Controlling an immersion heater or towel
rail or other electrical devices
Installation
Link the mains cables to the Electric Switch as shown in the diagram. Be
aware, the first diagram assumes the switching of mains power NOT a volts
free system. The switch can also be used to switch volts free (useful for
curtains and door operators amongst others) as shown in the second
diagram. In such installations, mains live should NOT be connected to the
COM terminal; the volts free connections should connect to COM and NO
only. Note that the switch will still require mains power to the L and N
terminals for it to operate volts free.
The Electric Switch can be used to remotely turn on/off any connected
electrical devices up to 3000W. It can be set to operate thermostatically or as
an on/off relay only (see device setup section for details).
Any connected loads
must
be resistive loads such as immersion heaters,
towel rails, electric heaters, lighting circuits or electric gates.
The switch is not
suitable for switching inductive loads, such as contactors, unless used with
an appropriate surge protector
to prevent damage caused by electrical
surges
.
