9 Initial commissioning
Digital inputs
Depending on the switching state of the two elec-
tronic module inputs
[1]
i5 and i9
, four possible operating
states may result:
[1] Only connect potential-free contacts.
i5 i9
1 0 Operating state 1: The compressor is blocked
(electrical power block, maximum 2 hours)
The i5 input can therefore also be used as electrical power
lock info.
0 0 Operating state 2: Normal operation
0 1 Operating state 3: Recommendation to turn on
1 1 Operating state 4: Turning on
Switching state: Input bridged = logical 1, interruption = logical 0

9 Initial commissioning
i
Initial commissioning of the heat pump may
only be performed by certified, qualified per-
sonnel (SOLARFOCUS service technician, or
SOLARFOCUS service partner) (= condition
for guarantee, warranty).
i
Request commissioning at least 10 days
before the desired commissioning date at
SOLARFOCUS (see form DR-0104 for com-
missioning request at the end of this manual).
Requirements for commissioning
þ
The hydraulic installation of the heating
system is complete.
þ
The primary circuit was thoroughly rinsed, fil-
led and vented.
þ
The electrical installation of the heating
system is complete.
Conditions for commissioning
–
Volume flow of the heat pump (for the defrosting)
–
The required volume flow for defrosting the
heat pump must be reached. This is 1560 l/h
for the
vamp
air
K 08 and K 10, and 2500 l/h for
the
vamp
air
K 12 and K 15.
–
If the volume flow for the defrosting is not rea-
ched, then commissioning cannot be com-
pleted. Please check the hydraulic system for
dimensioning, blockages/correct position of
the switchover valves.
–
The return temperature from the primary circuit
must exceed a specific value (depending on the
outside temperature, see following diagram).

i
After having completed initial commissioning,
the completed commissioning form should be
returned to SOLARFOCUS. If this does not
happen, then for guarantee and warranty
claims of any kind the date of shipment from
the manufacturer to the dealer (according to
the delivery note and invoice) will be used.
