NOTE:
Terminals 16 and 17 (TA) are bridged together to allow system pump operation if a room thermostat is not
employed.
WARNING:
When a room thermostat is used, remove the wire bridge and control for a correct wiring of the room
thermostat. If the system pump doesn’t work, control for a faulty room thermostat. Check that the room
thermostat have a galvanically insulated contact from the rest of the thermostat circuitry.
The door microswitch is pre-mounted on its support; the only thing that must be done is connecting the two
wires to terminals 18 and 19.
