Connection of pool
Shuttle valves (VXV-P) is connected to the terminal
blocks X6A:1 (230 V), X6A:2 (N) and X6A:3 (NC) or
X6A:4 (NO).
The pool temperature sensor (PTG) is either fitted on
the circulation pipe for the pool water (presupposes
continuous circulation) or in a submerged tube in the
pool. The sensor is connected to screw terminals X1:3
and X1:4 on the EBV-card.

A shuttle valve (VXV-P) can be connected to control
one part of, or the entire, heating medium flow to a
pool exchanger. The shuttle valve, or, if required - the
shuttle valves (however, with the same control signal),
is/are installed on the heating medium circuit that goes
to the radiator system as normal. The compressor
modules that are connected via pool exchange valve
must be selected as available for pool operation in
menu 5.4.12 and 5.4.13. Circulation pump VBP3 must
be installed for pool operation.
During pool heating, the heating medium circulates
between the heat pump and pool exchanger using
the heat pump's internal circulation pumps (VBP-
A respectively VBP-B). VBP3 circulates the heating
medium around the heating system and additional
heat can be connected as required at the same time
as the flow line sensor (FG) continuously senses the
heating requirement of the house.
Start and stop temperatures for pool heating are set
in menu 6.5.1 respectively 6.5.2. Heating operation is
normally prioritised before pool heating, but shifting
between pool heating and heating operation can be
set in menus 6.5.3 and 6.5.4 if required. If the same
value is set in both the menus, heating operation is
prioritised before pool heating.
If several compressors are available for pool opera-
tion, these start at 5 minute intervals until no more are
available or the number of started compressors is the
same as the number that is selected in menu 6.5.5.
