2.3.2 NOTES ON TERMINAL BLOCK CONNECTIONS
NOTE 1 - Remote occupied/unoccupied
These contacts (from terminals 10 & 11) are to enable the air temperature set back facility to be remotely
overridden.
There is a 12 V AC output from these terminals and closing a remote switch will enable the unit to regain the
normal operating air temperature for when the pool is in use.
This can be done via a voltage free pool cover switch or some other form of voltage free switch.
If this facility is used then the time clock (if fitted) on the control panel of the unit should be set to the
‘unoccupied’ (o) position. (See note on time clock and switch settings, section 1.3).
NOTE 2 - Boiler demand -AA+LPHW machines only
These are voltage free contacts (from terminals 6 & 7) rated at 3(1) Amp at 230 Volts.
If the low pressure hot water supply to the unit is to be governed by the Calorex unit then these contacts should
be utilised to bring water to the unit via the boiler, motorised valve, boiler pump etc.
Remember the maximum
inductive load is one amp.
This is dependant on how the low pressure hot water supply to the unit has been designed.
If the supply of low pressure hot water to the unit is not dependant on a signal from the unit then these contacts
can be ignored.
NOTE 3 - RUNNING FAN IN ‘NON F’ MODE
If when the AA300 is installed the airflow is greater than necessary due to there being little or no ducting fitted,
the speed of the fan can be lowered, making the machine a non ‘F’. This is done by changing the fan speed from
high to medium by moving the white/black 1.0 wire from the electric box terminal 18 to terminal 17 (so that it is
now linked to blue fan lead).
CONTROL PANEL 25 WAY CABLE CONNECTION
Data signal between the console and the heat pump is via a 25 way cable with ‘D’ connection (plug & socket)
both ends. The cable provided with the heat pump is 1.8m in length. An optional 10m cable is available, part
number SD434052. A recommended maximum distance between the console and the heat pump is 20 metres, 2
cables being used.
