Attention: Before connecting the room thermostat or remote timer control, remove the
A
jumper on the terminal 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 ter-
minals 5-6.
ALL CONNECTIONS TO THE TERMINAL BLOCK MUST BE WITH VOLTAGE-FREE
CONTACTS (NOT 230V).
