Industrial inverter air/water heat pumps with axial fans

- r23=5 boiler used only for DHW hot water with priority (no intervention priority for electric heaters);
- r23=6 boiler used on both DHW and plant sides with priority (no intervention priority for electric heaters);
Settings of the parameter “ r32 ” for boiler equipment:
•
r32 = 0: boiler without a circulating pump with thermoregulation to be performed by the heat pump unit.
•
r32 = 1: boiler equipped with an independent circulating pump with thermoregulation to be performed by the heat
pump unit.
•
r32 = 2: boiler without circulating pump with independent thermoregulation.
•
r32 = 3: boiler equipped with a circulating pump with independent thermoregulation.

8.3 ACTIVATION OF AUXILIARY ELECTRIC HEATER AND BOILER DURING THE JOINT/IN SUBSTITUTION
OPERATION TO THE COMPRESSOR
The available auxiliary systems for the joint operation or substitution operation are as below:
- Boiler
- Plant auxiliary electric heater
- DHW auxiliary electric heater
Considering the heating and sanitary mode of operation, you have 4 types of operation:
Heat pump

r22=7
r28=-7
r08=-16

Heat pump + [Boiler and/or electric heater]
[Boiler and/or electric heater]
[Heat pump and/or electric heater]
IN JOINT OPERATION I
IN JOINT OPERATION II
IN SUBSTITUTION OPERATION
For the models UMHPI V the parameter r08 =-20°C
When changing the values of the parameters r22 , r28 , r08 , you have to respect the following condition: r22 ≥ r28 ≥ r08 .
You can remove the zone corresponding to the “ in joint operation I ” just by putting r22=r28 ; you can also remove the zone
corresponding to the “ in joint operation II ” by putting r28=r08 ; and hence you can remove both “ in joint operations I and II ” just
by setting the three parameters as the following configuration r22=r28=r08 .
8.3.1 OPERATION IN HEAT PUMP MODE
Normal operation of the heat pump in which the electric heaters and-or the boiler will be activated only if the heat pump goes
into error-alarm.
8.3.2 IN JOINT OPERATION (AREA I)
If the outdoor air temperature is included between r22 and r28, the compressor operates in synergy with the auxiliary electric
heaters during winter and domestic hot water (sanitary) mode.
In this operation area, the heat pump will start at the beginning and then the plant side auxiliary electric heaters will operate after
a period of time given by
r12 (in minutes) and after r16 (in minutes) the DHW auxiliary electric heaters will start operation.
The activation priorities are defined by the parameters r14 , r20 , r23 and r24 .
The operation becomes normal if the temperature increases above the value given by r22 + 1,0°C.
Note:
In the joint operation, the temperature of the boiler is controlled by the water temperature remote sensor of the plant circuit (if
enabled), particularly if the temperature measured by the remote sensor is less than the setpoint
Hea , the boiler will be activated,
and then will be deactivated when the measured temperature by the remote sensor is greater than setpoint Hea .
The boiler will be managed by the outlet temperature sensor of the heat pump if the water plant circuit remote sensor is not
enabled.
