If you have a Sanden Eco heat pump hot water system that is working but you find you're running out of hot water before your Sanden commences it's daily start up - this is most likely because you have a block out time period not suitable for your hot water load consumption.
Rectification is to change the Bllockout timer setting on your Sanden Eco heat pump (condenser unit) to either of the below Scenarios:
Most likely your current BO Timer is set up with a 5 hour period (e.g. "1611"- 11am to 4pm) - change this to either:
Scenario 1: Amend your Blockout Timer with a longer time period e.g. 0211
Keep the 'start' time of your Blockout Timer the same e.g. 11am to maximise rooftop solar PV production and change the 'end' time to e.g. 2am the next morning.
Your BO time on the control panel should read "0211" in this scenario.
Scenario 2: Disable the Blockout Timer
Find you're still running out of hot water? Disable the blockout timer.
Change the 'start' time of the Blockout Timer to "00" and change the 'end' time of the Blockout Timer to "00"
Your BO time on the control panel should read "0000" in this scenario.
