Flexible Copper Duct Average

Low Limit Thermostat

TLDC Series - Installation Instructions

INTRODUCTION

The ﬂexible copper duct average temperature thermostat incorporates

numerous precision thermistor temperature sensors and provides a

Form C relay output (NO/NC) with an adjustable setpoint. The sensor is

encapsulated in a 7.94 mm (0.3125”) OD, soft copper tube and is available

in various lengths. All probes provide excellent heat transfer, fast response

and resist moisture penetration.

BEFORE INSTALLATION

Read these instructions carefully before installing and commissioning

the temperature sensor. Failure to follow these instructions may result in

product damage. Do not use in an explosive or hazardous environment,

with combustible or ﬂammable gases, as a safety or emergency stop

device or in any other application where failure of the product could

result in personal injury. Do not exceed the device ratings.

MOUNTING

The sensor installs directly into any air duct with several lengths available for a wide range of duct widths/diameters. Select a suitable installation

area in the middle of the duct wall. To achieve the best reading, do not place in an area where air stratiﬁcation may be present. Mount the sensor

at least 1.5 m (5 ‘) in either direction from elbows, dampers, ﬁlters or other duct restrictions. Avoid areas where the sensor is exposed to vibrations

or rapid temperature changes.

Once a suitable spot is selected, drill a 9.5 - 12 mm (3/8”- 1/2“) hole. Uncoil the copper probe and slide into the drilled hole until the enclosure is ﬂush

against the duct. The airﬂow direction is not important. Secure the enclosure to the duct with #10 x 25 mm (1”) self tapping screws (not provided).

Tighten screws until the enclosure is tight against the duct and ensure that there is no movement of the enclosure as shown in Figure 1.

A foam gasket is provided on the back of the enclosure that provides a tight seal against

any air leaks.

The probe can easily be shaped to ﬁt any duct size, but observe a minimum bend radius of

4” to prevent damage to the wire or sensors. Criss-cross the duct multiple times so that the

probe covers a large section of the duct. The probe needs to be fastened onto hangers using

tube clamps or wire ties. See Figure 2.

The enclosure has a hinged cover with a latch. Open the cover by pulling slightly on the

latch on the right side of the enclosure, at the same time pulling on the cover, as illustrated

in Figure 3.

A 1/2" NPT threaded connection hole is provided in the bottom of the enclosure. Screw the

Hanger Straps

EMT connector or cable gland connector in until tight. See Figure 4. It is recommended that

weatherproof conduit or cable gland ﬁttings be used. A 1/2" NPT to M16 thread adapter and

cable gland ﬁtting is availble.

Make wiring connections as per the“Wiring”illustrations on Page 2.

Swing door closed until securely latched. For added security, 2 screws are provided that may

be installed in the integrated screw tabs. See Figure 5.
