Overview

The nVent THERM26F Thermostat Controller is a robust, mechanical temperature control solution designed for industrial applications. Engineered by nVent, a trusted name in electrical enclosure thermal management, this unit (SKU: THERM26F) provides reliable operation for controlling filter fans and heaters within enclosures. Its compact dimensions of 2.64x1.97x1.50 inches and light gray plastic housing (RAL7035, UL94V-0 rated) ensure easy integration into various industrial environments. This thermostat operates on a 230V supply and features a Fahrenheit temperature display, with a control range of 40°F to 140°F. The THERM26F utilizes a bimetal sensor to accurately register surrounding air temperature. Its snap-action contact mechanism allows for switching of both inductive and resistive loads, functioning as either a normally closed (NC) break contact or a normally open (NO) make contact. The switching capacity is substantial, rated up to 10A resistive / 4A inductive at AC 250V for the NC contact and 5A resistive / 2A inductive for the NO contact, with a DC rating of 30W for both. Installation is straightforward thanks to the integrated clips for vertically mounting on a standard 35 mm DIN rail (EN 60715). The unit's IP20 protection rating ensures it is safe from solid objects greater than 12.5mm, suitable for many controlled environments. For applications requiring a tighter temperature differential, an optional integrated resistor (RF) can be connected to the 'N' terminal to provide thermal feedback, thereby improving the switch temperature difference. This feature is particularly useful in environments where precise temperature control is critical. Key features and specifications of the nVent THERM26F include: * **Reliable Mechanical Control:** Bimetal sensor for accurate ambient temperature detection. * **Versatile Switching:** Snap-action contacts support both NC and NO configurations for diverse load control. * **High Switching Capacity:** Capable of handling significant resistive and inductive loads up to 10A. * **Wide Operating Range:** Controls temperatures from 40°F to 140°F. * **Easy DIN Rail Mounting:** Integrated clips for quick installation on 35mm DIN rails. * **Durable Construction:** UL94V-0 rated plastic housing in RAL7035 light gray. * **Optional Thermal Feedback:** Integrated RF resistor for improved temperature difference control. The THERM26F is an ideal choice for maintaining optimal operating temperatures in electrical enclosures, preventing overheating of sensitive components or ensuring proper functionality of heaters. Its robust design and adherence to industry standards like cURus (File No. E164102) and CE certification underscore its suitability for demanding industrial settings. Trust nVent for dependable thermal management solutions that protect your equipment and ensure operational continuity.

How to Install the THERM26F Temperature Controller

This guide provides step-by-step instructions for installing and configuring the THERM26F temperature controller in an electrical cabinet.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors

  1. Mount the controller

    Secure the THERM26F controller to the upper area of the electric cabinet using the integrated clips. Ensure it is level and firmly attached, avoiding proximity to heat-generating components.

  2. Connect the wiring

    Use heat-resistant cables if the ambient temperature exceeds 70°C (158°F). Connect the wiring to the appropriate terminals, ensuring correct polarity to avoid personal injury or equipment damage.

  3. Configure the temperature settings

    Set the temperature on the controller, allowing for the maximum hysteresis of 5K +2/-3K. Verify the settings using a multimeter to ensure proper voltage and functionality.
