Industrial inverter air/water heat pump with axial fans

The below Table (6) shows the behavior of the auxiliary electric heaters of both sanitary and plant in all cases where the unit is
operating.
TABLE 6. OPERATION OF AUXILIARY ELECTRIC HEATERS
N° MODE OPERATION AUXILIARY ELECTRIC HEATER OF PLANT AUXILIARY ELECTRIC HEATER OF SANITARY
1 HEAT+SAN HEAT It works as indicated in the TABLES 1,2,3 and 4.
During "HEAT+SAN" operation, the sanitary
thermoregulation by default will have priority
over that of the plant side, so if the
thermoregulation is required, the unit will start
the "SANITARY" mode operation and the
auxiliary electric heater of sanitary side behaves
as described in the TABLES 1 , 2, 3 and 4.
2 HEAT+SAN SANITARY
Only if the following 3 conditions are fulfilled:
- Output for auxiliary electric heater of plant
side is configured;
- r24=1/3;
-
the remote sensor of water plant
temperature is installed and configured
;
the auxiliary electric heater of the plant is
active in the below cases:
-
after
r12
minutes from the beginning of its
counting when activated previously in
“HEAT” operation mode (see line N°1);
-
if not already activated its counting in the
previous "HEAT" operation mode, after r12
minutes from the thermoregulation
requirement.
- In DHW (sanitary) mode, if the remote sensor
is not set, the auxiliary electric heater of the
plant will be disabled or its eventual counting
will be stopped.
- If the "on-off remote contact" turns to the
open state, the auxiliary electric heater of the
plant will turned off.
It works as indicated in the TABLE 1,2,3 and 4.
3 COOL+SAN SANITARY Not available. It works as indicated in the TABLE 5.
4 COOL+SAN COOL Not available. Not available.
9.10.6 AUXILIARY SYSTEMS OFFSET MANAGEMENT
During the joint operation or in substitution operation, for boiler and/or auxiliary electric heaters (depending on your resources
and on the selected priorities) it is possible to determine a set-point in heating or sanitary greater than the one of the heat pump.
This is achieved by setting a temperature offset for the set point:
- r29 : Temperature offset for boiler and electric heaters of the plant for the first set point ( G02 );
-
r30
: Temperature offset for boiler and electric heaters of the plant for second set point (
G05
);
- r31 : Temperature offset for boiler and sanitary electric heaters ( G03 ).
In this way, the heat pump will stop when achieving the set-point ( G02 , G03 , G05 ) and the temperature difference can be
supplemented by the boiler and/or electric heaters according to the selected temperature offset.
9.11 DOUBLE SET-POINT MANAGEMENT
The double set-point function introduces a second working set-point of the plant side (in both cooling and heating mode).
It is possible to configure in the user terminal block “GI” a digital input allowing the transition from the first to the second set-
point and vice versa.
