Elk M1 and HAI 1000 Tstat date problem

[Mike P]

I am in the process of upgrading my older style Hai thermostats with the 1000 units. I have replaced two so far. Everything seems to work fine, except for the day of the week. Today is Wed. one says Sunday and the other says Monday. The time and dates are fine. I see the time on the keypads change at the same time as the thermostats, so I know all comms are good. I just can't seem to figure out how to adjust the day. I have resent all data and have sent the time and date from RP. Still the same. What am I missing??

Thanks

This is an odd problem. The only thing I can figure is that the M1 doesn't send the day of week to the thermostat for some reason, so it stays on whatever week cycle it was on when it was powered up. Maybe try this: shut down your M1 for a few minutes. Manually set all the thermostats to the correct day and date. Then bring the M1 back up and see if it gets them all in sync.
