Fault Clearance - Techem compact V Manual De Operación

Fault clearance

Before you look for a fault on the heat meter itself, please check the following items:
Is the heating on? – Is the circulation pump running?
Are the shut-off devices fully open?
Is the pipe free (possibly clean the strainer)?
Is the dimensioning okay?
Display levels
The heat meter has two display levels - the reading level and the service level:
A long press of the button switches between the two display levels.

In the device number display, the number next to the display identifier is the first
