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.  

Figure 1  

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  

Figure 2  

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.

Summary of Contents

• Page 1: Flexible copper duct average temperature thermostat incorporates precision thermistor temperature sensors and provides a Form C relay output with an adjustable setpoint. Read these instructions carefully before installing and commissioning the temperature sensor. Do not use in an explosive or hazardous environment, with combustible or flammable gases, or as a safety or emergency stop device. The sensor installs directly into any air duct with several lengths available for a wide range of duct widths/diameters. 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 in either direction from elbows, dampers, filters, or other duct restrictions. Secure the enclosure to the duct with self-tapping screws and ensure that there is no movement of the enclosure. 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. Make wiring connections as per the wiring illustrations provided.
• Page 2: Wiring Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent electrical shock or equipment damage. Use 14-22 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. The temperature thermostat comes with the temperature sensor pre-wired to the PCB. Pull at least six inches of control wire into the enclosure, then complete the wiring connection according to the wire diagram for the applicable power supply. Connect the DC positive or the AC voltage hot side to the PWR terminal. The relay has both Normally Open (NO) and Normally Closed (NC) contacts available. The setpoint differential has 3 jumper selectable settings (Low/Mid/High). To set the switching setpoint, turn the setpoint potentiometer to the desired temperature setting. Relay Contacts: SPDT, Form C contacts (N.O. and N.C.) 5 Amps @ 30 Vac/250 Vac resistive. Operating Conditions: -10 to 50°C (14 to 122°F), 5 to 95% RH, non-condensing.
