PoolMaster V2.1.0

• LCD display now toggles between two screens every 6 seconds, shows more info
• modified PhPump() and ChlPump() functions to prevent the pumps from starting if Tank Levels are low
• Tanks Level errors now display error code on the LCD display but do not disable the PID loops or the filtering pump anymore, only the peristaltic pumps
• PID regulation loops start are now delayed for 30mins (by default) after the filtration start in order to let the readings stabilize first
• New API function to tell the system what the external temperature is. This is used to start regular short filtering periods of 10mins every hour when external temperature is below 2°C.
• Improved PID loops tuning
