NOTICE

Make sure to select and install the safety thermostat according to the applicable
legislation.

In any case, to prevent unnecessary tripping of the safety thermostat, we
recommend the following:

▪

The safety thermostat is automatically resettable.

▪

The safety thermostat has a maximum temperature variation rate of 2°C/min.

▪

There is a minimum distance of 2 m between the safety thermostat and the
3‑way valve.

NOTICE

Error.

If you remove the jumper (open circuit) but do NOT connect the safety

thermostat, stop error 8H-03 will occur.

INFORMATION

ALWAYS configure the safety thermostat after it is installed. Without configuration,
the unit will ignore the safety thermostat contact.

9.3.13 To connect a Smart Grid

This topic describes 2 possible ways to connect the indoor unit to a Smart Grid:

▪

In case of low voltage Smart Grid contacts

▪

In case of high voltage Smart Grid contacts. This requires the installation of the
Smart Grid relay kit (EKRELSG).

The 2 incoming Smart Grid contacts can activate the following Smart Grid modes:

Smart Grid contact

Smart Grid operation mode

Free running

Forced off

Recommended on

Forced on

The use of a Smart Grid pulse meter is not mandatory:

If Smart Grid pulse meter is…

Then [9.8.8]
