TROUBLE SHOOTING
The control panel for the air source heat pump is located under
a secure cover on the right hand side of the machine. Access
should only be required in the event of a problem as the
installer will set the water flow temperature appropriate to the
heating - see diagrams.
•
The red mains lamp (B) confirms that mains power is
connected
•
The red programmer live lamp (D) confirms that the unit is
connected to the heating system controller
•
The space heating temperature controller (A) is used to
adjust the return water temperature from the space heating
system. For maximum economy, this should be set to the
lowest acceptable level. The setting is adjusted by first
pressing and then releasing button P followed by pressing
the up or down arrow buttons to display the required
temperature. After 5 seconds the display will revert to the
actual water temperature
•
The amber fault lamp (F) indicates a possible problem in the
system. This may be cleared by the manual reset of the high
pressure switch. However, if this does not clear the fault, you
should contact your service engineer.
•
The green defrost lamp (C) is illuminated when the heat
pump evaporator is defrosting.
