UNIT SAFETY
Description
Safety possible
if unit is off?
1. Emergency stop 0F0: EMERGENCY STOP Emergency stop button is pushed Y
2. Flow stopped 0AE: FLOW HAS STOPPED
(this safety becomes circuit
safety when unit type is ww,
double circuit and stepless.)
Safety is activated if the digital input is open for
more then 5 seconds
N
3. Freeze-up
safety
0A4: FREEZE-UP Safety is activated if outlet water temp is too low
(outletwatertemp < MOW-1.5)
Y
4. Inlet evaporator
sensor error
0C9: INL E SENSOR ERR Sensor out of range
(broken, bad contact, short circuit,...)
read-out for sensor (AI4) is +Er/-Er
Y
5. Outlet Evapora-
tor sensor error
0CA: OUT E SENSOR ERR Sensor out of range
(broken, bad contact, short circuit,...)
read-out for sensor (AI5) is +Er/-Er
Y
6. Ambient sensor 0H9: AMB SENSOR ERR Sensor out of range
(broken, bad contact, short circuit,...)
read-out for sensor is +Er/-Er
(only for air-cooled units)
Y
7. Inlet Condenser
sensor error
0HC: INL C SENSOR ERR Sensor out of range
(broken, bad contact, short circuit,...)
read-out for sensor is +Er/-Er
(only for water-cooled units)
Y
8. Heat recovery
inlet sensor error
(only on HR units)
0HC: HR INL C SENSOR Sensor out of range
(broken, bad contact, short circuit,...)
read-out for sensor is +Er/-Er
(only if Changeable AI= HR water cond inlet is
selected)
Y
9. PCOE
expansion board
error
0U4: PCB EXP
COMM.ERR
No communication with PCOE basically: for
units with 2 circuits and stepless compressors
then PCOE should be present. This safety is
only enabled if the error is present for 120 sec.
(default)
Y
10. ERAP
Thermostat
sensor error
0CJ: THERM SENSOR ERR Sensor out of range
read-out for sensor is +ER/-Er
(only for ERAP units) (broken, bad contact, short
circuit,...)
