General
If the integrated AUX relay in the heat pump is busy,
this accessory can be used to enable the connection
and control of the following functions:
• hot water circulation
• blocking of supply air heating (accessory BSA 10)
• control of external frost protection damper
• external heating medium pump (GP10).
HOT WATER CIRCULATION
One pump can be controlled for the circulation of the
hot water during selectable periods.
BLOCKING OF SUPPLY AIR HEATING
(ACCESSORY BSA)
This accessory is used to block supply air heating in
F470 at the same time as some heat production is re-
quired in all, or parts of, the waterborne heating system.
For example, it is possible to block preheating of the
supply air but still obtain heat from the underfloor heat-
ing system in the bathroom in the summer.
Settings are adjusted in menu 4.9.2 after the accessory
AXC 20 has been activated.
CONTROL OF EXTERNAL FROST
PROTECTION DAMPER
The frost protection damper must be dimensioned to
seal against the underpressure that can be created in
the house, for example when a fire is lit in a stove with
the heat pump switched off. An external supply air duct,
for example to the stove, is recommended.
EXTERNAL HEATING MEDIUM PUMP (GP10)
An external heating medium pump is installed in the
climate system and can be controlled from the heat
pump.
