Nice neat easy to use item. Yet to install it, but looks easy enough and will fulfil the need. Straight replacement for 15 year old Drayton Bi-Metallic Thermostat.

Improved DS1-L, easier for anyone unfamiliar to operate. v2 does not fit DS1 backplate so needs a back box and making connections from underside can be awkward. DS1-L were prone to seize up preventing temp adjustment so will see if v2 better

Thermostats replacing DS1 and to date seem to work very well. The display is very useful as you can see at what temp the stat kicks in.
