MERLIN NX IP AND MST/TP VAV CONTROLLER - INSTALLATION INSTRUCTIONS

EN1Z-1076GE51 R0722

Fig. 7. Damper with 90 degree CW rotation to open

NOTE:

Mount the actuator flush with damper housing or add

a spacer between the actuator mounting surface and

damper box housing.

Fig. 8. Mounting Controller to VAV box damper housing when

actuator is not parallel to VAV box damper housing

Determine the damper ‘full opening angle’ (45, 60, or

90 degrees). In

Fig. 7

the damper is open to its fully

open position of 90 degrees.

Mounting Actuator onto Damper Shaft

MERLIN NX IP and MSTP VAV controllers can be mounted

in any orientation. However, ensure that they are mounted

in a position that allows clearance for wiring, servicing,

removal, connection of the BACnet connector, and access

to the service button.

Fig. 9. Mounting Actuator on Damper Shaft

NOTE:

The controller is not position sensitive and can be

mounted sideways or upside down. Use the drilling

template provided in box.

The MERLIN NX IP and MSTP VAV controller's inte

gral actuator does not float inside the housing there

fore it should be installed with a floating mount to

allow for non-concentric travel, which can occur with

a damper shaft that are out-of-round and/or have

asymmetrical damper shaft mounts.

If the actuator does not allow any wobble, it is likely to

bind. To prevent this, when installing the MERLIN NX

IP and MSTP VAV controllers, install it over the

damper shaft and then slide the anti-rotation bracket

underneath and into the mounting slot but not at the

very end of the slot (leave a little wiggle room).

Screw the anti-rotation bracket using two screws on

the sides of the controller. The anti-rotation bracket is

designed to be bent as needed (it has built-in bend-it-

easy slots) to accommodate difficult installation loca

tions.

Tools Required:

— Phillips #2 screwdriver for end-limit set screw adjust

ment

— 8 mm wrench for centering clamp
