activating Heat Pump lock. If the outside temperature is below the lock temperature set,
the indoor unit (in ventilation mode) and Auxiliary Heat will be activated until the outside
temperature reaches a differential of +5ºC with regard to the set lock temperature and the
Delta Off (T ) defined in Auxiliary Heat is surpassed. When the indoor unit switches from
off
Ventilation mode to Heat Pump mode there will always be a 90-second delay.
Range: -20°C (-4°F) / 4°C (39°F) in steps of 2ºC (3.6ºF). Default: -6ºC (21ºF).

There are 3 outside Temperature scenarios:

Note: for units that do not have the "Outside Temperature" mode parameter, the outside
temperature provided by the Cloud will be taken as the default.
Note: the auxiliary heat and heat pump lock outside temperature difference will be at least
ΔT = 6ºC, and priority will be given to heat pump lock temperature over auxiliary heat lock
min
temperature.
Digital input
Allows you to activate or deactivate this function and change:
•
Activation. Allows to set the input as:
