RELAY OUTPUT FOR EMERGENCY MODE
NOTE
Mark up any junction boxes with warnings for
external voltage.
When switch (SF1) is set to “ ” mode (emergency
mode), the internal circulation pumps (EP14-GP1 and
EP15-GP1) and the potential-free variable emergency
mode relay (AA101-K4) are activated. External accessor-
ies are disconnected.
The emergency mode relay can be used to activate ex-
ternal additional heat, an external thermostat must then
be connected to the control circuit to control the temper-
ature. Ensure that the heating medium circulates through
the external additional heating.

Caution
If the emergency mode’s operating voltage is
230 V~, voltage can be taken from AA101-
X5:1 - 3. Connect the neutral from the external
additional heat to AA101-X5:4 - 6.
REVERSING VALVES
F1355 can be supplemented with an external reversing
valve (QN10) for hot water control (see page 37 for ac-
cessory).
Connect the external reversing valve (QN10) to terminal
block AA101-X6:3 (N), AA101-X6:2 (operation) and
AA101-X6:1 (L) as illustrated.
With several heat pumps connected as master/slave,
connect the reversing valve electrically to a suitable heat
pump. The reversing valve is controlled by the master
heat pump regardless which heat pump it is connected
to.

display unit (as illustrated). Use the cable gland (UB3) in
the heat pump for cable routing.
