These are the triac controllers (like the Systemair REE range) and transformer controllers (like the Systemair ITR range). \u003cstrong\u003eEC fans\u003c\/strong\u003e have their own built-in electronics and just need a low-voltage control signal — typically 0–10V DC — to set the speed. Controllers like the Systemair MTP10 or EAC send that signal. Connecting an AC controller to an EC fan will damage the motor electronics. If you're unsure which motor type your fan has, check the product datasheet or \u003ca href=\"tel:01613993825\"\u003ecall us on 0161 399 3825\u003c\/a\u003e — we'll confirm which controller you need.\u003c\/p\u003e\n\u003ch3\u003eWhat's the difference between a triac and a transformer speed controller?\u003c\/h3\u003e\n\u003cp\u003eBoth control AC fan motors, but they work differently. A \u003cstrong\u003etriac controller\u003c\/strong\u003e (like the Systemair REE) chops the mains waveform to reduce the effective voltage — it's compact, cheap, and works well on small single-phase fans up to about 1.5A. But triac controllers can cause motor hum on some fans. A \u003cstrong\u003etransformer controller\u003c\/strong\u003e (like the Systemair ITR) reduces voltage using a multi-tapped autotransformer — it's heavier and more expensive but gives cleaner power and smoother speed control with no motor hum. For fans above 2–3A, or where noise matters (offices, bedrooms, meeting rooms), a transformer controller is usually the better choice.\u003c\/p\u003e\n\u003ch3\u003eWhat amp rating do I need for my speed controller?\u003c\/h3\u003e\n\u003cp\u003eThe controller's amp rating must be equal to or greater than the fan's full load current (FLC). Check the nameplate on your fan or the product datasheet for the FLC in amps — it's listed as the maximum current draw at full speed. A fan drawing 2.1A needs at least a 3A controller. Never undersize the controller — it will overheat and fail. If you're running two fans from one controller, add both FLCs together and choose a controller rated above the combined total. For future-proofing, it's good practice to go one size up from the minimum.\u003c\/p\u003e\n\u003ch3\u003eCan I control multiple fans from one speed controller?\u003c\/h3\u003e\n\u003cp\u003eYes, as long as the total combined current draw of all fans doesn't exceed the controller's amp rating, and all fans are the same motor type (all AC or all EC). For AC fans, connect them in parallel to the controller output. For EC fans, connect the 0–10V signal in parallel — each fan's electronics draws negligible current from the signal wire. This is common in commercial kitchens (supply and extract running together) and warehouse ventilation (multiple plate axials on one controller). If the fans need to run at different speeds, they each need their own controller.\u003c\/p\u003e\n\u003ch3\u003eWhen should I use a thermostat or sensor with my fan controller?\u003c\/h3\u003e\n\u003cp\u003eWhen you want the fan speed to respond automatically to conditions rather than being manually set. A \u003cstrong\u003eroom thermostat\u003c\/strong\u003e (like the Systemair RT 0–30) switches the fan on or adjusts speed when the room temperature exceeds a set point — common in server rooms, kitchens, and warehouses. A \u003cstrong\u003educt-mounted PT1000 sensor\u003c\/strong\u003e measures the air temperature inside the duct and feeds that reading to a compatible controller for automatic modulation. Use thermostats for simple on\/off or two-speed control; use duct sensors with BMS-compatible controllers where you need proportional speed control based on real-time conditions.\u003c\/p\u003e\n\u003ch3\u003eWhich controller do I need for an MVHR or MEV unit?\u003c\/h3\u003e\n\u003cp\u003eMost MVHR and MEV units have their own built-in speed control — you don't normally add an external speed controller. What you might need is a \u003cstrong\u003ewired remote controller\u003c\/strong\u003e (like the Vent-Axia 443283) that lets you adjust boost speed, view filter status, or switch between ventilation modes from a wall-mounted panel. Some units also accept a \u003cstrong\u003etrickle\/boost switch\u003c\/strong\u003e (like the Vent-Axia 455213) wired to the bathroom or kitchen, which triggers boost mode when switched on — typically connected to the light circuit or a separate pull-cord switch. Check your MVHR unit's installation manual for compatible controllers before ordering.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c!-- BreadcrumbList Schema --\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c!-- Organization Schema --\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c!-- Speakable Schema --\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c!-- FAQ Schema --\u003e\n\u003cp\u003e \u003c\/p\u003e","products":[{"product_id":"systemair-mtp10-10k-speed-controller-for-ec-fans","title":"Systemair MTP10 10K Speed Controller for EC Fans","description":"\u003cp\u003ePotentiometer 10kΩ for speed controlling. For the manual control of speed and air flow of electrical fans with 0-10V output EC fans).
