Attention: Remove the jumper on the terminal block before connecting the room thermo-
A
stat or the remote timer control.
If wanting to connect more zones of the hydraulic system that are controlled by thermo-
stats with voltage-free contact and the timer control has to be used as a remote control for
the boiler, it is necessary to connect the voltage-free contacts of the zones to terminals 1-
2 and the timer control to terminals 5-6.
ALL CONNECTIONS TO THE TERMINAL BLOCK MUST BE WITH VOLTAGE-FREE
CONTACTS (NOT 230V).
