DESCRIPTION
Circuit A compressors, command status
b
1
= compressor A1
b
2
= compressor A2
In test mode, the Arrow buttons display 01 and 10 in succession, so as to force the status of the compressor outputs in turn.
During the test phase, power to the compressor is switched on for 10 seconds only. It is then not possible to restart the
compressor for a further 30 seconds. When the test is completed the following is displayed:
- Fail: displayed if the test has failed because the compressor was not started or run in reverse rotation.
- Good: displayed if test was successful
Circuit B compressor, dual-circuit units only
b
1
= compressor B1
b
2
= compressor B2
In test mode... as above
Number of fans in operation, circuit A, remote condenser
Number of fans in operation, circuit B, remote condenser
Number of fans in operation, drycooler
Evaporator water pump #1 control status. Not displayed if the unit does not control a pump.
On: pump is running
Stop: pump is stopped
Forc: this item is displayed only when the unit is stopped locally (LOFF). selecting this item authorises turning on the
pump with no delay and for an unlimited length of time. The pump will remain on until one of the user interface buttons is
pressed: it is then immediately stopped.
During the test phase, power to the pump is switched on for 10 seconds only. When the test is completed the following is
displayed:
- Fail: displayed if the test has failed because the pump was not started
- Good: displayed if the test was successful and the water flow switch presence contact is closed.
Evaporator water pump #2 control status. Not displayed if the unit does not control a secondary pump.
As above
Condenser fixed-speed water pump #1 control status.
As above
Condenser fixed-speed water pump #2 control status.
As above
Condenser variable-speed water pump #1 or condenser open-loop water pump control status.
nnn: Pump speed in %
As above
Condenser variable-speed water pump #2 or condenser open-loop water pump or three-way valve control status.
nnn: Pump speed in % or valve position in %
As above
Alarm output command status
b
1
= alarm circuit A
b
2
= alarm circuit B
In test mode, the Arrow buttons display 01 and 10 in succession, so as to force each alarm output status in turn.
Boiler command status. Displayed if the unit controls a boiler. See section 5.13.
Variable fan speed, drycooler or circuit A. Displayed if the unit controls a variable-speed fan in a drycooler or remote
condenser.
Variable fan speed, circuit B. Dual-circuits only and if the unit controls a variable-speed fan.
Pumpdown solenoid valve status. In test mode, the arrow keys successively display 01 and 10, in order to authorise the
test for each valve in turn.
b
1
= valve circuit A
b
2
= valve circuit B
This item is only displayed for units with remote condenser.
Used for local interface test only. Lights or flashes all LEDs and blocks, so as to check that they are working properly.
1 This item is displayed in certain unit configurations only.
2 Testing authorised only if the unit is in Local Off and all compressors are off.
3 Password needed only for testing.
“Test” Displayed in turn with the item value during tests.
