INTRODUCTION
The continental series is an attractive, low prole
enclosure that incorporates a precision temperature
sensor used to monitor room temperatures. Additional
options are available that include set-point adjustment,
manual override, fan speed, handset communication
port, and an LCD.
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning the device. Failure to follow these
instructions may result in product damage. Do not use in an explosive or hazardous environment, with
combustible for ammable gases, as a safety or emergency stop device or in any other application where
failure of the product could result in personal injury. Take electrostatic discharge precautions during
installation. Do not exceed the device ratings.
MOUNTING
The temperature sensor mounts directly on a wall or onto an electrical wall box. For the most accurate
results, the unit should be mounted on an inside wall to a wall box ve feet from the oor. Do not mount
the sensor near doors, opening windows, supply air diusers, or other known air disturbances. Avoid areas
where the sensor is exposed to vibrations or rapid temperature changes.
The cover is hooked to the base at the top edge and must be removed from the bottom edge rst. Use
a small Phillips screwdriver to loosen the security screw as shown in Figure 1. (Complete removal is not
required). Use a screw driver to carefully pry each bottom corner if necessary. Tip the cover away from the
base and sit it aside as shown in Figure 2.
SENSOR ONLY
Feed at least 6 inches of wire through the wall and out of the junction box and feed connection wires
through the center hole on the backplate. Secure the backplate to the wall or electrical box with suitable
screws (not supplied) as shown in Figure 3. The mounting holes in the backplate allow for up, down, and
side to side movement to compensate for unlevel electrical box installation.
Retrieve the sensor with clip. Turn the clip over and remove the
backing from the clip to expose the adhesive back. Stick the
clip on a smooth surface of the backplate. See Figure 4.
Make wire connections as per the Wiring Illustrations on Page 2.
Re-install the decorative cover by placing the top of the cover
into the cover holder on the top of the backplate and snapping
the bottom into place as shown in Figure 7. Tighten security
screw with a screwdriver.

WIRING
• If LCD is present, deactivate the 24 Vac/dc power supply until all connections are made to the device to
prevent electrical shock or equipment damage. Follow proper electrostatic discharge (ESD) handling
procedures when installing the device or equipment damage may occur.
• Use 22 AWG shielded wiring for all connections and do not locate the device wires in the same conduit
with wiring used to supply inductive loads such as motors. Connect the cable shield to ground at the
controller only. Make all connections in accordance with national and local codes.
• Connector layout is shown in Figure 9. The diagram shown includes all options, if an option is not
ordered, the connector will not be present.
WITH PCB
The PCB must be removed from the base to access the mounting
holes. Follow usual anti-static procedures when handling the PCB and
be careful not to touch the sensors. The PCB is removed by pressing
the enclosure base to unsnap the latch near the bottom edge, then
the PCB can be lifted out of the base as shown in Figure 4.
Set the PCB aside until the base is mounted on the wall. For added
protection, place the PCB in the supplied anti-static bag.
Mount the base by screwing it to an electrical box or directly to the
wall as shown in Figure 5.
After the base is screwed to an electrical box or the wall using the appropriate holes, remove the PCB from
the anti-static bag, feed connection wires through center hole and place the top of the PCB into the PCB
holders on the backplate and snap the bottom of the PCB into place as shown in Figure 5.
Make wire connections as per the Wiring Illustrations on pages 2 and 3. Re-install decorative cover by
placing the top of the cover into the cover holder on the top of the backplate and snapping the bottom
into place as shown in Figure 7. Tighten security screw with a screwdriver.

If the unit has the LCD option then the scale can be set to either °C
or °F via the Scale jumper. See Figure 10. If he unit is also equipped
with the backlight option it can be enabled or disabled via the
Backlight jumper. The LCD display can be calibrated by adjusting
the LCD ADJ pot.
MANUAL OVERRIDE/OCC IN
The optional override switch output is a dry-contact and is available
on the SWITCH + and SWITCH - terminals. It is typically connected
to a low-voltage digital input on the controller to indicate room occupancy or override when the button
is activated.
If the override switch is ordered with the optional LCD, also included is the OCC IN. The OCC IN terminal
is a digital input that controls the OCC segment on the LCD to indicate an occupied condition. It can be
connected to a 0-5V digital signal or a dry contact signal. This is usually an active low input signal and
requires that the OCC IN terminal be shorted to COMMON to activate the input.
LED
The LED is typically used as indication as when manual override has been selected. It is available on the
LED+ and LED- terminals and requires 5 Vdc to power. The LED option is not available when LCD installed
FAN SPEED SWITCH
The 5 position speed fan speed has a resistance output signal on the FAN + and FAN - terminals and has
dierent resistances for each position 5 positions (Auto, O, Low, Mid, High).
EXTERNAL JACK
The external jack is internally connected to a 4-pin terminal block labeled 1, 2, 3, 4 and excepts a 4 pin
molex connector for remote communication with the controller. The HHTA-XXX adapter converts the 4-pin
Moles to a 4 pin phone jack connection.
