Customer Reviews

Papa Joes Farm from Boston

The BN-LINK device performed flawlessly. I just set the desired temperature, and when the outside temperature dropped two degrees below the setting, the thermostat turned on the lamp. The lamp turned off when the temperature reached the required level. So I set the thermostat to 102 on the first day even though I intended it to be 100. My chickens were happy and healthy, and everything went wonderfully. For the first time in years, none of them developed pasty butt; they all chattered and moved around joyfully instead of huddling beneath the light and moaning about the cold. When the temperature dropped below 40 throughout the night, I turned on the extra light, and everything was OK. The second image shows the warm, content chicks.

Nicholas Hull from Austin

I use this thermostat to run a 400w heater at low temps in a cabin that is occasionally not used in the winter to keep my clothes washer from freezing. This particular model appealed to me since it includes a remote sensor that I installed at the back of the washer, which is where it will probably get the coldest. I take care not to overload the device because I am aware that it has a current limit. The outdoor temperature of 10 degrees was not enough to cause my washer to freeze or require winterization.

Peter W from Portland

I plugged it in, set the temperature, and started rocking. On chilly evenings, the chickens have a heat lamp (& days)
I had trouble with the controls at first, but it was because I hadn’t read the instructions. Even though it is obviously not advised, I left it “in the rain.” It never blinks and is still functioning just fine. However, you should definitely keep yours dry.

R. Bunge from Columbus

I have a number of brand-name products that resemble this one. Although one of them died after seven years of immaculate functioning, I’m still quite delighted with them. I believed the relay inside the device had failed. An alternative costs roughly $40. These were also on the search list, although they were listed for less. The interface and operation are identical, in fact. I think the Chinese manufacturer of the branded products has changed the packaging and is now undercutting the brand name. In any case, the unit has been operating properly for a few weeks.


How does a BN-LINK T7-H thermostat controller work?

A device used to regulate temperature is called a temperature controller. To do this, it first measures the temperature (a process variable), compares it to the target value, and then takes action (set value). The error is the difference between these two values (Deviation).

How does a BN-LINK T7-H thermostat work step by step?

The sensor of a mechanical thermostat is made of a bimetallic strip, which is two metal strips laminated together. The two different types of metal expand and contract as the inside temperature changes, turning on and off the electrical circuit that is connected to your heating system.

How do you set a BN-LINK T7-H heat link thermostat?

To enter the temperature offset Heat/Cool, long press. Value reduction or increase (e.g. Setpoint Temperature). To quickly alter a value, press and hold. To turn on the backlight and awaken the thermostat, press any key.

What are the 4 types of thermostats?

Modern thermostats come in four different basic categories: non-programmable, programmable, Wi-Fi, and smart. The cost of the thermostats is increased as you move down the list that is below. But with every thermostat, energy efficiency rises.

What should my BN-LINK T7-H thermostat settings be?

While you’re awake at home, Energy.gov advises keeping the thermostat at 68 degrees, but lowering it while you’re sleeping or gone. Your annual heating costs can be cut by as much as 10% by lowering the thermostat by 7 to 10 degrees for eight hours each day.

How do I turn off my BN-LINK T7-H Heat Link thermostat?

how to stop using the manual heater. You can always push the Heat Link’s button once (or twice for a Nest Thermostat E) to stop manual heating if it is not linked to your thermostat.

What is the most common BN-LINK T7-H thermostat temperature?

The most popular average indoor temperature is between 70 and 75 degrees. In the summer, half of the respondents had their thermostats set between 70 and 75 degrees. Most people (almost 20%) have their thermostats set between 66 and 70 degrees.

What is the most efficient BN-LINK T7-H thermostat schedule?

Every day, turn off the heat or air conditioning 20 to 30 minutes before leaving the house. Twenty to thirty minutes prior to arriving home each day, turn on the heat or air conditioning. Each night, turn down the heating or cooling an hour before bedtime. Each morning, turn up the heating or cooling around 30 minutes before you get up.

How does a BN-LINK T7-H thermostat know when to turn it on?

Typically, a bi-metal coil or a metal strip is found inside an electromechanical thermostat. This coil or strip will move in response to a change in temperature, tipping a mercury vial to one side. Mercury flowing to one end of the vial indicates that the heating or cooling system has to be activated.

Is it cheaper to leave your BN-LINK T7-H thermostat at one temperature?

In order to maintain the desired temperature in your home, your HVAC system must typically operate nonstop. Accordingly, your furnace or air conditioner might operate when you’re asleep, at work, or away from home. More energy is wasted doing this than you might save by leaving it running all the time.
