Transformer T1
The electric control system is built up around the control board A1 (Pic. 3.10) which is divided
into two systems, a 5 VDC system on one side to supply the sensors B8, B4, B6, B1, B9, B7 and
on the other side 24 VAC, which supplies the actors (contactor, relay, solenoid valve).
The transformer T1 (Pic. 3.9) supplies the system with 24 VAC and 8 VAC.
