NOTE
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
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.
Figure 4.5.
Example of voltage-free digital input connections.
NOTE
24Vac external equipment can be connected directly from the supervisor, and connected equipment
as a whole must not exceed 36VA or 1.5A. Failure to comply with these ranges could cause poor
heat pump operation and/or heat pump component breakdowns.
Figure 4.6.
Example of digital input connection with 24Vac voltage.
