Set It and Forget It!
Analog and Digital Heat Siphon models both have the same user interface design philosophy:
KEEP IT SIMPLE
Our first Heat Siphon model back in 1982 had just one knob with numbers from one to ten around the dial face.
Beside it were the simple operating instructions right on the label.
Basically it said, just turn the knob up all the way to 10 and let it run all day. When the pool gets as warm as you like it, then turn the knob down (counterclockwise) slowly until your Heat Siphon shut off. THEN DON'T MESS WITH IT AGAIN! Well, it didn't quite say that, but you get the idea. Today our Analog models still use that same single knob and our analog customers love it (or we'd have changed it).
DIGITAL MODELS - JUST 2 BUTTONS
The "D or DX" Digital Heat Siphon models have a 4-digit bright LED display that continuously shows you the water temperature and the temperature set-point for the current mode (pool or spa). There are two separate set-point temperatures stored - pool & spa and you may select either one at any time.
TO KEEP IT SIMPLE, the new DIGITAL Heat Siphon has just two buttons - UP and DOWN. Setting the water temperature and switching modes (pool spa or auto-pic) are simple:
- CHANGE the TEMPERATURE - just push and release either button and the current set-point flashes on and off for 3 seconds. Press UP or DOWN to raise or lower the set-point. After 3 seconds a beep tells you it has accepted your new set-point. Simple enough - DONE.
- SWITCH TO POOL (or SPA) SETPOINT -Press BOTH "UP" and "DOWN" at the same time and release. The display will flash the current mode ("PooL" or "SPA" or "Auto-Pic") .Then press either key until the mode you want is displayed. In 3 seconds a beep tells you the displayed mode is selected.
Any error conditions are reported and their codes are listed right there on the faceplate so you don't need a manual to tell what they mean.
