Drayton Digistat 2 Replacement

What can replace the old and very basic Drayton Digistat 2. Among other models, two that are easy direct replacements would be the Honeywell CM907 and the Honeywell T4 (Both battery powered models, not mains). The other two are the Digistat +2 and Digistat +3 [pictured below]. The +3 can have up to six on / off periods per 24 hours.

The Drayton Digistat +3

Looking for the wireless version of Digistat +3, find that here: Drayton 123042 Digistat +3RF. Alternatively, you can also replace the Digistat 2 with much more up-to-date models, such as certain models of HIVE or Nest (depending on your system) and the Drayton Digistat +3. Just be sure to get the wiring / terminals right.

Replacing with a HIVE can be a little bit more complicated due to some systems, such as those using combi boilers, needing some adjustments electrically to be fully compatible. So some won’t be fully operational from only a direct programmer swap / rewire.
