Hi,
I'm looking at using an AMX ENV-VST-C in place of an existing 2 channel heating timer/controller.
At the moment, the wiring is a channel each to CH and HW. If I'm understanding this right, the document at http://www.amx.com//techdocs/ENV-VST-C.OperationReferenceGuide.pdf (PDF, 1.32mb) shows what I'd need to do in Figure 9 (Page 19, but they show it as 13). I'd only need the radiant floor heat section, so I'd need to do that twice, thus:
W1 -> CH Relay
RC -> CH Relay
Boiler R -> CH Relay
Boiler W -> CH Relay
W2 -> HW Relay
RC -> HW Relay
Boiler R -> HW Relay
Boiler W -> HW Relay
...Right?
