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

Commissioning the heat pump
Commissioning the heat pump - operating
mode B
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.
2. Activate the Installer/Service menu by pressing the Menu button until
the text Access = SERVICE is shown on the menu display.
3. Set the heat pump for operating mode B. See more information below.
4. 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 heat pump.
If the heat pump does not start, press the Info button to see if a heating
demand exists.
5. 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. 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 manual under the heading
What to do if a fault occurs.
6. Check that the operating status of the heat pump corresponds to the
information supplied in the Info menu.
7. Make the necessary settings on the control panel. See below.
Menu displays you must always check
1. Set the heat pump for operating mode B. The control unit Rego 603
needs to save the settings required for operation with electric/oil-fired
boiler and mixing valve.
2. Confirm connected external sensors. If T3 (GT3) or T5 (GT5) have
been connected, you must confirm these so the control unit knows
they are installed. The displays presented by the sensors are only
shown if the sensors have been confirmed.
