Commissioning operating mode B
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 B. This is described further down in the text.
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.
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.

Factory setting allows the additional heat to engage when
required. In systems with only fan-assisted radiators the
additional heat can be turned off, in all other cases the
settings should be "Yes". If you choose "No", the additional
heat only engages during alarms, extra hot water and hot
water peaks.
This shows you the additional steps in and out in %. See
the description below in technical specifications.
Choose operating mode B so that Rego 600 memorises the
operation with oil-fired boiler and mixing valve.
If you have connected any of the external sensors T3 (GT3)
or T5 (GT5) you must Ackn them so that Rego 600 memo-
rises them.
When you use a mixing valve to the oil-fired boiler it is
important to set the running time of the motor. The time it
takes for the mixing valve to go from closed to fully open. It
is often marked on the mixing valve motor.
