Honeywell Home Y3C710RFEU T3R Thermostat

The Honeywell Y3C710RFEU T3R thermostat is an energy efficient replacement for existing HVAC systems. The device has a modern design and thanks to its built in learning system, it can help you save money on your energy bill. It offers versatile settings for all seasons, and offers multiple settings for comfort and convenience.

The Y3C710RFEU consists of an electronic control unit and a wireless controller. Usually called a receiver. The programmer is housed on the wall and can be placed in any room using the included transmitter. The control unit’s main body is quite basic in design.

The digital display on the front of the controller lets you quickly see the current system settings. There are also two buttons, a plus and a minus, and three others under the plastic cover at the front to allow the user to quickly change settings. Some users have claimed to have a very hard time programming the T3R, and that the manual is not very helpful. If this is the case for you, take a look at the video below if you need a quick rundown on how to use and program the T3R.

Setting a temperature on the Y3C710RFEU is easy and quick with two digital dials or one digital display. You can also set a timer and a holiday function, which will automatically change settings at certain times of the day, such as when everyone wakes up or when the house is empty. Each device can have up to four independent zones, making this a perfect option for larger households with multiple rooms.

T3R Main features include:

• • • 7-Day [5/2] thermostat
    • Digital display with blue back light
    • Up to 4 on/off cycles each day
    • Holiday mode
    • Auto / Manual modes
    • 1 hour boost option
    • Energy saving potential
    • Very versatile in terms of compatibility with boilers

The Y3C710RFEU Thermostat uses an internal programmable micro-controller to monitor your home’s temperatures remotely and adjust your HVAC system accordingly. And while this model is not considered the same as a full blown “smart” thermostat, as it does not have remote access capability [no App etc], it does have an intelligent self-learning ability that can help save energy.

This provides you with greater comfort control over your environment without requiring you to monitor your heating system manually. There’s also a wired model available [T3C110AEU T3] should you not want or need the wireless model talked about here. Both take 2 AA batteries.

The T3 wired is known to be an easy replacement for the following models: Honeywell CM907 and DT90E. It’s also a direct replacement for many other Honeywell programmers. Updated models are the T4 and T4R.
