Manual Test Run Of The Heat Pump - IVT Optima 1000 Assembly, Commissioning And Maintenance Manual

Read the alarm timer
The function gives you information about an alarm. If the heat pump has
stopped, a countdown starts from 60 minutes (3600 seconds). When this
time has elapsed and the alarm has not been rectifi ed, the additional heat
starts so that the house will not be cold and to produce hot water.
Read the start delay
The function shows the time remaining until the heat pump starts again
after a previous stoppage. The heat pump will not start when there is no
requirement.
Read delayed mixing valve opening
The function shows the time remaining before the mixing valve opens after
the heat pump has started. The menu display is only shown for operating
mode B.
Read delayed oil-fi red boiler stop
The function shows the time remaining before the electric/oil-fi red boiler
stops after there is no longer a need of additional heat. When the boiler has
stopped producing heat, the additional heat timer is restarted. The menu
display is only shown for operating mode B.
Setting the additional heat timer
The function gives you the possibility to set the time that should elapse
before the additional heat may start if the heat pump cannot produce the
heat on its own. On delivery the additional heat timer is set to 60 minutes.
60 minutes is recommended when electricity is used for additional heat,
and 120 to 180 minutes is recommended when an oil-fi red boiler is used.
Return to factor y settings
If you regret your settings you can return to the factory settings in menu
12. If you are in Customer level 1 or 2 when you select Return to factory
settings, only the settings made on Customer levels 1 and 2 are reset. If you
are on the Installer / Service level when you select Return to factory settings
only the displays accessible from Installer / Service level are reset.

Manual test run of the heat pump

Instead of starting the heat pump directly in normal mode, you can
manually test run the pumps and valves. This is recommended since in this
mode you can easily locate any possible faults. In the menu display Manual
operation of all functions (menu 5.3) you can run all functions manually.
Press the Select button to start test operations. When you exit from the
menu display the heat pump returns to normal mode.
