The temperature difference control
manages an output according adjustable
temperature differential criteria. The
function is independent from all the other
functions. TDiff1 is the temperature of the
heating source and TDiff2 of the heating
target. Output A3 will be switched on
regarding the conditions below, when a
timeframe is active.
A3 on TDiff1 >= TDiff2 + Diff.Tdmax and
TDiff2 < Diff.Tmax – 1 and
TDiff1 >= Diff.Tmin + 1
A3 off TDiff1 < TDiff2 + Diff.Tdmin or
TDiff2 >= Diff.Tmax or
TDiff1 < Diff.Tmin
9.1.8 Tube collector
Relevant values in menu
“Basic setting”: „Program“
4 -- 1 Timeframe (4) Start: min time
Timeframe (4) Stop: max time
The function „tube collector“ can be
switched off/on in the „Basic setting“ menu -
point 4. The timeframe 4 in the „Program“
menu makes possible to activate this
function only for a certain period of time
(Sunshine period). When activated, the
solar pump will be switched on every 30
minutes for a period of 30 seconds. This is
necessary, to measure a temperature
change in the collector, if there was no
circulating for a long period of time.
