Low Limit Switch are most widely used in HVAC equipments, cooling coils and heat exchangers. The thermostat and capillary sensing element provide an antifreeze function by sensing the lowest temperature along any one foot section of capillary tube. Automatic reset relays signal the building management system and also cut off the fan.
What does Lo mean on the thermostat?
Lo. LO means Low temperature, and not low battery – so no worries! Low battery sign is usually "Lo batt" in a corner of a display. LO is shown in the display where the temperature is normally displayed. The temperature sensed by the thermostat is lower than the 40 F (4 C) lower limit of the thermostats display range.
What is a good temperature to set my thermostat?
Set your thermostat to 68° when you’re home. When homeowners ask us what they should set their thermostat to when they’re home, we always suggest going no higher than 68°. But for optimal savings, we suggest going 10 degrees lower (58° F) when you leave the house for the day. If you can go lower, do it.
What programmable thermostat should I buy?
It can be hard to find a thermostat that works with electric baseboard heat, and one of the best options out there is the Mysa Smart Thermostat. This programmable thermostat works with 120-240v electric baseboards and electric fan-forced heaters, and it requires one neutral or second live wire.

What is a Low Limit Switch?
The Low Limit Switch plays the role of frost protection switch in water treatment and water supply plants, HVAC air conditioning( preferred in cold areas) etc. Low Limit Switch is designed to monitor low temperature and to prevent damages that may occur due to frost accumulation.
What causes a furnace to not provide enough heat?
Dirty filters are the most common cause of furnace problems. Dust and dirt restrict airflow—and if the filter gets too clogged, the heat exchanger will overheat and shut off too quickly, and your house won't warm up. If the blower is running but no heat is coming out, replace the filter.

What is the purpose of a limit switch?
A limit switch is an electromechanical device operated by a physical force applied to it by an object. Limit switches are used to detect the presence or absence of an object. These switches were originally used to define the limit of travel of an object, and as a result, they were named Limit Switch.
What triggers a limit switch?
In most cases, a limit switch begins operating when a moving machine or a moving component of a machine makes contact with an actuator or operating lever that activates the switch. The limit switch then regulates the electrical circuit that controls the machine and its moving parts.
What is an example of a limit switch?
Limit switches can also be used as safety interlocks to prevent machine parts from moving any further when a specific point is reached. A good example of this is an automatic garage door.
What are two types of pressure switches?
There are two main types of pressure switches: mechanical pressure switches and electronic pressure switches.
When it gets hotter, raise the thermostat!
You may think we’ve been affected by heatstroke when you read that. Isn’t intense outdoor heat a time when you need the AC working the most? You do need the air conditioner working, but during heatwaves, you must be cautious about making the AC strain so much that it malfunctions.
The lower limit
Even when the temperature outside isn’t at heatwave levels, we recommend you don’t lower the AC’s setting below 68°F. This temperature is already more than cool enough for most people, and many will find it too cold.
Heat gain
Now that we’ve gotten through two major warnings, we want to talk about why raising the thermostat can help with cooling your house and saving energy. The bigger the difference between the indoor and outdoor temperatures, the faster heat from outside will enter the home. This is called heat gain.
