SC4D Space Age Controller for Solar Pool Heating Systems
The SC4D is a microprocessor based solar controller used to heat
your pool/spa from your solar
collector. The controller does this by constantly monitoring the
temperature on the roof and comparing
it with the pool temperature and desired setpoint. When the roof is
hotter than the pool the pump is
switched on to circulate water through the collector until the pool
reaches the desired temperature.
Advantages of an Angled Warming Plate
- System runs longer; modern high-flow collectors use smaller pumps which allows for longer running times for better turnover. Better turnover removes warm water surface stratification reducing heat loss overnight.
- Provides more accurate internal collector temperature readings than a lone roof-adhered sensor, this also allows for off-roof mounting for installations involving excessive cable run length.
- Turns system on faster; reducing the peak fatigue stress hot polymers experience on start up, also reducing the number of ON/OFF collector fatigue working cycles – extending the collectors’ lifespan.
- Better samples scattered ambient cloud energy, allowing longer run times during marginal collecting times; maximizing turnover and pool temperature, due to the mixing of the stratification layer.
- For split collector installations the plate provides a convenient way to split the collector angle on a roof.
Independent System Controller Comparison
* Tropical Mode will not function on this unit in Queensland Tariff 33, as it does not have clock and battery backup to retain settings after outage.
System Plumbing Options
This controller is used for setting up an independent solar pool heat system controlling a dedicated solar pool pump. We always recommend Independent Systems, see definitions below or manual. These systems run a small independent pump, typically for 8 hours per day and are actually more energy efficient than systems running through the main filter pump which have to run the large filter pump for 8 hours per day just to pump the solar side. Of course independent systems require separate solar suction and return lines, whereas for older pool these might not have been installed. If that's the case you'll need to go with a plumbing configuration that taps into your existing filter return line to divert water to your roof. There are a few configurations that can be chosen, see below or manual. Most people that do not have independent solar suction and return ports will choose a Manual/Timer System and place the main filter pump on a timer to run during the warmest part of the day. These manual systems can be automated down the track.
If you need to set up a specialized system like for a Booster/Retro Fit System (requires AquaSmart 5 FS or CD controller) or the Motorized Ball Valve System (requires AquaSmart 5 AV controller), please contact us at EcoOnline.
Requirements and Product Limitation
- This controller is used for setting up an independent solar pool heat system controlling a dedicated solar pool pump. Note: type of system requires independent solar lines running into your pool. Non-independent type systems such as a booster type system or systems running through the filter pump will require a different controller.
- This controller comes with a 20 meter wire for the roof sensor.
- Requires 14.0mm PVC pipe hole size for rubber grommet.
