General; Manual Testing The Functions; Operation With Additional Heat Only; Putting Into Operation, Operating Mode A (D And E Series) - IVT Greenline D14 Manual To Installation, Commissioning And Maintenance

General

The heating and heat transfer fluid collector systems must be filled and vented before commissioning
the heat pump. Check also that there are no leaks in the systems.
When connecting to an existing water system, check that at least two of the radiators are always
open. With underfloor heating, at least two of the circuits must be open. When connecting a fan
radiator system, start the fans in the radiators and fully open the valves to the fan radiators.
If the pump stops during testing, refer to the section headed "If something goes wrong".
Manual testing
You can manually test pumps, valves etc. by going into display 5.3 and choosing manual operation
for each function. The heat pump returns to normal operation as soon as you leave display 5.3.

Operation with additional heat only

You may want to use the additional heat in the heat pump before with the heat transfer fluid system is
ready. If the heating system is filled and vented you can activate the operation with additional heat
only. Go into display 5.4 and select "On" and the additional heat will now heat both the hot water
and heating system. Do not forget to restore this function to normal operation.

Commissioning operating mode A
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.
Heat setting Heat incr/decr can temporarily be set to 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.
Operating mode A is the factory setting so most settings are already preset so there are not many
you need to check or adjust. The only settings you need to make are Ackning the extra sensors in
display 5.13 and choosing the output of the electric heater you have fused protected the heat pump
for.
Go into display 5.4 to choose operation with additional heat
only. Note that this is not available in operating mode B
