106:41ed3ea0bbba 2021-04-23 andrewboyson Not working, crashes. default tip
105:1899f7ed17ec 2021-02-23 andrewboyson Added ability to set the minimum flow rate and removed the correction to delta T relative to speed. Adding the round circuit time and linked to speed. Next task is to linearize the flow.
104:46ce1aaf8be7 2021-02-10 andrewboyson Added PWM speed control to the boiler pump.
103:15583327fcdd 2021-01-19 andrewboyson Updated settings after NR change
102:d7bc31f0ac6e 2021-01-16 andrewboyson Modified radiator frost and night temperatures to give one point (1/16 degree) of hysteresis. This prevents the radiator pump going on and off as the hall temperature sensor is between points.
101:77fd93f0bde1 2020-12-29 andrewboyson Updated to accommodate changes in the net library
100:fa45a545eb89 2020-11-27 andrewboyson Made ipv4 and ipv6 device names the same (they were ch4 and ch6).
99:84c3273dc77f 2020-11-05 andrewboyson Corrected toggle on home page to show radiator state (as labelled) rather than the override state (which is what is toggled to change the radiator state).
98:c75c959bcde3 2020-10-10 andrewboyson Following a power cut last night between 10pm and 2am I discovered that the override cancel set for 11pm did not happen as the module was not running. Solution was to not save the override variable in the FRAM so that it would be reset on power up.
97:84d58bf7a835 2020-10-04 andrewboyson Added bound checks to radiator settings
96:18a3813bb4b5 2020-10-03 andrewboyson Added override cancel time to UI.
95:97621bfbedfa 2020-10-02 andrewboyson Added 11pm override cancel for the radiators as we kept forgetting to remove the override if used in the summer. Space in the Fram memory for the minute in the day to cancel was found. Still to do the web UI.
94:ded7c74d49fb 2020-06-11 andrewboyson Added hot water temperature to values being recorded and sent to tftp.
93:5ee0a1ef0279 2020-06-10 andrewboyson Added hot-water files to heating module
92:2d1ca4dcbca7 2020-06-10 andrewboyson Made changes to the javascript in web pages displaying temperatures in line with the changes to the 1-wire library.
91:8b192efd0288 2020-06-10 andrewboyson Changed the run on residual to a fixed 4 bit fraction temperature to allow better than one degree precision.
90:1c504a7b465e 2020-06-04 andrewboyson Put a check in heating/values module that strftime had successfully produced a filename from the template.
