Yes they can be plugged into a timer. Operating with the provided 3 pin plugg they can be put into a timer; as the plugg is EC certificated there is no risk! Calortec radiators have on some models a pilot wire, these are frequently used on a program station as you have in France on almost all electric installations. Just for your information Calortec has also radiators whom can be programmed by a real program station compleetly wireless! Again now that each and every radiator has their own thermostat and can operate by themself, the program station is a helpfull device to operate in an automatic way.
