Various setpoints and actual values, relay switch status data can be displayed for purpose of diagno-
sis.
• Heat pump
These lines are used to check the operating mode of the components controlled by heat pump re-
lays. The display "0" means that the associated components are currently disconnected. The dis-
play "1" means that the associated components are currently switched on.
NOTE: This information applies to relays defined as normally open contacts. For normally closed
contacts, the action is reversed.
• Setpoints and measured values
These lines allow the various setpoints and measured values for the heat pump to be viewed.
