NOTE: After making the connection, switch the XM controller OFF and ON to make sure that the valve is
positioned properly.
6.5. Wiring Connection of
Emerson EX3 Valve
XM678D and EX3 Connection
The EX3 valve integrates a solenoid valve with
positive shut off on the top and a stepper valve.

6.5.1. Solenoid Valve Connection

a. Verify the coil voltage of solenoid valve and ensure
that it is the same voltage with relay output.
b. Set oA1 or oA6 = E3r (solenoid coil of EX3). Any
other setting of the oA1 or oA6 parameter can
damage the solenoid valve.
c. With oA1 = E3r connect the solenoid valve to the
terminals 11-12.
d. With oA6 = E3r connect the solenoid valve to the
terminals 17-18.

NOTE: The solenoid coil will be energized
every time the temperature regulation is on and
de-energized when the temperature regulation
is off and during the standby of the controller.
6.5.2. EX3 with 24Vac Coil:
Transformer Capacity
When the coil of the EX3 is at 24Vac and a unique
transformer is used to supply both the controller and
the coil of the valve, a 40VCA transformer must be
used like TF40D. Any transformer with lower
capacity can damage the valve or the controller.
