RT300 Digital Electronic Thermostat


The RT300 is a stylish and accurate thermostat with a large easy to read LCD display. The LCD display will show the current room temperature in stand-by mode, yet with a one-touch operation that makes the RT300 simple to operate. A back light and frost function adds to the features of the RT300.

The RT300 can be either surface mounted or flush switch box mounted. The standard Industry back plate provides ease of wiring. The back plate has holes to suit switch boxes and provision for surface wiring.

The RT300 must be located where it would not be subjected to extraneous heat gain/loss (such as above radiators, direct sunlight or in draughts).

Pros: Simple to install

Cons: None so far

Very nice little device - simple to install for an End User.
Didn't come with GloWorm branding, but that is good for me.

Pros: Easy to use

Cons: Only for use with batteries, would have liked to hard wire it.

Good quality and very reasonably priced compared to other sites. Neat and fit for purpose.

4/ 5

Pros: Well made, good design, easy to use, real time temperature monitoring

Cons: The prominant position of the logo!

The thermostat is well constructed, easy to use and attractive on the eye. Instruction on the use of the neutral wire (blue) would have saved some time on installation. The wire needs to be insulated and tucked away and the thermostat works fine within a control of 0.5 degree C. The monitoring of real time temperature has enabled me to balance my radiators for a better temperature distribution in the house. Very good.

5/ 5

Pros: Easy fit

Cons: Not instant response to temperature increase

I was impressed with the look of the thermostat and glad the one sent did not have the red logo as pictured on the example photo. Easy to fit and works well, although you have to get used to waiting a bit longer for the temperature increase on the thermostat to signal to the boiler, others seem a bit more instant! Apart from that slight niggle its ok.

So far so good, I havent had any issues as yet and find its really good to have the 0.5 Deg increments.
Build quality seems good and the buttons feel solid too.
Would recomend this to friends.

5/ 5

Pros: much more precise

Cons: none really

This device is much more precise than the one I used before so the temperature variation is much smaller so the overall comfort much better.
I was able to use the same backplate so installation was quick and easy

4/ 5

Nice thermostat but the badge should be removed!
Controls within half a degree as stated and the house feels better due to the closer control as compared with the old wheel type thermo.

Three existing wires from wall and only two on new thermo....just tape up the negative and connect live and switched problem.
