Wiring and installation
Before attempting installation or service, ensure that all power to the circuit supplying power to the
system is disconnected / turned off at the circuit breaker. The device should be installed by a QUALIFIED
PROFESSIONAL according the manufacturer’s manual.
This controller will place between circuit breaker and your device (Spa, Pump or Heater), so for easy
wiring, you need to cut your device (Sauna, Pump or Heater) cable in 2 halves. Bring out the 2 hot lines,
neutral and ground wires of each cut end and then start with first hotline black (H1) and connect the
hotline of one half to pole 1 of connector (lose screw and put the wire under terminal) and the black
hotline of the other half to same pole in other side and repeat it again with another hotline Red and next
pole terminal. Then connect the ground green wires of both halves to easy connector with green wire and
Neutral white wires to easy connector with white wire. Please cover the contactor poles hotline pins and
easy connectors with electrical tape for safety matter. For more clarification please check the following
diagram (
for 120 VAC wiring
, use only the pole that Wi-Fi Receiver connected to it).
If you have a timer this controller can replace with timer easily. If you use your box outdoor, use silicon
strip before closing box cap and all cable glands are tight (install the box on wall in a way that main cable
glands are placed at the bottom or side of the box for rain protection) .
