3. Remote start/stop

There is the possibility of connecting an external switch to control the ON/ OFF of the

system. It is a zero-voltage contact, that must be connected to the terminals 7-7.

If the installer does not use an external switch, jumper connect the terminal blocks 7-7. In

this case, the module will be switch on through the thermostat (see section 10. Comminisioning).
