Max limit switch-off
value
Min limit switch-off
value
max  When a sensor reaches this temperature, the output is blocked.
(ex works = 75°C)
max  The output previously blocked when max  is reached is released when this temperature
is fallen short of. max generally limits storage. Recommendation: the switch-off point for
storage should be 3-5K higher (1-2K higher for pools) than the switch-on point. The
software does not allow for differences less than 1K.
(ex works = 70°C)
Setting range:
min  Above this temperature, the output is released. (ex works = 5°C)
min  The output previously released via min  is blocked at this temperature. min generally
prevents boilers from being clogged with soot. Recommendation: the switch-on point
should be 3-5K higher than the switch-off point. The software does not allow for a
difference less than 1K. (ex works = 0°C)
Setting range:
When the temperature difference between the two set sensors exceeds this value, this
diff 
output is released. diff is the basic function (differential control) of this unit for most
programs. Recommendation: In solar applications, diff  should be set to 7 - 10K.
Somewhat lower values suffice for the feed pump program. (ex works = 8K)
The output released previously when diff  was reached is blocked again when this
diff 
temperature difference is reached. Recommendation: diff  should be set at around 3 - 5K
(ex works = 4K). Although the software allows for a minimum difference of 0.1K between
the switch-on / off difference, no value below 2K should be entered due to transducer and
measurement tolerances. (ex works = 4K)

-30 to 149°C in increments of 1°C (for both thresholds, but max has to
