Customer reviews

Austin Murphy United States
It is actually silent. It employs a TRIAC, which I later discovered works like a dimmer, according to the box. This t-stat continuously increases and decreases the dimming level to closely monitor the setpoint rather than turning it on and off when the room becomes visibly hot or cool. According to how much power it allows, the display, which displays 0–5 heat wave squiggles, gives some indication of this.
Rose United States
I discovered this for my two baseboard heaters. It is programmable and maintains the temperature I set for my room. In addition, it must be saving me a tonne of money because it sends any unused electricity back to your electric box. Both the installation and the directions are fairly simple to grasp. I’ll be buying more of these for other rooms, particularly those with two heaters.
Taz United States
I hired an electrician to install it since it was defective; it took him an hour to identify the problem after exhausting all other possibilities. Reconnected the old one, and it is operating normally. Prior to this, I bought two of these devices, and they both function properly.
Robert N Horspool Canada
Our previous baseboard thermostat was easily replaced with this programmable thermostat using only a screwdriver. In hardly any time, we were moving. It was a little more difficult to program it to raise and drop the temperature at the right times, but the instructions made so clear how to do it. We are pleased with it greatly.

Can you use a Honeywell RLV4305A1000 programmable thermostat with electric baseboard heat?

There are intelligent thermostats that can be used with electric baseboard heaters, yes. But not all smart thermostats follow this rule. Therefore, it’s crucial to pick a wise upgrade that works for your house.

What type of thermostat is typically used with electric baseboard heaters?

Line or high-voltage thermostats are used to regulate electric baseboard heaters. The usual electrical load that line voltage thermostats regulate is 120V/240V.

What is the average life of a Honeywell RLV4305A1000 programmable thermostat?

Your thermostat will ultimately become obsolete, just like any other technology. Modern home thermostats typically last 10 years, but they are often updated earlier due to market advancements.

How do you use a Honeywell RLV4305A1000 electric baseboard heater thermostat?

Set the thermostat to the appropriate temperature to turn on a baseboard heater; it will run until the temperature is attained. The heater restarts if the temperature lowers later. The heater and the floor should be separated by at least 3/4 inch.

What temperature should electric baseboard heat be set at?

60 degrees when you’re asleep or away, 68 degrees when you’re at home. (With the exception of ceiling cable heat, which should only be changed by 2 to 3 degrees at a time.) You can save about 2% on heating bills for every degree you lower the temperature in your house.

How long do Honeywell RLV4305A1000 electric baseboard thermostats last?

The normal lifespan of a ‎Honeywell Home RLV4305A1000 E1 Programmable Thermostat for upkeep, repair, or replacement is variable (unlike air conditioners that need a tune-up every year). However, in general, you can count on your thermostat to endure for at least ten years. Thermostats may start acting up after ten years.

How often should you replace a Honeywell RLV4305A1000 programmable thermostat?

The average ‎Honeywell Home RLV4305A1000 E1 Programmable Thermostat lasts 10 years. However, as more recent, more effective thermostats hit the market, you could need to replace yours sooner.

How does a Honeywell RLV4305A1000 electric heater thermostat work?

A thermistor is a cheap instrument that digital thermostats utilize to measure temperature. This resistor enables temperature-related changes in electrical resistance. A digital thermostat’s microprocessor has the ability to sense resistance and translate the result into a temperature reading.

How long do batteries last in a Honeywell RLV4305A1000 programmable thermostat?

Batteries for thermostats typically last 8 to 12 months and aid in maintaining settings during power outages. Low batteries in digital thermostats are a frequent reason why your home’s heating and cooling system won’t work.

Can I replace my Honeywell RLV4305A1000 programmable thermostat myself?

A skilled do-it-yourselfer can install most programmable thermostats and certain smart thermostats. Don’t forget to shut off the HVAC equipment’s breaker!
