODE
Switching from ulity water to domesc hot water, the working probe changes from “water outlet probe” to “DHW tank probe”. For this reason,
in heang mode, before entering sanitary mode, the last value read by the heat pump delivery probe is stored.
When sanitary temperature control is fullled, the system side temperature of reference goes back to that previously stored. The memory
funcon interrupts:
• when the temperature read by the probe becomes lower than the stored value;
• or when a me equal to b06 seconds (default b06 = 45) has elasped.
HEATING MODE ON DHW STORAGE TANK
If the parameter H130=1, the machine exploits the DHW storage tank even for central heang. In these condions, the outlet of the DHW valve
is also enabled during operaon in heang mode and not only in sanitary mode. The valve is deacvated during defrosng and in cooling mode.
When H130=1, the DHW integraon heater can be enabled also to act as system integraon heater: to do this, set r10=1 e r15=2 (for other r15
sengs see Paragraph 10.6.3); furthermore no digital output must be set as system integraon heater.
INSUFFICIENT HEAT EXCHANGE IN A DHW SYSTEM
During DHW producon, if the heat pump ow probe detects a temperature higher than 60°C, the DHW valve output is de-energised (DO6), and
the value of the DHW probe at this me is recorded (Tsan,set).
-if the operaon is San or Cool+San the compressor is stopped.
-If the operaon is Heat+San, the system evaluates for b06 seconds whether there is a demand for heang from the system. If the system re-
quires it, the compressor connues to work on the system, otherwise it is switched o.
-If the DHW resistor is present (e.g. DO3, H81=26), r15 = 0 or 1 and r24=2 or 3 it is acvated unl the DHW setpoint detected by the DHW probe
is met (and any oset).
The compressor restarts when the ow temperature of the heat pump falls below 60°C again and the temperature measured by the DHW probe
is lower than Tsan,set - 4°C.

SINGLE PLANT/DHW INTEGRATION HEATER
By conguring the DHW integraon heater, it is possible to use this heater declared also as plant integraon heater, seng the parameter r15=2
and r24=3.
In case of plant integraon demand, the heater declared as DHW integraon is acvated, thus allowing to have a single integraon heater for
plant, domesc hot water and plant under defrost.
INTEGRATION HEATER SELECTION MODE
The priority can be set in the order to acvate the plant side and sanitary side integraon heaters; specically the conguraons are:
1. r14=0 (default), the heaters can be acvated simultaneously, if present;
2. r14=1, the heaters can be acvated, 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 fullled);
2.2.r20=1, priority to DHW (the plant side heater only switches on if the temperature control for the sanitary side heater is fullled).
CIRCULATOR MANAGEMENT WITH HEATER ON
The circulator of the heat pump can be acvated when the plant and/or DHW integraon heaters are acve with the compressors not running
(by substuon, by alarm or by integraon in bracket II or III).
-r33 = 0: The circulator of the heat pump is acvated on demand of the compressors or boiler,
-r33 = 1: The circulator of the heat pump is acvated if the plant heater is acve.
-r33 = 2: 2: The circulator of the heat pump is acvated if the DHW heater is acve.
-r33 = 3: The circulator of the heat pump is acvated if the plant or DHW heater is acve.
The circulator switches o aer post-pumping (P02).

Funcon which can be acvated instead of managing the double setpoint.
This is an addional resource to enable the boiler in integraon or substuon of the heat pump.
Dene the use mode by seng the parameter r23:
• r23=0 (default) boiler not used (operang priority of heaters);
• r23=1 only boiler on plant used (operang priority of heaters);
• r23=2 only DHW boiler used (operang priority of heaters);
• r23=3 DHW and plant boiler used (operang priority of heaters);
• r23=4 only boiler on plant with priority used (no heater operang priority);
• r23=5 only boiler in sanitary with priority used (no heater operang priority);
• r23=6 boiler on plant and in sanitary with priority used (no heater operang priority);
Dene the supply of the boiler, seng 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.
