1.4. Control system
The heat pump is equipped with an automatic control system which manages heating
and domestic hot water production. The control system includes the built-in automation
system, the sensors attached to it, and a control panel. The control panel is used for
monitoring and changing system settings. Also error notifications are browsed and
reset on the control panel.
An optional remote control unit can also be used for browsing and changing system
data and error notifications. It can also serve as a remote temperature sensor,
providing the control system with room temperature data.
The heat pump can be remotely controlled and monitored through Modbus gateway
and remote access modules.
The system settings have been organized into menus, similar to folders on a computer.
In addition, there are various user levels in the system. The visibility of menus or
menu items depends on the user level. To access user levels other than
