• Versatile 3-Terminal Configuration: Features three faston tab terminals (N/O - Normally Open, C - Common, N/C - Normally Closed), offering flexibility for both heating and cooling applications, though primarily used for heating in catering.

• Standard Shaft Length: A 28mm shaft length ensures compatibility with common control panels and mounting configurations.

• Simple & Effective Control: Provides a basic, intuitive method for operators to manually adjust and maintain desired temperatures.

• Durable Construction: Built to withstand the demands of commercial kitchen environments, ensuring longevity and consistent performance.

• Optional Accessories Available: Knobs and bezels are available as optional accessories, allowing for customisation and a professional finish (sold separately).

• Associated High Limit Thermostats: We can also supply compatible high limit thermostats as associated accessories, offering an additional layer of safety (sold separately).

How a Single Pole Capillary Thermostat Works

A single pole capillary thermostat operates on the principle of thermal expansion. A liquid-filled sensing bulb, connected to the main thermostat body via a thin capillary tube, is placed in the area where temperature needs to be controlled (e.g., inside a hot cupboard or immersed in water). As the temperature of this area changes, the liquid inside the bulb expands or contracts. This change in volume creates pressure within the sealed capillary system, which is transmitted to a bellows or diaphragm inside the thermostat body.

This mechanical movement then actuates a single pole electrical switch (16A, 250Vac). When the temperature reaches the pre-set point, the switch either opens (for heating applications) or closes (for cooling applications, or as a safety cut-out). This breaks or completes the circuit to the heating element, thereby controlling the temperature. The N/O, C, and N/C terminals provide flexibility for wiring the thermostat to turn a device ON or OFF at a specific temperature.

Important Installation & Safety Notice

Installation and wiring of this thermostat must ONLY be performed by a qualified and licensed electrician or appliance technician in strict accordance with all local electrical codes, safety regulations, and the appliance manufacturer's instructions. Always ensure the main power supply to the circuit is disconnected and locked out before any work is carried out. Improper installation can lead to electrical shock, fire, equipment damage, or void its warranty. Ensure the sensing bulb and capillary are correctly positioned to accurately reflect the temperature being controlled.

Frequently Asked Questions (FAQs)

Q1: What is the purpose of the 1.5-meter capillary?

A1: The long capillary allows the sensing bulb to be placed precisely where the temperature needs to be measured (e.g., deep inside a hot cupboard or immersed in a liquid), while the main thermostat body and control shaft can be mounted conveniently on an external control panel.

Q2: Can this thermostat be used for both heating and cooling applications?

A2: While commonly used for heating, its three terminals (Normally Open, Common, Normally Closed) allow for flexibility. You can wire it to turn a device ON when the temperature rises (e.g., for cooling) or OFF when it rises (e.g., heating cut-off), depending on your wiring configuration.

Q3: Are the knob and bezel included with the thermostat?

A3: No, the knobs and bezels are optional accessories and are sold separately. This allows you to choose the style that best fits your equipment or simply replace the thermostat without needing a new knob if your existing one is still functional.

Q4: What is the benefit of a liquid-filled sensing bulb?

A4: Liquid-filled sensing bulbs offer excellent temperature responsiveness and accuracy over their operating range due to the consistent thermal expansion properties of the liquid, providing reliable temperature control.

Q5: What is a "high limit thermostat" and why might I need one?

A5: A high limit thermostat is a safety device designed to trip and shut off a heating element if the temperature exceeds a dangerously high, pre-set limit. It acts as a secondary safety measure, preventing overheating in case the primary control thermostat fails. We can supply these as associated accessories for enhanced safety.
