Hi everyone,

Some questions about UCM/Smartfit for those ahead of me on this.

I have firmware 5.43.

(1) The heating Setpoint shows as 69 in WizComfort 1.4.6 when the heating is off but a "normal" (expected) value when the heating is on. It announces the same value on the keypad in the home control menu too. Is this a bug in the UCM firmware?

(2) "Hot Water Demand" and "Heating Demand" counters.  Can someone please explain what these are and why they have a range 0 - 100%?. Are they only ever 0 or 100% or is there a condition when intermediate values will be seen?

(3) "Override room temp setpoint" counter.  I've not ever seen a value ever go into this counter.  I'm using the Wizcomfort Smartfit tab to look and play with these settings easily right now.  What would I need to do to see a value in here? Surely if I pick the "override Heating Setpoint" command and enter a new value and say the "hold" option (and execute) then surely this counter would show my new value?

(4) I'm getting the occasional "Invalid message type:SM" message on the errors tab in Wizcomfort.  I'm summising SM == Smartfit?  Any ideas what the errors are and should i be concerned?

I've attached some wizcomfort screenshots.

Regards

Julian

There may be others who are more knowledgeable about the Smartfit operation than us. We implemented the Smartfit LESSST protocol according to the information supplied by Honeywell in the UK (under a Nondisclosure agreement)
Some of the parameters like Heating demand and hot water demand are not clear to us. The UCM Smartfit receives the information from the smartfit and delivers the contents to the assigned counters.
If you want I can let you know our smartfit contact so you can get more information directly

I'd be happy to email your contact as a last resort but surely you also need to take some responsibility for the functionality here too as people are paying money for this UCM/solution.  You are  going to be able to apply more presure to your Honeywell contact for information than I as a "mere mortal" user can!

Also I've been "playing" with this UCM for "5 minutes" but it's been released for a few years now (it's one of the interfaces that attracted me to choosing Comfort in the first place) so I can't believe I'm the only one to observe this.

It would be nice to tidy up this functionality and release an updated firmwhere, surely? 

Regards

Julian

Interestingly enough for number (3) in my original post I've found that if I use the "override Heating Setpoint" command the new counter value doesn't go in "Override room temp setpoint" counter but instead seems to update the main "Room temp setpoint" counter instead.

Presumably why the "override" one is always zero value?
