General; Manual Testing; Operation With Additional Heat Only - IVT GreenlineC 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 Select. Point at Normal Operation, select Adjust. Turn the knob
until the arrow points at Only Additional. Press Save. The additional heat will now heat both the hot
water and heating system. Do not forget to restore this function to normal operation.

Starting the heat pump
Connect the mains voltage to the heat pump and press the ON/OFF button on the control panel.
Rego600 measures the phase sequence so that the compressor does not go the wrong way, so if you
receive a 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.
Heating setting Heating incr/decr can temporarily be set at max. So as to avoid waiting for the heat
pump restart timer you can go in 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. On starting there may be bubbles in the sight glass for a minute or so, after which they should
disappear. Bubbles present all the time the heat pump is running are a fault symptom. They are prob-
ably 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 factory setting so most settings are already preset so there are not many you need
to check or adjust. WARNING! You must never choose another operating mode the A for the C and E
series. The only necessary settings you have to carry out is Ackning the extra sensors in display 5.13
and choosing the output of the electric heater you have fused the heat pump for.
Go into display 5.4 to choose operation with additional
heat only. Note that this is not available in operating
5.4
mode B with oil-fired boiler.
