Chillers and Inverter Air/Water heat pumps with axial fan
additional resource for heating in case the compressor cannot meet the set in a reasonable time. The resistor controller only operates in heating
mode and if r10 = 1.
To define how the integration resistors are to be activated, parameter r24 must be set:
• r24 = 0 for integration resisitors not used;
• r24 = 1 for use of system integration resisitor;
• r24 = 2 for use of sanitary integration resisitance;
• r24 = 3 for use of both the system integration resistor and the sanitary integration resistor.
21.1 SYSTEM RESISTENCE
The system resistance must be connected to the digital output DO2E and can be configured by setting parameter H87 = 22.
If the regulation temperature remains lower than the hot water set-point Hea – r11 (°C) the integration resistor is activated according to the
operation of the machine in the combined or replacement bands.
The resistor is also activated if the control temperature remains below the water set-point Hea – r11 (°C) and the machine is in lockout due to
the intervention of an alarm. It switches off when the machine exits the alarm block.
Setting r21 = 1, during the defrost cycle, if required (temperature lower than Hea - r11), the system resistor is activated without waiting for the
time defined by r12.
The resistor switches off when the set-point is reached (also taking into account any offset set with parameters r29 or r30).

21.2 SANITARY RESISTANCE
This function can be activated as an alternative to the system integration resistance. The DHW resistance must be connected to digital output
DO3 and can be configured by setting parameter H88 = 26, in addition the DHW function must be active.
The resistance is activated if the production of domestic hot water lasts longer than r16 (minutes) or if the machine goes into lockout due to
the intervention of an alarm. It switches off when the machine finishes DHW production (also taking into account any offset on the set-point set
with parameter r31).

21.3 INDIVIDUAL SYSTEM/HEALTH INTEGRATION RESISTENCE
Configuring the DHW resistance it is also possible to use it as a system resistor, by setting the parameter r15 = 2 and r24 = 3 .
In this way, in the event of a request for system integration, the resistance declared as DHW integration is activated, thus making it possible to
have a single integration resistance for the system, DHW and defrosting.
21.4 INTEGRATION RESISTANCE SELECTION MODE
The resistors can be activated simultaneously if
r14 = 0
(default), otherwise the priority of the order of activation of the system-side and DHW-
side integration resistors can be set, in particular the configurations are:
• r14 = 1 for resistance activation in exclusion of each other;
• r20 = 0 for system priority (the domestic heating element is activated only if the system-side thermoregulation is satisfied);
• r20 = 1 sanitary priority (the system resistor is activated only if the thermoregulation on the sanitary side is satisfied).
21.5 CIRCULATOR MANAGEMENT WITH ACTIVE RESISTANCE
The circulator of the heat pump can be activated when the plant and/or DHW integrations resistences are active with the compressors not run -
ning (by substitution, by alarm or by integration in bracket II or III):
• r33 = 0 for activation on request of the compressors or for any boiler request.
• r33 = 1 for activation with system resistance active.
• r33 = 2 for activation with sanitary element active.
• r33 = 3 for activation with system or sanitary resistor active.
The circulator switched off after post-pumping (P02).
21.6 BOILER ENABLING
This function can be activated as an alternative to the SANITARY RESISTANCE function.
This is an additional resource to enable the boiler in integration or substitution of the heat pump. The relative digital output for enabling the
boiler is DO7, it can be configured by setting parameter H88= 29.
Define the mode of use by setting parameter r23:
• r23 = 0 (default) for boiler not used (priority of resistor intervention);
