It's past my bedtime, but had to share.....
In the last couple of days I've noticed that my HVAC announcements (via dispatcher) have been failing to tell me when a hydronic zone gets activated or if the furnace runs. It always, however, does announce when a system shuts down.
I've been on the chat talking to - Bill -(ofWGJohns.com) and he's having a hard time believing me that 2 different powerflashes on 2 different unit codes are failing to send the on signal to 2 different cm15's on the same circuit (with 2 different AHP versions and 2 different SDK revisions) are seeing an "OFF" code being sent, but not the "ON" code.
In testing, I tried sending some lighting and appliance commands from a KeyPadLinc and a mini controller and they showed the module state just fine in AHP on both machines.
Mind you, the HVAC system was working just fine (in cellar on separate circuit, same phase as controlling PowerFlashes), just no logging on my computers.
For the record, I plugged my XTBM into a circuit on the opposite phase and tripped my thermostat and the commands showed up just fine.
On a whim, I put the XTBM in the living room and adjusted the thermostat to activate a water circulator pump (on appliance module) and the oil furnace (um506) to check the frequency count on the PLC from the powerflashes.
That's when I noticed that right after the "ON" transmission there was a sharp increase of noise on the line followed by a rapid decrease.
Then it hit me.
Last month I installed an electronic air cleaner on the blower.
Seems that the drop in voltage by the furnace or start up on a water pump was causing the air cleaner to have fits thus blocking the CM15A's from seeing the data.
I don't know how I would have ever solved this problem without the XTBM.
Thanks to Jeff Volp for the equipment and to Bill for helping me to preserve what little hair I have left.
You both get a +1 from me.
