Putting Into Operation, Operating Mode C (D Series Only) - IVT Greenline D14 Manual To Installation, Commissioning And Maintenance

Commissioning operating mode C
Connect the mains voltage to the heat pump and press the ON/OFF button on the control panel.
Rego 600 measures the phase sequence so that the compressor does not run in the wrong direction,
so if you receive an phase sequence alarm the main supply is cut to the heat pump and two of the
phases are shifted.
Press "Menu" for 10 seconds to come into the Installer / service menu. I/S should be visible at the
top right hand corner.
Go into display 5.1 and choose operating mode C.
Heat setting Heat incr/decr can temporarily be set on max. To avoid having to wait for the heat pump
restart menu you can go to display 5.6 and quick start the heat pump. If the pump does not start,
press "Info" to see what the reason is. When the heat pump starts, check the sight glass in the heat
pump. When starting there may be bubbles in the sight glass for a minute or so, after which they
should disappear. If there are bubbles present all the time the heat pump is running, this is a fault
symptom. They are probably due to air in the collector hose or insufficient heat transfer fluid.
Check that the operational condition of the heat pump corresponds to the information supplied in the
Info menu.
There are always some settings you have to check or adjust and some you might need to change if
they require another setting than the factory setting.
