Heating limits
There are 3 heating limits which depend on the heating program.
1. normal heating mode
(house)
2. reduced heating mode (parameter 3-2)"only with clock program
to
"
3. heating limit heating circle flow (parameter 3-8)
1. Heating limit: "normal heating mode"
To reach an optimal comfort, the heating limit for the "normal heating mode" is cal-
culated as a function of the ambient temperature set point value. This heating limit
is effective in every heating program except the "reduced heating mode" (in the
manual Mode no heating limits are effective).
In the normal heating mode the heating limit
works if the adjusted room tem-
perature set point
is effective without change. The difference between these
two values is calculated. A change of the room temperature set point lowers the
heating limit about this calculated difference.
Formula:
Heating limit outdoor temp = room temperature set point actual (room temperature
set point
- heating limit
). The adjusted and/or calculated value of the hea-
ting limit is the point of switching off. Point of switching on is lower than the swit-
ching limit of 2K.
Example:
Room temperature set point normal heating mode
=
20
°C
heating limit normal heating mode
= 18 °C
The difference is
2 K
2. Heating limit: "lowered mode"
Using the automatic clock program
to
the adjusted heating limit (para-
meter 3-2) is effective as an absolute value.
