Normal operation:
The heat pump works normally.
Forced shutdown:
The heat pump switches off, autonomously, for a maximum of 2 hours during the day.
It is possible to display the switch-off time through the "Counters".
The counter resets at midnight.
Mode 1:
In this mode the set point of the ACS is increased thus allowing to have a higher thermal energy stocked
into the boiler.
Also works on the system water hysteresis on heating phase, cooling phase and on the ACS.
Mode 2:
In this mode the set point of the ACS is increased thus allowing to have a higher thermal energy stocked
into the boiler.
In the same way, the set point is increased during heating phase, even without the request from the system
terminals; the set point is decreased during cooling phase, even without the request from the system terminals.
Also works on the system water hysteresis on heating phase, cooling phase and on the ACS.
6.4 - CHECK OF THE CIRCULATION PUMPS
During installation, the operation of the circulation pump can be forced for 15 minutes from the window on
the control display "Pumps"; in that way, air bleeding is eased in the final filling phase of water in the system.
The circulation pump can work in different modes depending on the needs of the system:
- Continuous operation of the pump (parameter ADDR221=OFF=0)
- Switching off upon reaching the desired temperature (parameter ADDR221=ON=1) and sampling every
ADDR237 minutes for one minute (parameter ADDR237=10 minutes, the pump will activate for one minute
every ten minutes).
When the system is in stand-by or with fulfilled set point, the anti block function of the system and DHW circuit
pumps is present; setting the parameter ADDR221=ON=1, the pump is activated every ADDR222 hours for
a time equal to ADDR223 seconds). The parameters above can be set in the window Service.
6.5 - AUXILIARY EXTERNAL HEAT SOURCE MANAGEMENT
In heating or domestic water production mode, set the parameter ADDR226=ON=1 and, if external ambient
temperature is lower than ADDR227 degrees centigrade, the control will provide for the replacement of the
heat pump with the activation of an output for enabling of an external heat source.
7 - USE
7.1 - PRODUCTION OF DOMESTIC HOT WATER
With SHERPA AQUADUE TOWER, thanks to a water/water integrated in the internal unit heat pump, it is possible
to produce domestic hot water at high temperature (up to 75°C) without the use of electric heaters, in parallel with
the conditioning function and independently from external air temperature. The production of domestic hot water,
