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.
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.
