Samson TROVIS 5500 - Summer Mode

EB 5573-1 EN 79
Functions of the heating circuit
Note:
The buffer tank control circuit is deactivated as described in section6.4. When pre-
dened gradients of heating characteristic (CO1 > F11-0) are used, night mode is
not possible in the buffer tank control circuit. In contrast to an active four-point char-
acteristic (CO1 > F11-1): in this case, a four-point characteristic exists for day and
night modes.

6.6 Summer mode
Summer mode is activated depending on the mean daytime temperature (measured between
7.00h and 22.00h) during the adjusted summer time period. If the mean daytime tempera-
ture exceeds the 'Boost' on the number of successive days set in 'No. days until activation',
summer mode is activated on the following day. This means that the valves in all heating cir-
cuits are closed and the circulation pumps are switched off after t = 2 x valve transit time. If
the mean daytime temperature falls below the 'Limit' on the number of successive days set in
'No. days until deactivation', summer mode is deactivated on the following day.
