Salus ERT20RF Thermostat Quick Review

Salus ERT20RF Thermostat Quick Review. Good dial style room thermostat with RF. Works as a great replacement for older Salus models, such as the RT500RF, and even newer models like the RT310RF (transmitter can also be used with the RXRT505). Extremely easy to use, combining old school technology using a simple analogue dial, with more advanced tech in the form of remote / radio frequency. 

Salus ERT20RF transmitter and receiver

The ERT20RF (For sale here) is very versatile, working with both volt free and AC setups. That versatility stretches further with the ability for this thermostat to be used with many different system types that use the most common heating fuels. Oil, electric and gas, all are compatible.

Problems

Just to point out, reviews are very good for this model. The overall review score is 4.3 out of 5 on Amazon. With that said, some users find it quite slow to respond due to its integrated lag. Most people reporting this issue claim the lag, or time the unit needs to be fully functional again is around 10 minutes if the receiver is turned off (power cut etc). And, from heating transitioning, being on / off etc, the delay is quite noticeable.

Like so many other thermostats, the temperature is not 100% accurate either. Last problem is the battery duration. There have been quite a few users left disappointed due to how frequently the batteries need to be changed. Other than these issues, the Salus ERT20RF is reliable and does work well. Most buyers are very happy with their ERT20RF. Furthermore, Salus gives a two-year warranty with this model.

Flashing Red Light

The flashing red LED light is either one of two things. It's either the pairing is broken, and it needs to be paired again. Or the batteries are low and need replacing. For most people with this problem it is usually the batteries that are at fault. Change them and that should fix the issue. (very easy to do).

Not Working

If the unit does not seem to be working, check all the usual culprits. Is everything switched on. When were the batteries last replaced. Is all the wiring intact. If you need more help please refer to the manual, which can be found here (includes a basic wiring diagram).
