Can Fan Thermostat Mod Tem 035 – Silent Step Controller for Max-Fan & Iso-Max

The Can Fan Thermostat Mod Tem 035 is a professional-grade step transformer that automatically regulates your grow room's temperature while keeping your extractor fans completely silent.

Are you tired of temperature spikes stressing your plants and that unbearable humming noise your extractor makes when you try to lower its speed?

Cheap fan controllers use triac technology that causes a loud, vibrating buzz in the motor at lower speeds. Not only does this ruin your stealth setup, but poor temperature management can also lead to stunted growth, mold, and a ruined harvest.

The Can Fan Thermostat Tem 035 solves this instantly. By using a 5-step voltage selector instead of a continuous dimmer, it adjusts your fan's speed based on the temperature without generating any motor noise, ensuring a perfect, stealthy environment.

Flawless Climate Control in One Device

This robust controller acts as the brain of your Air Extraction System. You simply set your desired temperature, and the thermostat automatically switches between its voltage steps to speed up or slow down your Max-Fan or Iso-Max extractor. It gives you absolute peace of mind, knowing your plants are breathing perfectly without drawing unwanted attention through noise, making it a top-tier choice for your Climate Control strategy.

Key Features and Benefits

• 5-Step Voltage Selector (0-100-140-170-200-230 V): Eliminates motor humming, ensuring a 100% stealthy and silent operation.
• Automatic Temperature Control: Keeps your grow tent climate stable, preventing heat stress and maximizing your yield.
• High Compatibility: Perfectly designed to work seamlessly with Max-Fan (250/355/400/500/630) and Iso-Max (250 and 315) extractors.
• Industrial Build (170 x 255 x 140 mm / 5 kg): Heavy-duty copper coils and a built-in F T-5.0 fuse guarantee extreme durability and safety against power surges.
• 3.5 A Intensity: Handles powerful industrial fans without breaking a sweat, giving you reliable performance cycle after cycle.

How to Set It Up in a Few Steps

Getting your climate dialed in is straightforward. Just follow these simple steps to get your silent ventilation running:

1. Mount the thermostat securely on a wall outside your grow tent to protect it from extreme humidity.
2. Connect your compatible Max-Fan or Iso-Max extractor to the controller following the wiring diagram.
3. Place the temperature probe inside the grow area, ideally at the canopy level of your plants.
4. Set your target temperature on the dial and let the controller manage the voltage steps automatically.

Frequently Asked Questions

Can I use this thermostat with any extractor fan?

No, this specific model is engineered and calibrated for Can Fan models, specifically the Max-Fan (250, 355, 400, 500, 630) and Iso-Max (250, 315). Using it with incompatible fans may cause damage or inefficient operation.

Why is it so heavy (5 kg)?

The weight comes from the heavy-duty copper coils inside the step transformer. Unlike cheap digital dimmers, these coils physically change the voltage, which is the only way to reduce fan speed without causing a magnetic hum in the motor.

Does it control both intake and exhaust fans?

This specific unit is designed to control a single high-capacity extractor fan up to 3.5 Amps. If you need to control multiple fans, ensure their combined amperage does not exceed the 3.5 A limit, though it is optimized for a single main exhaust.

Personal Experience of Pevgrow’s CEO (Alan)

When you upgrade to larger grow spaces, the noise from dimmed extractors becomes a real headache. I remember using standard cheap controllers and dealing with that constant, annoying buzz that made stealth impossible. The day I switched to the Can Fan Tem 035, the silence was deafening. It completely changed the game for my indoor setups.

I always pair this controller with an Iso-Max. The combination of the acoustic casing of the fan and the step-transformer technology of this thermostat means you can stand right next to the grow room and hear absolutely nothing. It is a heavy, industrial piece of gear, but it is an absolute must-have if you value discretion and precise climate control as much as I do.
