Attention: Remove the jumper on the terminal block before connecting the room thermo-
A
stat or the remote timer control.
To connect multiple zones of the plumbing system controlled by thermostats with voltage-
free contact and there is a need to use the timer control as a function of remote boiler con-
trols, 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).
