Setting The Offset Temperature; Restoring The Factory Settings; Intended Use; Troubleshooting And Maintenance - eQ-3 L Mode D'emploi

19. Setting the offset temperature

Since the temperature is measured at the radiator, it can
be colder or warmer at another location in the room. In or-
der to equalise this, a temperature offset of +/- 3.5 °C can
be set. If for example 18 °C is measured instead of the set
20 °C, then an offset of -2.0 °C is to be set.
To set the offset temperature proceed as follows:
• Press the Menu key longer than 3 seconds.
• Select the „OF" menu item with the selector dial and con-
firm with the OK key
• Turn the selector dial for as long as necessary until the
desired temperature appears.
• Confirm with the OK key.

20. Restoring the factory settings

The status of the programmable radiator control unit can
be manually restored by means of a reset to that when ori-
ginally supplied. This means that all the manually perfor-
med settings are lost.
Follow these steps:
• Hold the Menu key pressed down for longer than 3 se-
conds.
• Select the „RES" menu item with the selector dial and con-
firm with the OK key. „CFM" then appears in the display.
• „CFM" then appears in the display.
• Confirm with the OK key.

21. Intended use

The programmable radiator control unit is used to control
a conventional radiator valve. Only operate the device in
inside rooms and avoid the influence of moisture, dust and
sunlight or external heat radiation. Any type of use other
than that described in these operating instructions does
not comply with the intended use and leads to automatic
exclusion from warranty and liability claims. This also ap-
plies in the case of conversions and modifications. The
devices are solely intended for private use.

The programmable radiator control unit performs a
decalcifying run once a week on Saturday at 12:00 to
protect against calcification of the valve. During this
„CAL" appears in the display.
