Installation instructions geoTHERM VWS/VWW 0020057444_01
Phase monitoring
The sequence and presence of the phases (clockwise ro-
tating field) of the 400 V supply are checked at the ini-
tial commissioning and continuously checked during op-
eration. If the sequence is not correct or if one phase
drops out, a fault-induced shutdown of the heat pump
takes place to prevent damage to the compressor.
Freezing protection function
The outlet temperature of the heat source is measured
continuously. If the heat source outlet temperature falls
below a defined value, the compressor switches off tem-
porarily with error message 20 or 21 (see Chap. 10.4). If
these errors appear three times in succession, a fault-in-
duced shutdown takes place (see Chap. 10.5).
You can set the value (default setting - 10 °C) for the
freezing protection for geoTHERM VWS heat pumps in
Installation Assistant A4.
A value of + 4 °C is factory set for geoTHERM VWW
heat pumps. This value cannot be changed.
8.3 Settable auxiliary functions
You can set the following auxiliary functions from the
controller yourself and thus adapt the system to local
circumstances or the operator's wishes.
h
Note:
Operation of the controller is sub-divided
into three levels:
- Operator level -> for the operator
- Code level -> for the expert technician
- vrDIALOG -> for the expert technician
8.3.1 Auxiliary functions in the Operator Level:
Time programme
You can set the heating times for each heating circuit.
You can store up to three heating periods per day or
per block (Block = Mon - Fri or Mon - Sun or Sat - Sun).
See Table 8.3, Menu
3 "Timer programs".
Holiday programming
You can programme two holiday periods with date
entry. You can additionally define the set-back tempera-
ture to which the system should be regulated during the
period of absence.
See Table 8.3, Menu
4 "Holiday programming".
Party function
The party function permits you to extend the current
heating and hot water periods beyond the next switch-
off time, to the start of the next heating period.
See Chap. 8.9.
Energy-saving function
This function allows you to set back the heating for an
adjustable period of time.
See Chap. 8.9.
Cooling
Cooling mode is only possible when using the
VWZ NC 14/17 accessory, and only for VWS 14 and
VWS 17 heat pumps. More detailed information about
this can be found in the installation manual for the
VWZ NC 14/17 accessory.
8.3.2 Auxiliary functions in the Code Level:
Floor drying
You can dry out a freshly laid screed floor using this
function in accordance with Table 8.1. The flow tempera-
ture corresponds to a routine stored in the controller
and is independent of the outside temperature. All the
selected operating modes are interrupted when this
function is activated. See Table 8.4, Menu C6.

Table 8.1 Progress of the screed floor drying
The operating mode is displayed together with the cur-
rent day and the target flow temperature. The current
day can be set manually.
If the brine circuit is not yet finished, the drying of the
screed floor can be accomplished by means of the auxil-
iary heating. In order that the drying of the screed floor
can take place by means of the auxiliary heating, select
the value "
ZH only " for the "Heating mode" parameter
in Menu C7, "Auxiliary heating".
a
Caution!
Overloading of the heat source!
If too much energy is extracted from the
heat source while drying out a floor (e.g.
in the winter months), the source can be
overloaded and its
regeneration impaired.
