shown) for typical VAV application with staged reheat
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:
Contacts must be suitable for dry switching, 5 V at
10 mA. Use sealed type, gold-flashed, or pimpled
contacts.

Fig. 15. Controller wiring diagram (CLLYUB6438S shown)
for typical PWM heat and PWM peripheral heat valve
actuator
Ensure that the Configuration DIP Switch is set as shown in
Fig. 15. 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.
