TAC 200 User’s Manual
The outdoor temperature limits are set with
P:38 Outdoor temperature 100% night setback
(and 100% boost)
P:39 Outdoor temperature 0% night setback
(and 0% boost)
P:38 must always be greater or equal to P:39. If both values are set equal,
there will always be a full night setback, regardless of the outdoor tempera-
ture. Also the morning boost will have its maximum value for all outdoor
temperatures below the value P:38 (=P:39).
The boost time (time before Day time) and the amount of boost, in °C, are
specified with
P:40 Boost time (minutes)
P:41 Max-boost (°C)
The valid SP is calculated by removing any night setback and adding the boost
value determined by the outdoor temperature as shown in the figure.
If P:40 or P:41 is set to zero, the morning boost will be inhibited.
4.8 Extended day/night operation
Day operation is extended if terminal X1 is short-circuited to teminal M, via a
switch or a separate timer.
In the same way, night operation is extended if terminal X2 is connected to M.
This type of forced operation is indicated on the display by the flashing
apperance of the corresponding symbol. See also the description of P:00 in
section 3.2.
