Air to water heat pump controls

Controls

Greensource air to water heat pumps are controlled by a Rego 800 control unit. The unit ensures that the heat pump works efficiently when required and dictates that the hot water heating is given priority over space heating.

The control unit has a simple main “Menu” and “Advanced Menu”
