base B from the front panel C.
• Run the two wires, coming from the terminal block
or other Open Therm (OT) terminal present in boiler
A, through the hole in the base B to be mounted on
the wall.
• Connect the two wires to terminals D of the front
panel C.
• Secure base B to the wall using the plugs and screws
supplied with the accessory.

IMPORTANT
If fault E88 appears on the boiler display, there is a communication problem between the
boiler card and the control unit. Avoid placing cables near sources of heat, high voltage
and magnetic fields.
