exchanger, compressors, electronic expansion valves, pressure sensors, temperature sensors, and
autonomous controller for the EVD expansion valves from Carel. A detailed description of the EVD
controller set-up, including commissioning, is given in a separate manual supplied by Carel. Heat
pump setup and commissioning is usually included with the AC unit manufacturer's delivery. The
number before the item name identifies the first or second circuit:
Circuit
– displays information about the operation of the heat pump.
Off
–
heat pump is switched off.
Cool
–
heat pump is operating in cooling regime.
Heat
– heat pump is operating in heating regime.
NoCool
–
heat pump is not cooling because the operating conditions are not met.
NoHeat
– heat pump is not heating because the operating conditions are not met.
Defrost
–
heat pump is defrosting.
Err
–
heat pump failed.
Power
(%) – current heating or cooling capacity of the heat pump.
PowerOn
(10%)
– minimum power required to turn on a circuit or compressor.
MaxPower
(100%)
– here you can set the maximum power limit of both circuits of the heat
pump.
DelayOff
(60 s)
– delay for the compressor to switch off after reaching zero power.
NextStart
(600 s) –
time between switching off and next switching on of each heat pump
circuit or compressor. Ensures that the compressors are not switched on and off too
frequently. The recommended maximum number of compressor starts is approximately 6
times per hour.
LeftTime
(s)
– displays the remaining time until the next possible circuit activation.
PID–Regulation
– factory default values are:
TI = 240 s, KP = 2, TD = 0 s
.
PowerCompensation
(
No
/
Yes
)
– compensates the maximum heat pump power relative to the
fan speed to ensure sufficient air is available. Between the
MinFans
and
MaxFans
fan speed
limits, the allowed maximum heat pump power varies linearly.
MinFans
(90%)
– if the current fan speed falls below this value, the maximum
allowable heat pump output drops to 0% and the heat pump shuts down.
MaxFans
(100%)
– at this speed, the heat pump can reach the preset maximum
MaxPower
.
