2.3 Freeze-Up Function in Cooling or Dry Keep
Applicable units R(Y)P71-250B
FHYCP, FHYBP, FDYP, FUYP, FAYP and FHYKP
Starting conditions In order to avoid formation of ice on the indoor heat exchanger in cooling and dry mode, the system
automatically starts up a freeze-up cycle when a number of specific conditions are fulfilled.
Starting conditions 1
The compressor has been running for less than A min.
The integral cooling capacity decreases for 200 s continuously (see integral capacity calculation
further in this section).
Te < -1°C for 1 min continuously (0°C for FAY indoor units).
Starting conditions 2 (FAYP indoor units)
The compressor has been running for more than A min.
The integral cooling capacity decreases for B s continuously and Te < F°C for 1 min continuously
(see integral capacity calculation further in this section), or
Te < -1°C for 1 min continuously.
Starting conditions 2 (not-FAYP indoor units)
The compressor has been running for more than A min.
The integral cooling capacity decreases for B s continuously (see integral capacity calculation
further in this section).
Te < C°C for 1 min continuously.
Starting condition 3
Te < D°C for E min accumulated.
Starting conditions 4
The compressor has been running for more than 1 min continuously while Te -5°C.
Compressor ON OFF.
Starting conditions 5
The compressor has been running for more than 8 min continuously while
the outdoor ambient temp. < -2.9 x room temp. + 79°C.
The compressor has been running for more than 8 min continuously while Te < -5°C for 1 min
continuously.
A, B, C, D, E and F The table below contains the values of A, B, C, D, E and F in function of the DIP switch settings on the
outdoor PCB.
