Commissioning The Heat Pump - Operating Mode A - IVT Optima 1000 Assembly, Commissioning And Maintenance Manual

Commissioning the heat pump
Commissioning the heat pump - operating
mode A
Start the heat pump
1. Connect mains to the heat pump and press the ON/OFF switch on
the control panel. Control unit Rego 603 automatically measures the
phase sequence so the fan does not run in the wrong direction. The
air should be blown upwards through the fan. If the phase sequence
is wrong the alarm "Phase sequence error" will trip. Read more about
the alarm in the User section under the heading What to do if a fault
occurs. Disconnect the mains power to the heat pump and switch the
phases manually.
2. Activate the Installer/Service menu by pressing the Menu button until
the text Access = SERVICE is shown on the menu display.
3. Set Temp. incr. / decr. temporarily to the maximum value. To avoid
having to wait for the heat pump restart timer you can go to the menu
Fast restart of heat pump (menu 5.6) and quickly restart the pump. If
the heat pump does not start, press the Info button to see if a heating
demand exists.
4. Check the sight glass inside the heat pump during start up. Bubbles
may appear in the sight glass for a few minutes during start up. The
bubbles should then stop. When defrosting it bubbles continuously
in the sight glass. This is perfectly normal. Bubbles present when the
heat pump is running are a fault symptom. They are probably due to
insufficient refrigerant. Read more about the fault symptom in the User
section under the heading What to do if a fault occurs.
5. Make the necessary settings on the control panel. See below.
