7.4.2 Summer period
Some functions depend on whether TAC 2413 is set for the summer
period or winter period. The cooling control is only allowed to apply,
and the pump for the heating coil is only allowed to stop, during the
summer period.
The parameter list contains adjustable “start months” for the summer
and winter periods, respectively. The period is started on the first day
of the set “start month”.
If the cooling demand applies all year round, set the parameters as
follows: P 47=1 and P 48=13.
P No. Parameter Min. Max. Factory set. Change Comment
P 47 Start month of 1 12 5
summer period
P 48 Start month of 1 13 10
