SMSCom Mk2 Fan Speed Controller - Keep Your Grow Room At The Right Temperature!

The Mk2 SMSCom Twin Fan Speed Temperature Controller is a slender and compact version of the ever-popular original SMSCom Twin Fan speed controller. Not only that, it's also cheaper and comes with an IEC power cable and socket, making it easier to switch to longer cables if required. The most popular model in the range just got even better!

• SMSCom – Great quality and value-for-money
• The MK2 (latest) version of the 7 amp model in the range
• Gives great control over your garden air temperature
• Controls the speed of both an intake fan and an outlet fan
• Maintains a user-set temperature in your grow-room via an external temperature sensor on a fitted 2.9 metre lead
• Allows the user to set a minimum fan speed to ensure adequate air exchange even at low temps
• Maximum fan speed setting – great for using oversized fans
• Supplies 2 outputs up to 800 Watts (3.5 Amps) each

Please note: though digital fan speed controllers (like this one) are a very cost-effective solution, they may generate a slight humming sound in the fan. This is an unavoidable consequence of using pulse width modulation to regulate fan output. If this might be a problem for you then we highly recommend the SMSCom Hybrid range of Fan Speed Controllers, which instead use heavyweight transformers and control fans without introducing a hum.

Fan Controllers - Why Are There Different Types?

This fan speed controller is not designed for use with Isomax fans. If that’s your intention, then please take a look at the SMSCom Hybrid Controller.

 Contains:

1 x Smscom 7-Amp Twin Fan Speed Temperature Controller MK2

How the SMSCom 7A Twin Mk2 Fan Speed Controller Works:

This is the 7A MK2 version of the SMSCom Twin Fan Speed Controller - the most popular of all the model types in the SMSCom range. It has all of the features that made the original such a storming success, regulating intake and extractor fans according to room temperatures. This version, however, is much more compact taking up only 50% of the space of the original!

This unit has two sockets on the front (one for your intake and one for your extraction) and 3 controller knobs. The first control allows the user to set a minimum fan speed. This allows the user to set the lowest fan speed required for adequate air exchange in the garden space.

The second control on the SMSCom Mk2 Twin Fan Speed Temperature Controller allows the user to set the desired temperature to be maintained. The SMSCom fan speed controller has a temperature sensor on a 2.9 metre long lead which is ready-fitted to the unit. The SMSCom fan speed controller will control the speed of both the input and outlet fans (within the bounds of the min and max fan speed that you set) to maintain the temperature that you set with the temperature control. For this to work, the sensor must be placed in an appropriate position in your grow-space, such as at plant-top height.

The third controller knob allows you to set the maximum fan speed. This is particularly useful when using oversized duct fans. If your fan is larger than required for the size of the grow area, you may not want it to kick in at full speed – using the maximum fan speed knob will ensure that this doesn’t happen.

How to use the SMSCom 7-Amp Twin Mk2 Fan Speed Controller:

Plug your inlet fan into the left-hand socket marked "FAN AIR IN". Plug your outlet fan into the right-hand socket marked "FAN AIR OUT".

Locate the temperature sensor in an appropriate place in the grow-room. A good place is usually in the centre of the room at roughly the same height as the tops of your plants, but away from direct light.

Set the desired minimum fan speed, room temperature and maximum fan speed using the dials on the front of the Smscom Twin Fan Speed Temperature Controller. The unit can now be plugged in to switch it on.

Remember that the minimum fan speed that you set on the front of the SMSCom Twin Fan Speed Temperature Controller always needs to be high enough to remove adequate amounts of stale air from your grow space, even when the room is cold. If the fan speed is too low, there may not be enough fresh air exchange to replenish CO2 for optimal plant growth. Also, having your fan speed too low may not keep the humidity down enough for good plant growth and to reduce the chances of mould or rot during flowering.

The Smscom twin fan speed temperature controller can adjust the speed of fans with a maximum power consumption of 800 Watts (current draw of 3.5 Amps) each. However, it should never be used to control the speed of any type fan which has their own speed control. This includes most circulation-type fans. Using the Smscom twin fan speed temperature controller to control a circulation fan will invariably burn out the controller or the fan itself.

The Most Popular Hybrid Model Just Got an Upgrade!

Mk2 SMSCom Hybrid Pro Fan Speed Controllers are the simplest, quietest and most efficient way to regulate the output of in-line duct fans –just plug them into the controller, set the dials and let the on-board computer system do the rest. Hybrids completely remove buzzing and humming noises by combining heavyweight transformers with clever digital technology. This model is the most popular in the range - and it's now been upgraded at no extra cost! It features a 'maximum' setting so that you can use over-sized fans without them ever kicking in at their full output level. The Pro's light sensor can be used to increase extraction levels for 7 minutes an hour during darkness hours, lowering humidity levels and preventing issues with rot. These improvements really have turned a great product into something truly legendary!

How the Mk2 SMSCom Hybrid Pro Fan Speed Controller Works:

Your plants are happiest when they are exposed to a consistent climate. Tropical plants thrive at around 25 degrees centigrade during the light period and 15 degrees while dark. As outside temperatures fluctuate, sometimes it is necessary to vary the amount of air extracted from the grow area via your duct fan to maintain the temperature indoors.

The Mk2 SMSCom Hybrid Pro Fan Speed Controller regulates the quantity of air extracted from the grow area by increasing or decreasing the output of in-line duct fans. It requires no wiring or electrical skill to install; intake and outlet duct fans can be plugged directly into the corresponding UK standard 3-pin sockets located on the unit. The temperature probe is then placed near the canopy of your plants, using the 4.5m cable. Highly accurate data gathered from the probe is processed by the on-board computer and used in the duct fan regulation process.

The Mk2 SMSCom Hybrid Pro Fan Speed Controller utilizes a heavyweight relay to regulate the power supply, and you'll notice a small clicking sound as the unit moves between each of its 5 speeds. This high quality relay ensures that the unit maintains its reliability at all times.

Hybrid Controllers work differently to budget controllers. Cheaper 100% digitally controlled units work by pulsing electricity, effectively switching power ON and OFF constantly, but at different rates, to vary the duct fan output levels. It is this pulsing effect which creates unwanted noise. The controller in the SMSCom Hybrid properly reduces and increases the amps/watts delivered to in-line duct fans. This way, the duct fan is always ON, and power is delivered smoothly, reducing humming and buzzing sounds to zero.

The Mk2 SMSCom Hybrid Pro Fan Speed Controller model now features a 'maximum fan-speed'. For anybody using over-sized fans this is an absolute godsend. On the old model, fans would kick-in at their full output levels whenever temperatures reached your chosen setting. Now you can control their maximum level, so that you can run over-sized fans at lower outputs, without noise causing issues.

A light sensor is also included with this model. To use it, simply remove the protective cap - the Mk2 SMSCom Hybrid Pro Fan Speed Controller will then automatically detect dark periods. During these dark periods, without heat from lighting, fans generally tend to run at the minimum setting. Though this is fine for maintaining ideal temperatures, the Hybrid Pro also increases output levels by one setting for 7 minutes every hour, which ensures that humidity levels don't build up in the room. This greatly reduces the chances of experiencing botrytis (rot) or other mould related issues. If you don't wish to use this feature, you can turn it off by simply replacing the light sensor's cap.

All SMSCom products come with a 5-year manufacturer's warranty starting from the date purchased.
