from factory and can’t

short description of each

turn the electrical re-heater
battery on or off. Activated

function. The function
overrides current set fan
speed settings and runs in
forced mode according to

Ext/Force run
. Choose
between Low, Nom and

based on the signals from
an impulse-switch. If a
standard switch is used,
the countdown of the set
time starts when the switch
is switched off.

DI7: Switching on this
input decreases the supply
air temp set point with

speed to min. Fan speed
settings are done when
