Hcw82

[The EVOHOME Shop]

Let's say that the temperature program has 20° C as setpoint for a zone with an HCW82 installed, and this one is set to +3° C. What exactly happens? What setpoint is shown on the controller? 23? Showing a local override?
Thanks

Indeed, the HCW82 will 'offset' the setpoint temperature. So if the zone it is located in is 'scheduled' to 20 degrees and the HCW82 is set to +3 it will be +3 degrees on the evohome setpoint (i.e. 23 degrees). When the evohome Controller changes scheduled setpoint to say 16 degrees and the HCW82 was left at +3 it would actually control the room temperature at 19 degrees.

And I'm pretty sure the offset is purely local to the sensor. It isn't communicated back to the controller.
