Brivis NC-3 / NC-4 Networker Thermostat
This has been programmed to control just one system - either heating or cooling (it is not programmed for a dual system ~ like heating and cooling). So if you have, for example, just a heater, then this should be suitable. I bought this recently off Gumtree, yet didn't realise it was only for a single unit (heat or cool) - not both - so I got caught out ... had to find another one for our dual system (heat & cool) ... grrr !! If you need a Heat & Cool unit, you will need an NC-6 Paid $60 If
