Parameter B035
(1) In case of single evaporator/condenser pump, also the
“
alarm evaporator/condenser pumps
” (AL016/017)
is activated. In case of double
evaporator/condenser pump, the latter is activated only when both
“
overload pump alarm
” (AL008
-009/AL010- 011) are simultaneously active.
(2) In the case of sensor NTC-HT, the alarm probe disconnected or below the value 0.0°C is given 60s after switching on the compressor.

A: automatic reset
M: manual reset
R: automatic reset with retries
