Instructions

This way, every time a radiator closes completely, the Shelley 1 will turn off its outlet, but
if another radiator is open, it will turn it on shortly thereafter. This will not affect the
operation of the pump or boiler, because the maximum time in which they will be turned
off is 5 minutes during which the radiators and heating system will have enough hot
water so that there is no change in temperature.
How to wire Shelly1 to your PUMP
Connecting the Shelley 1 to a pump is easy, usually simply interrupting and switching on the
current to it.
