
Use original temperature probes only; other types of components could cause poor heat pump
operation and/or cause heat pump component breakdowns.
NOTE
Digital control inputs (DIxx)
Digital signals from thermostats or other external devices can be connected to these terminals to control heat pump production
functions. Digital input supply voltage should be 24Vac/24Vdc.

Do not power external components connected to the digital inputs from the 24 Vac power supply of
the heat pump; this could cause poor heat pump operation and/or heat pump component
NOTE
breakdowns.
24Vac
24Vdc
Figure 1.15. Example of digital input connections with 24Vac / 24Vdc voltage.
Analogue outputs (AOxx)
These terminals send analogue 0-10Vdc regulation signals to modulate the control of outlet units with mixture, external auxiliary
boilers, etc. On the other hand, these connectors have a 24Vac power supply terminal to supply the modulating valve motor.
