Installation
Mounting Location Recommendations
The microprocessor module is mounted inside a molded
plastic enclosure for surface mounting. It is not weather-
proof making it applicable for indoor use only.
The Remote Human Interface Panel should be located in an
area to insure that the communication link between the
panel and the Unit or Units does not exceed 5,000 feet
maximum or pass between buildings. Refer to the “Controls
using DC Communication Links” for twisted pair wiring re-
quirements.
The low voltage AC power wiring to the Remote Human In-
terface must not exceed three (3) ohms/conductor for the
length of the run. Refer to the “Controls using 24 VAC” sec-
tion for wiring requirements.
Ambient Temperatures and Humidity Limits are as follows:
Ambient Operating Temperatures;
32 to 120 Degrees F
10 to 90% relative humidity, non-condensing
Ambient Storage Temperatures;
-50 to 200 Degrees F
5 to 95% relative humidity, non-condensing
Mounting the Remote Human Interface Panel
All mounting hardware such as; hand tools, electrical
boxes, conduit, screws, etc. are to be field provided. Refer
to Figure 2 for the location and configuration of the mount-
ing holes, electrical access knockouts in the back and ends
of the enclosure.
Mounting the Remote Panel on a 4" by 4" Electrical
Handy Box
1. Mount an electrical handy box in the wall so that the front
edge of the box will be flush with the finished wall sur-
face.
2. Prior to mounting the panel, the microprocessor module
must be carefully removed from the enclosure. To re-
move the module:
a. Lay the Remote Panel face up on a flat surface and
remove the locking screw from the right hand bottom
end of the panel.
b. Remove the recessed hinge screw from the left hand
bottom end of the panel.
c. Unlatch the door of the enclosure as if to open it, and
slide the left hand side of the door upward away from
the hinge. Lay it aside.
d. With the Key Pad visible, remove the two (2) screws
located on the right hand side of the Key Pad.
e. Carefully slide the Key Pad plate upward from the
bottom, releasing the extruded hinge pin from its
socket at the top.
f. Set the microprocessor aside until mounting is
complete.
Note: Place the microprocessor in a clean dry
location during the enclosure mounting
procedures.
3. Remove the handy box knockout in the back of the en-
closure.
Note: The top of the enclosure is marked “TOP”
with the enclosure in the correct position.
4. Align the mounting holes around the knockout in the en-
closure with the screw holes in the electrical handy box
and secure with the appropriate screws.
5. Replace the microprocessor within the enclosure as fol-
lows:
a. Verify that the jumpers for terminal blocks J-5 and J-
6 are both connected to terminals 2 and 3.
b. Slide the extruded hinge pin at the top left of the Key
Pad plate into the hole located at the top left hand
side of the enclosure.
c. Slide the bottom of the plate into place, aligning the
two (2) clearance holes with the screw holes on the
right. Install the screws but do not tighten at this time.
Note: If the two screws are not installed as called
out in the previous step, hold against the Key Pad
plate while installing the door, to prevent it from
falling out.
d. Slide the extruded hinge pin at the top left of the
door into the hole located under the bottom left side
of the display.
e. Install and tighten the hinge screw located at the
bottom left side of the enclosure.
Wall Mounting the Remote Panel
1. Prior to mounting the panel, the microprocessor module
must be removed from the enclosure. Complete step 2 in
the previous discussion, “Mounting on a 4” by 4" Electri-
cal Box”, before proceeding.
2. With the microprocessor removed, refer to Figure 2 for
the location of the mounting holes to be used for wall
mounting.
Note: The top of the enclosure is marked “TOP”
with the enclosure in the correct position.
3. Place the enclosure against the mounting surface and
mark the mounting holes.
4. Remove the enclosure and drill the necessary holes in
the surface for the appropriate fasteners. (plastic an-
chors, molly bolts, screws, etc.)
Note: Remove the necessary knockouts for the wire
or conduit entry before mounting the panel.
