Pump and valve exercising
The pumps are exercised to prevent them from "jamming" following long-term downtime. Exercising is active
when the pumps are idle, if the downtime is due to the pumps being turned off by the ECO function, i.e. it is
warmer outside than the ECO mode's set outT.
Exercising parameters can be set, for period time and duration. The factory setting is about 30 seconds running
time, 1 time/week.
The pumps must have been idle for at least one hour before they can be exercised.

Save and reset start-up settings and factory settings
The first time IQHeat is started, the Service settings and Factory settings are the same.
After adjustment of the plant-specific parameters such as heating curve, time programs and the like, it is useful
to save these settings for later use if something goes wrong.
The factory settings cannot be changed and they can only be restored from the service level, while the start-up
settings can be restored at end user level.
