## RULES
## - Hot Water Solar
# if ((temp_1 - temp_1_delta) < temp_2_set) && ((temp_2 - temp_1) > temp_1_delta) then relay_1 ON  <<< WTF?
# if (temp_2 > temp_2_set) || ((temp_1_delta / 2) > (temp_2 - temp_1)) then relay_1 OFF
# The controller running this mode compares four values: source temperature at sensor A (Ta), sink temperature at sensor B (Tb), target point (Tstop) temperature and minimal starting (Tstart) temperature as follows.
# The controller will switch relay output on, and will show Î (black triangle up) next to relay output status, when all the following three conditions are satisfied:
# •source temperature TA is greater or equal minimal starting Tst ar t temperature,
# • sink temperature TB is less that target Tstop temperature, and
# •the difference between source temperature Ta and sink temperature Tb , i.e. Ta − Tb , is above or equal to ∆ON degrees.
# When the difference Ta − Tb falls below or is equal to ∆OFF degrees (the last criterion is not satisfied), the controller displays È (black triangle down) and switches relay output off.
# Furthermore, if temperature Tb reaches target point temperature, i.e. Tb ≥ Tstop , then the controller displays Tm and the relay switches off. When temperature Tb falls below Tstop for 42 degrees, status of output relay depends on temperature Ta as described in this paragraph.
# When the starting temperature has not been reached, the controller displays a negative value, i.e. the difference Tstart − Ta, that is the difference between source and starting temperature.
# Note, that relay response might be delayed due to relay delay protection.
# Turn on ∆ON and turn off ∆OFF difference Values of ∆ON and ∆OFF are derived from 41 and 42 as minimum and maximum. For instance, if 41 < 42, then ∆OFF = 41 and ∆ON = 42. When 41 = 42, then 41 and 42 are adapted, eg. 41 lowers for 0.5 degrees and 42 increases for 0.5 degrees.
