When solar and heater are enabled the solar will heat
the water until either the thermostat setting has been
reached or solar heat is no longer available. If the solar
panel is not hot enough, solar heat will shut off and the
other heat source (usually gas heater) will take over to
bring the water up to the thermostat setting. This menu
is used to ENABLE or DISABLE the solar priority.
NOTE
Depending on the position of DIP switch S2-1 and
the presence of a solar or heat pump sensor, SOLAR
PRIORITY or HEAT PUMP PRIORITY may be
displayed on the SYSTEM SETUP menu. It is not
possible to have both SOLAR PRIORITY and HEAT
PUMP PRIORITY displayed on SYSTEM SETUP
MENU at the same time. It is one or the other.
10.2 Heat Pump (Heat Mode)
NOTE
This equipment may not be part of your system.
Please check with your installer.
The HEAT MODE selection controls the heat pump
operation.
10.2.1 Heat Pumps Controlled by Extra
Aux/Solar Boost Relay
In order to use the heat pump, the filter pump must be
turned on and the heat pump must be in HEAT MODE,
and the switch on the heat pump on the equipment pad
must also be set to HEAT MODE.
NOTE
HEAT PUMP takes the place of EXTRA AUX or
SOLAR HEAT. It is not possible to have any two (2)
of these on the EQUIPMENT ON/OFF menu at the
same time.
To operate the HEAT PUMP in this type of
configuration, set the DIP switch S2-1 to ON and
connect the HEAT PUMP temperature sensor to the
SOLAR SENSOR input.
10.2.2 Heat Pumps Controlled by the
RS485 Interface
In order to use the heat pump, the filter pump must
be turned on and the heat pump must be in the HEAT
MODE.
NOTE
In this configuration, it is possible to have the HEAT
PUMP and SOLAR HEAT on the DEVICES ON/OFF
at the same time.
NOTE
If both HEAT PUMP and SOLAR HEAT are to be
controlled by the system then set the DIP switch S2-1
to OFF and connect the SOLAR SENSOR to the
SOLAR SENSOR input.
NOTE
If SOLAR HEAT is not to be controlled by the system
then set the DIP switch S2-1 to ON and connect
the HEAT PUMP temperature sensor to the SOLAR
SENSOR input.
