A: Very simple and good control

**Q: Hi. Is the high and low temperature difference adjustable?**
A: There is no high and low difference. You set stat to what you want, ie 20 degrees, if temperature is lower, boiler come on; raises temperature to 20 degrees; thermostat switches off (temperature reached); boiler switches off. 
If you set to 14 degrees and temperature is consistently above that..... boiler will not come on.

### ⭐⭐⭐⭐ Ideal if you want something modern without too many confusing features
*by J***N on 15 April 2022*

I chose this device to replace a failed vintage analogue unit. Its simple to operate, does not have confusing or unnecessary features or timers to set. As others have pointed out, its a bit smaller than the previous device and a small amount of patching plaster was needed. Its a two wire install, a simple 'dry contact' switch - if you have an older 3 wire install it can still be used. There's little programming to be done, no clocks, timers etc. Just set the temperature you want. There are two presets that you can use and modify, to quickly set a day and night temperature at the push of a button. Tale a moment to read the instructions and set the DIP switches inside. I'd suggest a 20 minute cycle, and conventional - I found the factory set 'proportional adaptive' setting an issue, it kept turning on and off too frequently, since the boiler has some of its own flow and temperature adaptions, and they seemed to be in constant argument. This may be the issue others have hinted on saying its 'clicking on and off a lot'. Further, the pump cycle option is pretty pointless if you also have a central heating timer elsewhere as most have - it cant exercise the pump if the timer is off, and most of us turn this to off during the summer months. Overall its a tidy and simple unit and does the job without fuss. The hysteresis - the amount it overshoots and undershoots the preset temperature to stop it hunting seems to be about 0.5 degrees and not adjustable - (some you can change) but unless your house is terribly insulated or your windows are open this wont be an issue.
