How to Install a Thermostat on an Evaporative Swamp Cooler

A manual switch is used to turn on and off almost all Swamp Coolers. However, a thermostat can also operate a unit. Thermostat controllers come in a variety of shapes and sizes.

The DIAL 7617 is one of the most popular thermostats, but many others to choose from. It can turn on and off a swamp cooler as well as other options like just the fan. If you have any prior electrical experience, wiring a new thermostat to a swamp cooler. If you have no previous wiring experience, hiring a professional or a skilled acquaintance is advisable.

The fan motor and water pump will have to be hooked into all swamp coolers. Many coolers will additionally include a fan motor with two speeds: high and low. That means the engine will have one high Wire, one low Wire, and a hot wire. Before working on an evaporative cooler, make sure you turn off the electricity at the breaker.

The following are the steps followed to install a thermostat on an Evaporative Swamp Cooler. Follow them carefully for better results.

  1. Turn off the unit’s power and look for the current controller.
  2. Take photos, write down, and keep track of what each Wire does.
  3. Prepare the new thermostat cables.
  4. Find the location of the switch, which is usually the old manual switch.
  5. To install the new thermostat, follow the wiring diagram.
  6. Connect the new controller to the power supply.
  7. Restart the computer and test the new controller.

Wiring a thermostat to an Evaporative Swamp Cooler

When installing a new swamp cooler controller, you must identify all of the wires and what they control. Each cable will prevent the water pump and fan motor if you’re replacing an old controller; note and photograph the previous connection for future reference. Alternatively, you can track each Wire’s function to the cooler’s interior.

Common Swamp Cooler Wiring Color CodesCommon Swamp Cooler Wiring Color Codes

Red denotes a low level, whereas orange denotes a pump.

Hot Wire = Black

Standard Wire = White (Neutral)

Ground Wire = Green

While there are some specific wiring color codes, double-check them because they may be outdated or incorrect. While orange is typically associated with a water pump, many manual switches use yellow. The best approach to figuring out which wires go where is to write down and photograph the old controller with all the cables connected.

It’s also possible to follow the wires back inside the swamp cooler to discover which ones go where. Opening a Cooler and looking at the water pump, for example, will reveal which Cooler wires are in use. How a cooler thermostat can make your home

Advantages of installing a swamp cooler thermostatAdvantages of installing a swamp cooler thermostat

There are several advantages that you gain when you install a swamp Cooler thermostat at your home. These advantages include;

1. A higher level of comfort

Having a thermostat for your swamp cooler takes the guessing out of the temperature. You don’t have to wait until you’re uncomfortable to adjust the temperature. It keeps you at the temperature you prefer.

2. A timed delay

You must first turn on the pump and allow it to soak the swamp Cooler pads before turning on the fan using a typical controller. If you skip this step, hot air will blow into the house during the first few minutes after turning the Cooler on. That is taken care of by your thermostat. It uses a timed delay, which lasts between two and five minutes, during which it soaks the pads before turning on the fan. There’s no need to be concerned about it any longer.

3. Set the timer

A timer is included with most swamp Cooler thermostats. That allows you to program the Cooler to run for two, four, or six hours before shutting it down. You can, for example, arrange it to turn off a few hours after you go to bed if you don’t want it running all night. Because you’re cold, you won’t have to get up to turn it off.

4. Manual adjustments are available

If you choose, you may still operate the swamp cooler manually. This function is not taken away by the thermostat.

What are the limitations of a swamp cooler thermostat?What are the limitations of a swamp cooler thermostat

A swamp cooler thermostat has numerous advantages but a few things to consider before installing one. Therefore, you must be ready to face these challenges before you purchase and install one. Below is the list of the limitations.

1. It doesn’t feel like refrigerated air in your swamp cooler

Air that has been refrigerated feels substantially different than air that a swamp cooler has cooled. Even though your swamp cooler has a thermostat, ambient humidity still determines the amount of comfort. The thermostat controls only the temperature.

2. It is powered by high-voltage electricity

The thermostat operates at the same voltage as curling irons and phone chargers. Low voltage is used by only a few swamp cooler brands, including MasterCool® and ArrowCool®. That is something you should discuss with your cooling professional.

What about the flow of air?What about the flow of air

The outside air is drawn into the home and chilled by the swamp cooler in a standard swamp cooler system. The cooled air is then dispersed throughout the room via the vent system. When air enters the house, it accumulates. Positive air pressure is the term for this situation. If you’ve ever used a swamp cooler, you’ll know that the best way to relieve the pressure is to open the windows and doors. The air then flows back outdoors. When the chiller shuts off, this creates negative air pressure, and the windows need to be closed to protect the hot outside air from entering the house.

That is significant because, with a thermostat, you are no longer in charge of turning it on and off. The former system required you to open the windows when the chiller was switched on and close them when it was turned off. But, now that it turns on and off by itself, how does it work? Thankfully, you don’t have to turn on the heat and close the windows every time the thermostat turns off the air conditioner. Barometric dampers and up ducts are a brilliant and straightforward solution to the air pressure problem. That is how it works:

A barometric damper is a specific event that you can fit in the ceiling of a single room or numerous rooms throughout the house. The number of filters you’ll need and where you’ll position them will be determined by air movement in your home. Your HVAC professional can assist you in deciding how many you require and where they should be installed.

The damper features flaps that open into the attic and are hinged. The house fills with cooled outside air when the thermostat turns on the cooler. Positive air pressure presses against the hinged flaps as the home fills with this air. The flaps open, allowing air into the attic to escape through the gable vents and return outside.

When the swamp cooler shuts down, negative air pressure is created in the house, and the damper flaps close. One of the advantages is that you can leave your home with the air conditioner running and the windows closed. It also decreases the attic temperature, which means your swamp cooler won’t have to work as hard, saving you money on your utility bills!

Frequently asked questions:

  • What is the purpose of installing a swamp cooler thermostat, and how does it operate?

You must manually switch the cooler on and off, adjust the pump to soak the pads, and alter the fan speed with a standard swamp cooler controller. It would be best if you kept an eye on the temperature with this configuration. If it gets too hot, for example, you must turn on the pump, wait for it to wet the pads, and then turn on the fan. You must turn it down or off if it becomes too cold.

You can set the temperature where you want it with a digital thermostat. The swamp cooler will then operate on its own until it reaches the required temperature. You must pick whether you want the fan high or low, but it will automatically run until the temperature is reached.

Conclusion

If you have a swamp cooler in your home, you know how difficult it is to maintain a comfortable temperature. You must monitor the temperature, the fan speed, and the opening and closing of windows. You are, in essence, the thermostat. That does not need to be the case! Installing a digital swamp cooler thermostat allows you to adjust the temperature in your home.

A thermostat for a swamp cooler may make things so much easier! You can set the temperature where you want it instead of going back and forth by turning it on and off. This summer, stay calm and comfy!
