Attention
: Before connecting the
room thermostat
or
remote timer control
, remove the jumper on the ter-
minal block.
To connect more zones of the hydraulic system controlled by thermostats with voltage-free contact, and the
timer control has to be used as a remote control for the boiler, the voltage-free contacts of the zones must be
connected 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).
