I have a Hayward H200 series gas heater for my pool. It has a digital readout with 2 temperature adjustment buttons and a mode button. I'm trying to find a manual online for the operation of this device but all I have found for this series of heater are versions with turnable knobs instead of the digital push buttons. I am new to pools and I would like read up on basic operation and what the modes mean/do.
Here's a poor quality picture.
