SP601 Description
The SP601 is a microprocessor based spa pool controller capable of implementing the
many features of an intermediate level spa pool. It offers the user complete control of
the following equipment via a poolside control panel:
•
1 x single pump + Aux load OR 1 x two speed pump
• Vairable speed blower (if Aux load not fitted)
• Small 24hr circulation pump *
•
Ozonator *
• LED pool light
• Pool temperature
•
Heating mode
• Filtration cycle
• Clean up cycle
* These are controlled automatically, so no user controls are provided.
In addition sleep times can be programmed via an optional, control box mounted clock.
Inside every SP601 is a 1.5kW, 2.0kW or 3.0kW flouropolymer coated element, an over
temperature cut-out device, a temperature sensor, a water sensor, and a controller
circuit board which includes an isolating transformer. To install the unit, a power supply
and digital switch are needed along with a suitable pump to circulate water through the
heater.
Initial setup of the unit can be as simple as setting the target pool temperature. The
unit’s sleep time, filtration function and heating mode can also be adjusted, if desired,
refer to the User Manual for full details.
Further customisation of the unit can be achieved by
adjusting the ‘Dip switch’ settings, which are located on the
controller circuit board. Features such as load shedding
(less / more), temperature sensor location (heater / pool),
main pump (1spd / 2spd), circulation pump (none / fitted)
can be altered at the flick of a switch. Refer to the setup
guide in the appendix. The pool builder / installer must
ensure these settings match the actual set up of the
system.
Each SP601 normally comes with a temperature sensor that is fitted to the heater
assembly. Alternatively an optional in-pool temperature sensor can be fitted instead.
The in-pool temperature sensor provides more accurate control of the pool temperature
and is effected less by variations in operating conditions (See the temperature sensor
section for more detail.) Both temperature sensors incorporate a solid-state digital
sensor that is accurate to 0.5°C. Only one sensor can be connected at a time and the
temp sense DIP switch must be set apppropriatly to tell the controller which is fitted.
