15.3 Refrigerant testing obligation
In accordance with the
F-Gas Regulation
(EU Regu-
lation 517/2014, in effect from 01/01/2015), a regular
leak test of the refrigerant circuit is required for air-to-
water heat pumps.
This test is based on the CO
2
equivalent of the ref-
rigerant used.
The heat pump
vamp
air
is filled with the refrigerant
R410A (hermetic system). The greenhouse potential
of 1 kg R410A corresponds to 2088 kg CO
2
-equi-
valent.
An annual refrigerant test obligation applies from 10
tonnes CO
2
-equivalent.

Refrigerant quantity

-equivalent R410A

-equivalent total
4.78 kg x 2088 kg/kg =
9980 kg

i.e. there is no testing obligation

i.e. there is an annual testing obligation

16.1 Possible messages
The overwhelming majority of occurring operating
faults require remedy by qualified personnel.
For some messages, switching off the heat pump (i.e.
de-energizing by switching off the circuit breaker) can
remedy the fault. You will be notified of this option in
the message window that appears in these mes-
sages (
..."disconnect the heat pump from the power
supply for 2 minutes
)

.
Overtemperature reset has triggered
The overtemperature reset (OTR) is a safety device
that prevents overheating of the electric heating ele-
ment (optional accessory). Function: The OTR stops
the heating element at a temperature of ~85°C. After
triggering, the OTR must be reset manually
. If
the overtemperature reset trips, this is indicated on
the control display.
