Dramm Microfan Thermostat - Single Stage

Dramm Microfan Thermostat Single Stage - Precision Greenhouse Temperature Control

The Dramm Microfan Single-Stage Thermostat delivers durable, precise mechanical temperature control for greenhouses, grow rooms, warehouses, farms, and industrial environments. Built to replace rusted metal boxes with unreliable hand-marked calibrations, the Dramm thermostat features a sealed PVC housing and stainless steel coiled sensor that withstand rough, humid environments while maintaining accuracy to 1 degree Celsius. The single-stage configuration switches one circuit on or off based on temperature - ideal for controlling a single piece of equipment such as a fan, heater, or cooling unit. CSA approved for confidence in commercial and agricultural applications.

Key Features & Benefits

• Single-Stage Control: The single-stage configuration switches one circuit on or off based on temperature - ideal for controlling a single piece of equipment such as a fan, heater, or cooling unit.
• Sealed PVC Housing: Corrosion-resistant PVC enclosure protects internal components from moisture, fertilizer, and chemical exposure common in greenhouse and grow room environments.
• Stainless Steel Coiled Sensor: Durable sensor material resists corrosion and maintains accurate temperature reading over long service life in humid conditions.
• 1 Degree Celsius Accuracy: High-precision temperature sensing ensures equipment activates and deactivates at the intended set points without large deviations that waste energy or stress plants.
• SPDT Switch Contact: Single-pole double-throw switch configuration provides superior reliability and enables both normally-open and normally-closed wiring configurations for maximum installation flexibility.
• CSA Approved: Safety certification provides confidence for use in commercial, agricultural, and industrial applications requiring certified electrical components.

Who Should Use This

Ideal for greenhouse operators, commercial cultivators, and facility managers who need reliable mechanical thermostat control for heating or cooling triggering at a single temperature set point. The ruggedized design is well-suited for humid growing environments where electronic thermostats may be susceptible to moisture damage.

Compatibility

Compatible with fans, heaters, cooling units, ventilation systems, and other equipment requiring temperature-triggered control. Flexible wiring options support a wide range of installation configurations. Verify amperage and voltage ratings against your load requirements before installation.

Frequently Asked Questions

What is the difference between single-stage and two-stage thermostats?

A single-stage thermostat controls one circuit at one temperature set point - for example, turning on a fan when temperature rises above a set value. A two-stage thermostat controls two independent circuits at two different set points - for example, activating ventilation at 75F and cooling at 85F - providing more nuanced environmental management.

Is the Dramm thermostat suitable for humid greenhouse environments?

Yes - the sealed PVC housing and stainless steel coiled sensor are specifically designed to withstand the high humidity, condensation, and occasional chemical spray exposure typical of greenhouse and grow room environments.

Does this thermostat require any special wiring?

The SPDT switch configuration supports flexible wiring for both normally-open and normally-closed applications. Consult the Dramm installation guide for wiring diagrams and ensure your installation is performed by a qualified electrician if required by local code.

Can the Dramm thermostat control both heating and cooling equipment?

A single-stage thermostat controls one circuit - it can control either a heating or cooling device, but not both independently. For simultaneous heating and cooling control at different set points, use the two-stage model.
