SMSCom 7-Amp Twin - Fan Speed Temp Controller

SMSCom 7-Amp Twin - Fan Speed Temp Controller

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.

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.
