Analogue inputs (AIxx)
These terminals are used to connect external temperature probes. Only passive NTC temperature probes can be connected, so
cable connection polarity is not important.
If necessary, use extension cables with a maximum length of 50 m and a minimum diameter of 0.75 mm
120 m) it is recommended to use cable with a section of 1.5 mm

Use original temperature probes only; other types of components could cause poor heat pump
operation and/or cause heat pump component breakdowns.
NOTE
NTC
Digital control inputs (DIxx)
Digital signals (open/closed contact) from thermostats or other external equipment can be connected to these terminals to control
the sources.

Take special care with the working voltage of each digital input; improper handling could cause poor
heat pump operation and/or heat pump component breakdowns. Some digital inputs require
NOTE
voltage-free signals, while others require 24Vac signals. 24Vac signals are sent from their own
terminal block strip.

Do not mix voltage-free and 24Vac signals.
