Controllers

Before purchasing a controller, there are a few questions you should ask yourself. First, what are the ratings of the items you are trying to control? For example, do you know the voltage, amperage or horsepower of your fan or heater? It is also important to be sure of how many items you want to control. Last, how are you trying to control these items? Do you want to control them with a timer, thermostat or something different? Once you have these questions answered, it will be much easier to decide which controller is right for your needs.

Solid State Variable Speed Controller - Growers SupplySpeed Controllers: Speed controllers are meant to adjust the speed of a variable speed capable motor. You can attach one to your fan motor, for example, to control the speed of the motor when you want it to run at less than 100%. At Growers Supply, we offer a variety of variable speed controllers for your needs. Depending on how many volts you need your controller to run on, the amp rating of your fan and how many fans you want to control on one unit, the right controller for you may differ. We recommend working with a knowledgeable National Account Manager or contacting us via Live Help to find the ideal unit for your specific application.

Environmental Controllers: Environmental controllers can help regulate many aspects of your greenhouse or barn environment. From humidity to lighting to ventilation, you will be in total control of the climate your plants' or animals' experience. Our Total Humidity Controller is specifically designed for the control of plant growth in greenhouses and other growing environments. It is designed to attach to humidifying and dehumidifying equipment including exhaust fans and foggers. This unit is 120/115 volt with a 15 amp maximum switching capacity. Our Ventilation and Humidity Controller is an integrated cooling thermostat and dehumidistat that can turn exhaust or intake fans on and off to remove excess heat and humidity. This unit also runs on 120/115 volts with a 15 amp maximum switching capacity.

Phason controllers are the most advanced controllers for the progressive farmer or greenhouse grower. Growers Supply proudly carries a large line of Phason controllers for different applications. It is important to note that all Phason controllers need to be hardwired and come in 115/230 volts. They are also CSA certified, water and corrosion resistant and come with a two year warranty. Phason Controllers are available for a variety of applications including temperature, speed and electronic curtain control. For more information on individual Phason controllers, visit our Thermostats and Controllers page.

Thermostats

Thermostats take action based on a temperature reading. For example, if the temperature in your barn, greenhouse or warehouse rises above a certain point, the thermostat will trigger fans to cool it down. Thermostats are perfect for controlling fans and heaters, but can also be attached to power exhaust shutters.

Thermostats should be kept protected, especially in corrosive environments, to extend their useful life as much as possible. We recommend housing your thermostats and other controllers in NEMA 4 enclosures which have a watertight seal and are corrosion resistant. When installing thermostats, most will have to be hardwired.

Thermostats come with a differential of a few degrees. The differential is how many degrees the temperature has to change before your fan or heater turn on and off. This prevents the thermostat from telling your equipment to turn on and off every time there is a slight temperature change. Without this differential, your equipment would constantly turn on and off, increasing your electricity bill and wearing out the motor.

Commercial Thermostats: Whether you need to control the temperature of a small hobby greenhouse or a large agricultural building, we have a DuroStat Thermostat that will fit your needs. Our line includes single and double NEMA 4 thermostats, watertight thermostats and more.

For livestock housing applications, our DuroStat NEMA 4X Curtain Controller Thermostat is perfect for controlling temperature in corrosive environments. This unit is designed to be used to control curtain/inlet actuators as temperature changes. The DuroStat Electronic Thermostat has a clear digital display, the easiest setting and the widest temperature range. More accurate than coil-style thermostats, this unit gives you precise control of fans, heaters and other devices.

Timers

Before you decide on a timer, make sure you have all the information you need to make an informed choice. First, you need to determine the cycle length for your timer. This is the minimum length of time during which the operations occur without repetition. This can be a minute, hour or day. Next, you need to determine the number of operations required. One on/off cycle consists of two operations. You also need to decide on the minimum duration of the shortest on and off operations.

Do you know the load and voltage requirements of the equipment you want to control? In order to choose the right timer, you need to know the horsepower and voltage of a motor or amperage and voltage of the object. Next, you have to determine the switch type, or number of items being controlled. The options are single pole single throw (SPST), double pole single throw (DPST), double pole double throw (DPDT) or a less standard option.

The NEMA rating of the timer you are interested in is also important. The NEMA rating for electronic enclosures that are available for timers are Type 1 metal box for indoor use where no oil, dust or water is present or the Type 3R non-metallic box for outdoor use and protection against rain, sleet and snow. Last, determine if you are looking for a mechanical or electronic timer. If timing accuracy is required, then choose an electronic timer. These require initial programming and battery upkeep. The mechanical models are simpler, but may require additional tripper pins for their applications.

At Growers Supply, we offer analog and electric timers, as well as watertight units.

24-Hour Timers: Our 24-hour Intermatic Timers are ideal for industrial, commercial and residential applications. All Intermatic units are 24-hour timers and include one set of tripper pins. Depending on your needs, we offer an electronic switch timer and watertight timers, besides the basic 24-hour timers. For help choosing the timer for your application, feel free to contact us.
