Plant Nursery Temperature RegulationEffective Plant Nursery Temperature Regulation is crucial for the health and productivity of plant nurseries. Nurseries, where young plants are propagated and grown until they reach a saleable size, must maintain stable environmental conditions to prevent damage from temperature extremes. Whether these nurseries cater to retail customers, supply other businesses, or manage the specific needs of private estates, ensuring a consistent climate helps protect their delicate botanical charges.

Tailored Features of K-Kontrol Thermostats

K-Kontrol thermostats utilize a line voltage system with a liquid-filled sensing element and capillary, ideal for the dynamic environment of a plant nursery. These thermostats come equipped with either an exposed or concealed set point dial, which allows for precise adjustments. The adjustable differential ensures that the heating or cooling kicks in only when necessary, preventing drastic temperature fluctuations that can harm plants.

Offering versatility, K-Kontrol provides both single and two-stage models. The two-stage thermostats feature two single pole, double throw switches, enhancing the control over your nursery’s environment by addressing different needs for heating and cooling simultaneously. This is particularly beneficial in regions experiencing varied weather conditions, allowing for seamless transition between heating and cooling.

How K-Kontrol Manages Electric Heaters in Nurseries

The K-Kontrol thermostat is exceptionally adept at managing electric heaters, which are commonly used in plant nurseries for maintaining warmth. The thermostat is wired directly into the electric heater’s power supply. Here’s how it works:

  • Temperature Detection: The liquid-filled sensing element in the thermostat monitors the ambient temperature of the nursery.
  • Heating Activation: When the temperature drops below the thermostat’s set point, it completes the circuit to start the electric heater. This raises the ambient temperature to the desired level.
  • Automatic Shutoff: Once the temperature reaches the set point, the thermostat interrupts the circuit, turning off the heater. This prevents overheating and conserves energy.

This ensures that the nursery environment remains within optimal temperature ranges, providing a stable and controlled climate that promotes healthy plant growth.

Durability and Reliability in All Conditions

K-Kontrol thermostats are designed to withstand harsh conditions, making them a robust choice for outdoor nurseries. The units are encased in a clear, weatherproof cover that protects against the elements without obstructing visibility of the controls. Made from polycarbonate thermoplastic, the construction is both weatherproof and corrosion-proof, ensuring long-term durability. Additionally, unlike digital thermostats, K-Kontrol devices are not affected by power surges, lightning strikes, or power outages, making them more reliable in unstable weather conditions.

Installing a K-Kontrol Thermostat is Straightforward

  1. Choose the Right Location: Install on an interior wall away from direct influences like sunlight and drafts, around 5 feet above the floor.
  2. Wire the Thermostat: Ensure power is off at the breaker. Mount the base, connect the wires according to the manufacturer’s guidelines, and attach the thermostat to its base. Protective covers should be used to shield the controls.
  3. Test the Installation: Turn the power back on and test the thermostat by setting it to activate your systems. Adjust the differential settings to ensure efficient operation.
  4. Simplify with Piggyback Plug: For models with a 230V piggyback plug, simply plug the thermostat into an outlet, and then plug your heating or cooling device into the thermostat for easy setup.
