Rated 3 out of 5Â by John1234 Digits fail
Had this for 2 years and now half the digits have failed. Can't tell the difference between a 7 8 or 9. Reliability very poor score.

I installed one of these at home and working great. The TPI control "ramps" down the boiler time as the temperature gets close to set point. Less overshoot and a more stable house temeperature. Night setback and holiday mode are good.
I am about to fit these and the DT90E to some fan convectors at work with old 2-wire thermostats with wide overshoot / undershoot of temperatures.
Best feature of all for a School enviorment is being able to set the Max / Min adjustments within the installer mode which should prevent the unauthorised adjustment of the settings.
Scewfix should consider stocking the CM907 unit as well for anyone wanting a 7 day version.

Easy to install and programme. The unit replaces both time clock and room thermostat. The literature specifies 6 on/off periods per day which is not strictly correct.
It is always controlling. Target temperatures are user programmed for the whole day and after the target temperature is reached it is maintained very precisely.
In manual a target temperature is user programmed and in the off position a frost protection is temperature can be set.

Easy to install with a good range of features and a backlit screen, makes it easy to read in darker areas.
