4.7.1. Sensor design
Sensor lines have a cable cross section of 0.75 mm²
as standard.
The sensor positions are shown in the relevant
installation diagram. Reliable operation can only be
ensured by correct positioning and good heat transfer
(heat conducting paste).
If necessary, the sensors can be extended using a
suitable cable. It must be ensured that the connection
is clean and corrosion-free
Sensor lines should be run separately from mains
cables, (see EMC issue).
4.7.2. Sensor equipment
The following sensors are contained in the scope
of delivery or are already installed and, in any case,
required:
- Outside sensor, B32
- Heat pump heat fl ow sensor, B 33
- Buffer tank sensor (Return sensor heat pump), B39
- Heat source outlet sensor, B36
- Flow sensor heating circuit A, B51
- HW tap - temperature sensor, B42
- Hygienik sensor, B41
(All other sensors are optional depending on the sys-
tem equipment).
4.7.3. Flow temperature sensor
The fl ow temperature sensors for the heating circuits
used are required in every case. They must be con-
nected on the corresponding fl ow lines and in accord-
ance with the connection diagram.
The fl ow sensors for the heating circuits C-G are con-
nected on the respective heating circuit expansion
module. (see the installation instructions expansion
module for more information)
4.8. Impulse inputs
When using fl ow meters in the heat pump fl ow to
measure the heat volume they are connected as
follows:
A standard sensor set is included in the
scope of delivery for every heat pump.
The sensor set is inlaid in the electrical
cabinet.
