Rated 3 out of 5 by from Fair to middling I'm at a slight disadvantage as this was installed after we moved, so new property, new central heating system both with unknown characteristics so no base to compare it to. Having said that, the 6 temperatures a day over 7 days is great and it's pretty simple to program, it's the actual operation of the unit I find slightly bizarre. I have managed to program a pretty steady comfortable temperature throughout our bungalow however the way it warms up the place is odd. When the room temperature drops low enough to trigger the thermostat to activate the boiler, it only switches it on for a couple of minutes before switching it of again. This doesn't give time for the first radiator on the run to get even aired let alone warm. OK, you might say the thermostat doesn't know how warm the radiators are. However, if it's such an intelligent piece of kit surely it should know the last time it switch the heating on, and if a decent chunk of time has passes and it's target temperature is significantly higher than the current temperature then surely it can be programmed to run the boiler for a good 10mins so all the radiators can at least get warm before it starts running it's algorithms? It simply delays the heating process and I can only seem to get half a degree temperature increase an hour. I also find its temperature keeping inconsistent. We have it set at 20deg on an evening, however many a time I've walked passed the unit to see it reading 20.5deg with the boiler on. Other nights it's managed to drop to 19.5deg before switching on the boiler. Tonight the heating's been set at 20deg for 5 hours but it's not achieved warmer than 19.5deg. I've had to up the target temperature to 20.5deg to warm the place up! And it's warmer tonight than it has been the last couple of nights so I don't see how this could be down to the 'learning' process. Also, as with others reviews, there was no warning the battery was failing. I just woke up yesterday to a cold house (other reviewers had the heating get stuck on). All in all I wouldn't say its a bad thermostat but neither would I say it's good. I've managed to program a pretty steady heating sequence but its occasional quirks let it down.

Rated 2 out of 5 by from Not built to last Had one of these as a programmable thermostat suited my "days in", "days out". Worked OK for a while then the relay packed up - so display looked fine, but no output. Replaced with the same and that packed up as well. In my experience, these attractive little gizmos do not have a great life expectancy. If you can live with the bog-standard room thermostat, then don't change. Others have commented about the loud click, but because it's battery powered, it needs a special relay (latching), and they are noisy - can't have it both ways

Rated 4 out of 5 by from Great service Good price and delivered next day which meant we had central heating for the weekend. Installed in a few minutes and working great- just hope this one lasts longer than the original - (5 years)

The Digistat +3 Room thermostat is a battery powered unit. The batteries power the display screen and also the switching relay.
The Switch/contact rating: 16(2)A 230VAC. This means that the switch can carry up to 16 Amps on a resistive circuit and 2 Amps on an inductive circuit. The switch is termed volt free as their is no voltage on the switch until this is applied by the installer. The switch can carry a 230Vac supply.

The Digistat+3 (75750) can be used a s a replacement for the RF3 but would need some wiring changes. The Digistat +3RF (RF701SX) would be a direct replacement as all this would require would be to remove the existing SCR from its backplate, replace with the new SCR onto the existing backplate and then commission the two units together. There is no wiring necesary with this change.
