Run two wires from low voltage thermostat through
conduit as shown. The purple wire from the valve and
the blue wire from the transformer have 1/4" (6 mm)
blade female electrical terminals, which are con-
nected by a black jumper wire. Cut the female
connections off the ends of the blue and purple wires
and strip the ends approximately 1/2" (1.3 cm). Con-
nect these 2 wires to the thermostat wires using suit-
able wire connectors.
