for typical PWM heat and PWM peripheral heat valve
actuator
Ensure that the Configuration DIP Switch is set as shown in
Fig. 17. Switches 1 through 3 set the timing of the ML7984B
valve actuator to match the controller outputs (min. 0.1 sec;
max. 25.6 sec). Switch 4 determines the action of the actuator
(OFF = direct acting, ON = reverse acting).
NOTE 1: Earth ground wire length should be held to a
minimum. Use the heaviest gauge wire available,
up to 14 AWG (2.0 mm
2
), with a minimum of 18
AWG (1.0 mm
2
), for earth ground wire.
NOTE 2: Turn power OFF before setting the DIP switches.
NOTE 3: Ensure that all transformer / power wiring is as
shown. Reversing terminations will result in
equipment malfunction.

Fig. 18. Controller wiring diagram (CLLYUL6438S shown)
for typical AHU application
NOTE 1: Earth ground wire length should be held to a
minimum. Use the heaviest gauge wire available,
up to 14 AWG (2.0 mm
2
), with a minimum of 18
AWG (1.0 mm
2
), for earth ground wire.
NOTE 2: Analog outputs from sensor are 4…20 mA signals.
A 499 Ω 1% tolerance (or better) precision resistor
is required to drive this and other 4…20 mA signal
devices. Place this resistor as close as possible to
the driven device.
